Arc welding using the Metal filler wire as consumable electrode and an Inert Gas to protect the molten pool against oxidation. Figure 1. Schematic of the MIG welding process. In the metal inert gas ...
In the tungsten inert gas (TIG) welding process, an electric arc is struck between a refractory electrode made of tungsten and the work piece, while a shroud of inert gas, usually argon, shields the ...
Welding fumes are very small particles that are formed when the vaporized metal rapidly condenses in air. They are typically too small to be seen by the naked eye but collectively form a visible plume ...
