Which polarity (straight or reverse) gives better penetration in DC welding?
Can you tell me some of the advantages and disadvantages of using reverse polarity in DC welding?
Sure. Some advantages of using reverse polarity in DC welding include better penetration, lower heat input, and increased deposition rates. However, using reverse polarity also increases the risk of electrode sticking, wider and more convex bead shapes, and greater spatter and fumes.
