Shielded Metal Arc Welding Gas Metal Arc Welding: Effects of Welding Variables

Shielded metal arc welding and gas metal arc welding are two common welding processes. For both processes, there are optimal settings for variables like current, travel speed, and arc length. Settings that are too low, high, long, or short can negatively impact the quality of the welded joint. Maintaining the proper settings for variables is important for successful welding.
