Why TIG welding is used?
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.
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).
- 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.
- Carbon Dioxide (CO2) is the most common of the reactive gases used in MIG welding and the only one that can be used in its pure form without the addition of an inert gas. CO2 is also the least expensive of the common shielding gases, making an attractive choice when material costs are the main priority.
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.

- Arc welding uses an electrical arc to melt the work materials as well as filler material (sometimes called the welding rod) for welding joints. Arc welding involves attaching a grounding wire to the welding material or other metal surface. Another wire known as an electrode lead is placed on the material to be welded.

The average salary for a Tig Welder is $18.68 per hour in Texas, which is 8% above the national average.
- The average salary for welders is $36,720, which is a pretty typical middle class welding job. However, welding jobs will bottom out around $25,000 a year, which may be common for many entry-level welding positions. On the other hand, the 90th percentile of welders earn around $57,000 a year.
- 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.
- A boilermaker is a trained craftsperson who produces steel fabrications from plates and tubes. The name originated from craftsmen who would fabricate boilers, but they may work on projects as diverse as bridges to blast furnaces to the construction of mining equipment.
