Proper information on the welding process - Overview
Correct info on the welding process is mandatory for people that would like to learn welding and also for people that would like to improvise their welding abilities.
most frequently folk are interested to start a job in welding and some others would like to take their career to a different level.
Essentially welding is the method in which base metal parts are liquified and joined employing a filler material which has the same traits of the parent metal.
there are various kinds of welders specifically Arc welders, Mig Welders, TIG welders and Gas Welders. Among these types, Tig Welding is regarded as one of the hardest type to learn and master.
TIG welders often known as the Tungsten Inactive Gas Welders uses an arc which is made from non-consumable tungsten. The heat for the welding process is generated using electrical current. This sort of welding has many advantages like its high amperage permits welding of metals with great thickness. Other benefits include the concerns related to pureness of metal and cleaning.
It's not at all a straightforward task to conquer TIG welding. Sometimes all of the other welding strategies permit the welder to simply manage with one hand. The method involves great quantity of concentration as the welders use both the hands to control the welding area while adding the filler material to the surface. For safeguarding the welding area from airborne pollutants, the welding uses inactive gases like argon.
Due to this process, the welding would be clean and exact. The welding brings in huge power of light and if the eyes are immediately exposed, it leads to the burning of retina called as arc-eye. A face guard to shield the eye from actual exposure to intense levels of light is a complete must for all the welders. The entire body should be properly covered during welding as the exposed light carries UV radiation that's dangerous to the skin. Like all other sorts of welding, the TIG welding also gets less difficult with practice. For a noob, it is recommended that he must practice with scrap metal stock before attempting any real projects. This sort of welding is highly complex and is mostly costly than the other types as the newbs hesitate to buy the Welding Kit. However, the elevated price is worth as the product carries a variety of benefits compared with any other.

How to make a sliding gate for driveway?
I am trying to make a sliding gate and could do with some pointers.
The gate will be 4m wide x 1m high. I am getting it made from wrought iron by a local blacksmith. But Although I know it needs to be on wheels running in a track, I don't know where I can buy them from. I am thinking that I need about 8-9m of RSJ buried in the ground where the gate will slide along with a metal dowel welded to it, then the gate should have wheels which run on the dowel. But I have no idea if this is the best method or even the correct way of doing it. On top of this query, once the gate is sitting on its track or similar, how do you support the top so it stands upright?
Ultimately once the gate is working I plan to add an electric gate kit so it can be opened from the car - so all in all it is quite a big DIY project...
So any advice or weblinks or advice greatly received - especially in respect to where I can get these from.
Thanks
A metal shop should have a roller that helps support the gate at the top to hold it upright, and make sure it opens right. It is U shaped and fits over the top of the gate.You could also use a caster and U channel steel. anything to keep it straight.

Chakras are centres of psychic energy located at points along the spinal cord. They are associated with the five elements: earth, water, fire, air and ether. Each chakra corresponds to a specific mantra (sound) and geometric pattern (yantra). Through meditation on these chakras we can gain mastery over our body and each corresponding element.
The human organism is not just a physical composition or structure made of molecules but is also composed of energy fields. These energy fields or the centers of psychic energy are popularly known as chakras. There are seven major chakras which are situated along the spinal cord against the points of five major nerve plexuses and endocrine glands. These chakras are very important for energy balance and perfect synchronization of interior and exterior rhythms or HEF (human energy field) and UEF (universal energy field). Chakras are bioplasmic energy fields composed of ions, free protons and electrons. This state is distinct from four known states of matter i.e. solid, liquid, gases and plasma. Hence chakras are fifth state of matter. The energy field of these chakras can be measured by SQUID, EEG and kirlian photography. A normal developed and opened chakra always spins clockwise and gains pranic energy from UEF while counter-clockwise movement of a chakra makes energy flow out which makes a chakra closed, sick and abnormal.
In Chetna Therapy through constant practice of dhyan (meditation), mantra jap (mantra recitation) and darshan (visualization) one can rebalance the distorted energy system of chakras to be free from diseases. For example, in cancer the Manipur and Visudha chakras lose their protective sheath which can be cured by Chetna Therapy.
Muladhar chakra is a yellow square with four vermilion petals. The square represents earth element related to predominant sense smell and sense organ nose. This chakra governs spinal column and kidneys and effects the functioning of adrenal gland. A well balanced and strong Muladhar chakra gives a strong will to live while a weak and imbalanced chakra gives a tendency to suicide, violent behaviour, inferiority complex and feelings of insecurity. In polio and cerebral palsy this chakra bends towards the side of the healthy leg. Persons dominated by this chakra usually sleep on their stomach between ten to twelve hours daily. In Chetna therapy Muladhar chakra is aroused by chanting of the Bija mantra "Lam" 56 times. This should be followed by colour energy by covering the patient with yellow cloth.
The second chakra, Svadhisthana, is in the form of a circle with a crescent. The colour is Light Blue. It represents water element related to predominant sense of taste and sense organ tongue. This chakra controls kidneys, bladder, reproductive organs and large intestine of the body and gonad. It is very closely related to the quality of love and sex. If this chakra is normal the person enjoys mental and physical well being. If it is blocked the individual will be impotent with premature orgasm. In AIDS and sexually transmitted diseases Muladhar and Svadhisthana are clogged. Bladder diseases, enlarged prostrate, hydrocele are associated with this chakra. To arouse this chakra one should first of all concentrate on water or by gazing at the crescent moon for half on hour daily. Repetition of Bija mantra "Vam" 51 times daily definitely enhances sexual vigour and vitality. This chakra is also very closely related to the effectiveness of mental activities, attention, concentration and meditation. Keeping a picture of this chakra in front of you and concentrating on it elevates creative and sustaining energy in the individual and a feeling of peacefulness. A person with an active Svadhisthana chakra sleeps eight to ten hours in a foetal position, often pretends to be a prince or hero maintaining high self esteem. For proper functioning of this chakra one should keep fast on ekadashi (eleventh day of lunar month).
The third chakra, Manipur, is in the form of an inverted red triangle located in a circle of ten petals with a golden colour bijakshar (seed). It represents fire element related to predominant sense, sight and sense organ, eyes. This chakra controls liver, pancreas, stomach, spleen, gall bladder, small intestines and sympathetic nervous system. The proper functioning of this chakra is necessary for the digestion and absorption of food. Anger and frustration causes depletion of this chakra energy. Indigestion, irritable bowel syndrome, peptic ulcer, gall bladder diseases are all associated with a malfunctioned Manipur chakra. Alcohol makes the chakra totally disfunctional. This chakra is also related to the emotional life of an individual. If the chakra is closed and not functioning harmoniously the person will have uncontrolled extremes of emotion which may result in hypertension and adrenal exhaustion. Many times this center acts as a block between heart and sexuality as the center related to health i.e. Anahata is above it and center related to sexuality i.e. Svadishthana is below. If both these chakras are functional and open but Manipur is blocked then a person's sexual life will be without emotional attachment and love and vice-versa. Repetition of Bija mantra "Ram" 108 times daily and wearing a string of rudraksh beads keeps the chakra in harmony and balance. Whenever a person is under heavy stress and tension a mere visualization on this chakra for 5-10 minutes with repetition of seed mantra will give immense soothing effect. Whenever concentrating on this chakra one should concentrate specially on the navel.
The fourth chakra, Anahata, the most important chakra of the body, is in the form of a hexagram of a grey-green colour surrounded by 12 vermilion petals with a golden bijakshara. It represents ailment associated with sense of touch and sense organ skin. Associated with cardiac plexus it controls functions of heart, lungs, thymus and blood circulation. Congestion in Anahata chakra causes heart problem and related diseases. Excess of pranic energy in this chakra causes heart attack. In this case the inner aura may extend up from 6" to 3 feet. Asthma is another example of the hypofunction of this chakra. Within Anahata chakra is an eight petaled lotus in the center of which rests the spiritual heart or anand kanda on the right side very closely related with the physical heart on the left. An increase or decrease in the rate of heart beat serves as a warning signal that there is some abnormality in the anand kanda. The fourth chakra has a lingam also known as banalingam. This lingam radiates golden light and is formed from a mass of tissue in the nerve center at the Anahata chakra clearly visible in kirlian photography. "Om", the unstricken cosmic sound is a wondrous treatment for all heart ailments. Patients can be tremendously benefited by the pure musical tones of "Om". This chakra is also a seat of balance within the body with three chakras above and three chakras below distributing a uniform energy flow in both the directions. The person with an active fourth chakra sleeps from 4 to 6 hours on his left side.
The fifth chakra, Vishudha, is in the form of a crescent of silver within a white circle surrounded by 16 golden petals. It deals with creative energy and sound in the body. It controls voice, oesophagus, vagus nerve, respiratory system, thyroid and parathyroid glands. It represents Akasha element associated with sense of hearing and sense organ ears. Blockage at this chakra causes dumbness, hypofunction of thyroid and sometimes difficulty in swallowing food and water. Sweet and melodious voice of singers is a virtue of harmonized Vishudha chakra. This chakra is also referred to as the professional center because if one is successful and satisfied with his job the center will be full blown. Fear of failure, competition and of not being liked blocks this chakra. Meditation on this chakra gives calmness, melodious voice, leadership traits, command of speech. The seed mantra of this chakra is "Ham", repetition of this mantra 101 times helps to normalize this chakra. Constant meditation on this chakra makes one youthful, free from old age wrinkles or aging defects. The person with active Vishudha chakra sleeps little, generally 6 hours, constantly changing sides.

What is the best air compressor for an INVERTER PORTABLE AIR Plasma Cutter (1/4"-1" capacity)?
Check the airflow rating of the cutter (volume per minute at a certain pressure) and make sure the compressor can produce at least that much volume. If not, you will have to interrupt your cutting periodically.
"I've been using this MIG wire for the last six months without a problem". "Now after having used many spools the wire its gone bad". "What's happened?
Sound familiar? The trouble here is that the person or company that you bought your MIG wire from cannot guarantee you quality.
Did you buy the cheapest stuff you could find? Ha-ha...As the saying goes, "he who buys on price, and price only, gets what he paid for".
Sounds harsh but that's the truth. Quite often you find end users happily welding away with their current brand of MIG wire. When all of a sudden they go and open up the next new pallet of wire that just arrived, slap it on the machine and the welds are all over the place.
Spatter, burn backs wire not feeding properly and so. What's going on, they think to themselves. "Ahh, I know, it must be a worn Contact Tip". So off they go and replace the contact tip with a new one. But no, sure enough same problem. "Well, it's been a while since I change the liner". So off they go and do that. Yet sure enough the same problem is still there.
They think to themselves, "well I've changes everything else, it can't be the wire. It's brand new and I've been using it for over six months without any trouble".
This is such a common thing to come across in the welding industry, and it affects everyone throughout the world. Whether you're in the USA, Australia, New Zealand...anywhere.
So what is it, what's the problem?
The problem is quality.
The person who is supplying your wire can not guarantee you quality. But you think to yourself, it can't be the wire, no way. I've been using this (xxxx) brand wire for ages. They are a huge massive company, they sell MIG's, TIG's all sorts of welding gear no way can it be the wire that's giving me problems....can it?
The trouble is that unless you are guaranteed the quality of you welding wire your "up a creek without a paddle", so to speak.
With so many people selling welding wire these days it is extremely hard to come by a quality wire. The majority of goods made in the world today come from China or India. With huge populations and low wages, they are the cheapest places to buy things from.
There are over three hundred manufacturers of welding wire in China alone. What does this mean to the quality of your MIG wire?
This means that if the brand of wire on the box is (xxxx) they are not the manufacture of it. You need to ask the sales person....ARE YOU THE MANUFACTURER OF THIS WIRE?
Because what happens behind the scenes is the company you bought the wire from has a big argument with their supplier in China or where ever. And they say stuff ya....well go next door and buy from them. Hey with over 300 manufacturers in China alone they can pick and choose who they like.
So they change their manufacturing supplier, and this happens all the time. But when they change manufacturer the quality also changes. That's why your wire has gone bad. And that's why they can't guarantee you the quality.
Simple as that.
Each time they change their manufacturing supplier the quality changes as well. There is a huge difference in quality of wires.
Okay so what do I do now, which wire do I buy?
The secret is to buy a wire that is supported by the manufacturer. You need a manufacturer that has been producing quality welding wires for years and years so that they have the art perfected.
Did you know that there are general "quality" MIG wires and precision MIG wires? Which type of wire do you think that the big boys use? When I say that I mean vehicle manufacturers, earthmoving manufacturers and so on, company's that use it by the tonne. What do you think they are after in a welding wire?
They are after:
• Precision
• Reliability
• Repeatability
• Consistency
• Quality
• Accuracy
How much money would Toyota or Mitsubishi or Caterpillar lose per minute if a welding machine was down? I sure bet it would be an awful, awful lot of money. These manufactures don't want a single welding machine in an assembly line to break down. Cause if one thing stops, the whole show stops.
i have some wire i think it is stainless , i'm trying to put it onto Mig Welder , but it come through gun but
right where the spool meets the sleve of welder gun....if i do get this together how will stainless weld on Mild Steel ., i have safety equip just don't have much reference on this machine or application help ! please
It sounds like to me that you have the wrong size wire for your welder. There should be a mark on the welder somewhere stating the wire size e.g. .027, .035, etc. If you are going to use stainless wire then you will need to use argon gas . Stainless wire should really be used for welding Stainless Steel. You really should use a mild steel wire to weld all other kinds of steel. You can use either carbon dioxide gas or a tri- mix. Some welders don't require gas at all if you are using Flux Cored wire.
The smaller the wire size , the thinner the metal that can be welded. If you are using small wire then you can only weld up to about a 1/4 " thick steel on a single pass. The small wire isn't recomended for welding anything thicker. But you can weld metal very thin with the thin wire
Welding sheet metal is a complicated job that necessitates precision, accuracy and safety procedures. One of the common problems often encountered by welders working with sheet metal is that they can easily make huge holes instead of welds. Without the proper skills and techniques, the heat can immediately melt the metal and the liquid metal will fall out of the part that is being fabricated.
When welding thin sheet of metal, the primary goal is to prevent distortion, burn-through and extreme heat-affected zones while making sure the weld has enough strength for the application. Contrary to popular belief, welding is not as simple and easy as heating the metal then fabricating it to the desired shape or size.
Specific types of sheet metal need specific control over heat. There are numerous welding processes that can be done to weld sheet metal such as short circuit transfer gas metal Arc Welding (GMAW), pulsed GMAW, gas tungsten arc welding (GTAW) and pulsed GTAW. Dissimilar components cannot be welded due to their varying melt properties and thermal conductivities. Nickel and chrome plated metals, for example, are easy to spot weld. On the other hand, sheet metals such as aluminum and tin need special preparation inherent to the coating metals.
The task of welding sheet metal starts from preparation and cleaning. Clean the metals, particularly aluminum, prior to welding. Use a solvent or degreaser to eradicate oil and dirt. Aluminum accumulates oxide layers when it is exposed to air. Before even welding it, remove the oxide using a Stainless Steel wire brush or chemical oxide removal solutions. Make sure the degreaser does not have any hydrocarbons.
Take note that aluminum oxide on the exterior of the material melts at 3,700 fahrenheit while the base-material aluminum will melt at 1,200 fahrenheit. Leaving any tinge of oxide on the surface of the base will hamper diffusion of the filler metal into the workpiece. Inefficiency in preparation degrades the quality of output, so be meticulous when cleaning it.
To ensure safety while welding sheet metal, you should work in a ventilated area to prevent build-up of harmful gas emission. Proper welding clothes, eyewear and leather gloves are also necessary. Sheet metal has sharp edges. Aluminum, in particular, is very springy and it can accidentally jump at you. Wearing the proper Welding Gloves can save you from a painful cut.

I am shopping around for a Tig Welder, as anyone would see, tig is a fairly expensive feature on a welder. I have spoke with a few guys (they are trying to sell their TIG) and they often state that the pulse feature is entirely unneeded. I really can't say so one way or another so I am hoping for some great personal feedback.
Thank you!
When you talk about pulse tig it is mostly DC welding. You use the pulse to help reduce the distortion. It is mostly used on all ferrous metals. You do not need or have the pulse feature on AC for aluminum. You would need an AC or AC/DC machine for tig welding aluminum. They are some what costly. When tig welding you need to stay with the better name brand welders. Thermal Arc, Hobart, Miller, and Lincoln are all good machines. To weld 1/4" aluminum you need approximately 200 or more amps. So this puts you into a machine that is in the $2000 range. Then you need a bottle of argon gas. If welding for any length of time at those amps you would need a Water Cooled torch. Not to mention the water cooler, Foot Pedal and all the other items needed. All these items are costly. I am not trying to discourage you but you need to know it is going to cost you some bucks to invest in all the equipment you will need. Good luck!
