The 4G overhead welding test is widely considered one of the most difficult welder qualification tests due to the physical demands and the need to combat gravity. Success requires a combination of correct machine settings (lower amperage), precise body positioning, and steady hand-eye coordination.
This report outlines the parameters, safety requirements, procedure, and evaluation criteria for a standard 4G certification test, typically performed on carbon steel plate using the SMAW (Stick) process. 4g weld test
