Welding type - Tig welding process，Arc Welding

The Tig Welding Process

Stands for Gas Tungsten Arc Welding (GTAW) or more commonly Tungsten Inert Gas process (TIG)

Learning how to Tig weld is more difficult than the mig process as the operator must control the welding torch and the filler material simultaneously. The process involves an arc being struck to the work using a tungsten electrode in the hand-piece, filler material is then applied through the resulting arc. In some instances such as sheet metals no filler rods are used as the join is simply fused together using the arc. Obviously this requires a neat joint without gaps--Sale Of Welding Positioner.

Tig welds preformed properly will give an outstanding quality finish with high strength. They require minimal clean up as there is no slag or soot to deal with. Most effective for welding stainless steel and aluminum sheet metals, pipe work and products needing a neat tidy finish.

Arc Welding.

Next to gas the Arc welding process is the oldest of welding processes. Still used extensively in industry and for home use learning how to arc weld is a somewhat easier process. However having said that the application of the process can be complicated in the choice of welding electrodes. Arc weld electrodes have a flux coating that generates a shielding gas to protect the metal from atmospheric contaminants, they increase deposition rates and covers the weld with a slag coating. There are many specialist electrodes available such as for hard facing and pipeline welds that are required to have x rays for quality--Sale Of Welding Positioner.

Arc welding can be used for welding mild steel, hardened steels, stainless steel, cast iron and numerous specialty steels. Slag deposits require removal so some clean up is needed. Various electrodes require more or less clean up.

As arc welders do not require an external gas resource they are ideal for outdoor and site work, and are widely used in maintenance and construction work--Sale Of Welding Positioner.
