How TiG welding procedures are used for Mild steel

Mild steel is a steel alloy to facilitate has a low percentage of carbon, normally 0.3 percent or less. For this basis, mild steel is also called low-carbon steel. It is enormously common in manufacture because it is inexpensive compare with other steel alloys and is simple to weld. Mild steel can be welded with tungsten inert gas (TIG) welding methods, and the result is a clean and precise weld.

For the reason that the TIG welding process uses a tungsten electrode that is not consumed, a divide welding rod or wire is used as filler material for welding mild steel.

Steel require a sharper electrode point to concentrate the heat at the weld seam, as different to aluminum and other metals, in which heat dissipate more rapidly. The diameter of the electrode should be approximately half the thickness of the parts to be welded. The welding machine must be set for DC current and directly polarity, through the electrode having the negative charge.
