7 Types of Welding Processes | The Welding Pro
During the welding, gases such as helium or argon (inert gases) are streamed to protect the electrode, the base metal, the weld pool, and the arc from interacting with the air in the surrounding. To produce the desired weld parameters such as wire feed speed, arc current and voltage, temperatures during preheating, the density of the current, and the rate of electrode travel should be considered.
