In uphill 5G, you weld the right side 6→12, then reposition and weld the left side 6→12. welding 5g position
Depending on the Welding Procedure Specification (WPS), welders typically use vertical-uphill (bottom-to-top) for deep penetration or vertical-downhill (top-to-bottom) for faster production on thinner materials. | Position | Pipe orientation | Rotates
