What is a TIG welder good for?
TIG stands for Tungsten Inert Gas and is technically called Gas Tungsten Arc Welding or GTAW. The process uses a non-consumable tungsten electrode that delivers the current to the welding arc. The tungsten and weld puddle are protected and cooled with an inert gas, typically argon.
The major difference between Mig and Tig welding is that one process uses a continuously feeding wire (MIG) and the other you use long welding rods and slowly feed them into the weld puddle (TIG). The technical names for these are metal inert gas (MIG), and tungsten inert gas (TIG).
- No Gas MIG Welders. No gas mig welders, also known as a flux core wire welder, is a simple process for beginners to learn how to weld with. The awesome thing about no gas MIG welders is that you can start welding right out of the box when you buy a new wire welder. A wire welder is also known as a MIG welder.
- TIG welding produces quality welds. While costing more than MIG or stick-only welders, a single TIG/stick machine gives the user great flexibility. Shielded Metal Arc Welding (Stick) This process uses a consumable, flux coated electrode containing mild steel, stainless steel, cast iron or various other alloys.
- MIG welding is clean, easy and can be used on thin or thicker plate metals. Similar to MIG welding, flux-cored arc welding (FCAW)* is a wire-feed process but differs in that self-shielded flux-cored welding does not require a shielding gas. Instead, flux-cored wire is used to shield the arc from contamination.
Helium is also commonly used to weld stainless steel and copper. The argon/helium combination gas is used for a hotter arc in welding aluminum and aluminum alloys. It is also used in automatic welding applications. Even though TIG is a commonly used welding process, there are a number of limitations.
- MIG welding is useful because you can use it to weld many different types of metals: carbon steel, stainless steel, aluminum, magnesium, copper, nickel, silicon bronze and other alloys. Here are some advantages to MIG welding: The ability to join a wide range of metals and thicknesses. All-position welding capability.
- TIG can be used to weld copper, titanium, even two dissimilar metals, and is handy for making tricky welds (e.g. s-curves, or welds on round things).. TIG generates heat via an arc of electricity jumping from a (tungsten metal) electrode to the metal surfaces you intend to weld - usually aluminum or steel.
- Shielding gases for TIG/GTAW welding. The normal gas for TIG welding is argon (Ar). Helium (He) can be added to increase penetration and fluidity of the weld pool. Argon or argon/helium mixtures can be used for welding all grades.
The average salary for a Tig Welder is $18.68 per hour in Texas, which is 8% above the national average.
- To answer this question – at least in America – I turn to the BLS. Their data records topside welder income. The average welding salary is $18.45 an hour according to average wage statistics, with yearly salaries at $33,380. The top 10% of welders make $26.10 an hour and the bottom 10% make $12.05.
- COMBINATION WELDER. DEFINITION. Under supervision, constructs, modifies and repairs a wide variety of metal parts using oxyacetylene, arc or heliarc welding apparatus; assists in mechanical and structural repairs to equipment and facilities; and does related work as required.
- A pipefitter is a tradesperson who installs, assembles, fabricates, maintains and repairs mechanical piping systems. Pipefitters usually begin as helpers or apprentices.
