TIG Tungsten Electrodes TIG Tungsten Electrodes Tungsten Inert Gas (TIG) welding is a popular type of welding that utilizes tungsten electrodes to join various metals. The tungsten electrode is a critical component in the process, as it channels the current required to establish the arc. The tungsten electrodes can be alloyed with a variety of metals. Different types and sizes of electrodes are used for different types of welds and materials, and welders develop preferences based on welding style and project.

- TIG uses an torch with a tungsten electrode. Argon is used as a shielding gas to protect weld and tungsten. An arc is struck between the tungsten and the work and a short gap is maintained. As the weld progresses, filler wire is dipped in the weld pool. Power source is constant-current DC or AC depending on metal used.

- Flux-cored Arc Welding is a welding process similar to GMAW, in that it uses a continuously fed electrode, but uses a tubular wire filled with flux instead of a solid wire. There are two types of flux-cored wire, self-shielded and dual shield.IG-Gas Tungsten Arc Welding (GTAW). Gas Tungsten Arc Welding, commonly called TIG or Heliarc, is a welding process that uses a non-consumable tungsten electrode to heat the base metal and to create a molten weld puddle.

TIG Welding What separates TIG welding from other welding procedures is the way the arc is created and how the filler metal is applied. Although this particular process is slower than others, when done correctly, it can produce a stronger, more durable weld.

Gas tungsten arc welding Meredith named the process Heliarc because it used a tungsten electrode arc and helium as a shielding gas, but it is often referred to as tungsten inert gas welding (TIG); in parts of the world where tungsten is called wolfram, it is known as WIG.he use of any shielding gas containing an oxygen compound, such as carbon dioxide, quickly contaminates the tungsten electrode, making it unsuitable for the TIG process. In 1953, a new process based on GTAW was developed, called plasma arc welding.

- If your metal is clean, no sparks will be produced as you weld. TIG welds can be made in all positions, including flat, horizontal, and overhead. No smoke or fumes should be produced as a result of TIG welding. If smoke or fumes occur, you may need to clean the metal more thoroughly.

Stainless Steel MIG Welding with Compact Welders Therefore, the recommended shielding gas to use for short circuit stainless steel MIG welding is a tri-mix shielding gas, such as 90%He/7.5%Ar/2.5%CO2. The high thermal conductivity of helium helps provide a flatter weld bead and good fusion into the base plate.herefore, you do not want to use a completely inert shielding gas, such as 100% helium or 100% argon for stainless steel MIG welding. The arc characterisitcs would be poor.

TIG IT: How a TIG Welder Works and When to TIG Weld When TIG welding steel, use a filler material, or filler rod, similar to the filler rod used in oxy-acetylene welding. It has a thin copper coating to inhibit rusting. I've been told by welding professionals that the copper coating is not detrimental to the welds even on chrome-moly.

Selecting The Right Tungsten - A Critical Issue To Get The Full Benefits of AC TIG Inverter Welding If you're welding aluminum or magnesium and choose an AC inverter, but you make the wrong tungsten selection, you won't get the maximum benefits from the advanced squarewave technology. And it will cost you money in the long run.

- TIG is a commonly used and accepted slag term. The proper terminology is “Gas Tungsten Arc Welding” or GTAW. This is the term used by welding engineers on blueprints, and in welding procedures. When TIG was introduced around the 1940’s it used to be referred to as “HeliArc” because the shielding gas used was helium.IG is a commonly used and accepted slag term.

Difference Between MIG and TIG Welding MIG vs TIG Welding. MIG and TIG welding are two types of arc welding, using metal electrodes and an inert gas as the shielding from oxidation at high temperatures. Both types of welding are relatively easy to learn, and the welding processes can be performed on all the common materials.

Comparing Welding Types: TIG vs. MIG vs. Stick vs. Arc TIG, Heliarc or GTAW (Gas Tungsten Arc Welding) is a welding process where a non-consumable tungsten electrode is used to heat up the material and melt it, creating a weld puddle. Unlike GMAW, the weld is produced from a single metal type, because there is no filler metal used for the weld.

HOME > WELDING > Mig Welding AluminumMig Welding Aluminum Because 100% argon can be used to TIG weld all metals and thicknesses you only need one type of gas in your shop to handle all of your welding projects. MIG welding aluminum is different than welding steel when it comes to shielding gas requirements. For aluminum, 100 percent argon is the gas of choice.
