A common mistake is using the same amperage settings used for flat welding.
: It explains how "reverse gravity" in the overhead position, combined with backward flow, increases bead height and often results in a convex-shaped bead . 4f welding position full
Not all processes are equally suited to 4F due to gravity's effect on molten metal. A common mistake is using the same amperage
: Represents the overhead position, where the weld is performed from the underside of the workpiece. combined with backward flow
