TIG Welding Guide
Welding is the process used for fusing materials such as metals etc. There are many methods of welding processes like gas welding, arc welding, and resistance welding. TIG or Tungsten Inert Gas may be described as a type of gas metal arc welding. Instead of flux coated electrodes, a gas shield is used to purge oxygen from the weld path. Bare wire is fed into the gas shield area while the tungsten electrode burns the bare wire fusing the bare wire to the parent metal.
One of the major advantages of a TIG welder is higher amperage which allows for the greater thickness of metal to be welded, amongst other advantages relating to the purity of the metal, cleaning etc. Welding with TIG demands the workpieces to be prepped an cleaned properly.
TIG is an acronym for tungsten inert gas welding, and it differs from other forms of welding in that it makes use of an arc which is created from tungsten, and which uses an electrical current to generate heat for the welding process.
TIG welding is one of the best techniques for welding and manipulating aluminum, though the downside of TIG welding is its incredibly high cost, it is very expensive and most likely to be out of the price range of most amateurs and hobbyists, with even a modest, low specs welding kit priced at $1600. The price tag does carry with it a number of major benefits in comparison to other forms of welding.
The high price is not the only major obstacle people have to overcome in regards to successfully learning to use the TIG welding, TIG welding has an extremely steep learning curve, and it is a difficult skill to master. With such a high initial cost and so little room for failure, it really takes a special kind to truly succeed with TIG welding. Succeeding at TIG welding also requires a real focus in attention as most welding methods allow the welder to get away with simply using one hand, not so with TIG welding.
Another drawback of TIG welders is that you cannot simply use your gas tank and other kit from your MIG welder with your TIG welder, the TIG welder is equipment specific. TIG welders make use of inert gases such as argon so as better protect the welding area. This really should be a well-drilled into your head already, but safety must be paramount at all times, TIG welding is still fraught with all of the dangers associated with welding, and so proper precautions have to be taken.
Due to the intense levels of light that are created during the welding process, this poses a very real danger to the welder of developing so-called “arc-eye”, a burning of the retina which will lead to permanent blindness. Even limited exposure to the light can in time have a lasting effect, so a face guard to shield the eyes from direct exposure is crucial. The light also carries another great danger UV radiation, this is known to cause skin cancer, and so no part of the body should be directly exposed during the welding process.
Due to both its specialized nature, steep learning curve, and relatively low-cost maintenance, TIG is commonly used and employed within the automobile and spacecraft industries respectively, and TIG welding also has a great advantage that the finished materials and alloys created are highly resistant to corrosion and cracking even over a prolonged period of time.
Welding, unlike soldering and brazing – two things that are usually mistaken to involve a similar process as welding, uses coalescence to join metals or thermoplastics. This is done through melting the workpieces and adding another material to create a weld puddle which, when cooled, becomes a strong joint and produces the weld. So a weld, in case you’re still wondering, is simply a joint formed by welding.
To produce a good weld, first, you need to make an arc. With this arc, create a weld puddle and put fill metal on it and push it along the weld joint. Finish the arc. Let the puddle cool and protect it by leaving the torch over it. In Tig welding, it’s also important to establish a good electrical contact between the tungsten and collet. This way, current transfer and weld quality can be improved. Practice good maintenance for your welding tools by keeping your tig torch components tightened always and checking them regularly for worn parts. You should also clean your weld joint and the filler metal by removing oil, grease, and dirt, as these elements may cause arc instability or dirty welds.
Dangers Of TIG Welding
The three most common problems encountered by the operator in TIG welding are an erratic arc, high electrode consumption and porosity of the weld. But if you can only identify and rectify the problems, you will save enormous time and money and the weld can be achieved faster. One of the chief problems of TIG welding is porosity. Porosity may be described as gas pockets formed in a metal weld. The reason for porosity may be due to improper coverage of shielding gas, the use of inappropriate shielding gas or filler metal, too much heat and a base material that is not cleaned properly.
Lack of fusion is another major problem that can occur in TIG welding. If the weld does not join with the base material then it will lead to a weak joint. Experts suggest that to have the best TIG weld, you should use 10 amps for every thousandth of an inch of material. To avoid TIG welding problems, take care to tighten all torch fittings and examine all the holes for possible leakages. If a hose is weak or damaged, it is best to replace it forthwith.
Stay Technical With The TIG Process
Please know that the shielding gas flow rate must be 10 to 20 cubic feet per hour. If the rate is higher it will lead to weld puddle turbulence and if it is lower it will not protect the weld puddle. An incorrect rate of flow will result in porosity. The appropriate filter rod should be selected for the base material. Use argon gas shielding and not CO2. This will also prevent porosity. TIG welding is best performed using argon gas instead of a gas mixture or carbon dioxide.
Excess heat can also cause porosity. You have to remove dirt, grease and surface oxides from the surface of the material using a stainless steel brush to avoid porosity. Undercutting is yet another common problem with TIG welding. This happens when a groove is made along the edge of the weld and then you fail to fill the place with weld metal.
When welding a joint create a space between the joints or bevel the pieces that form the joint. This will facilitate proper fusion of the joint. If the welding arc is unduly long, you may obviously be holding the tip of the torch far away from the metal. Make sure to keep the torch tip less than 1/4 inch from the metal. Do not to touch the tungsten tip to the metal.
