Current (Weld)

The amount of electric charge flowing past a specified circuit point per unit time Current is the main parameter for welding and has to be chosen to plate thickness and welding speed with respect to the weld quality. The weld current affects penetration and deposition rate. A high current results in a higher and narrower weld with a greater penetration depth. Too high a welding current can result in undercuts, an uneven weld convexity, burn-through, thermal cracking, an inappropriate merging angle with the body material and undercutting.
