4g Position Welding Here

Due to the difficulty of the position, specific defects are common:

The 4G overhead welding position is a rigorous test of a welder’s skill. It requires a deep understanding of heat control, excellent hand-eye coordination, and the ability to manipulate the molten pool against the force of gravity. Achieving a sound 4G weld—characterized by proper penetration, uniform bead profile, and absence of defects—is a requirement for structural certification and a hallmark of a proficient welder.

Use a leather welding hood or a fire-resistant cap under your helmet to protect your scalp and ears. 4g position welding

But ? Overhead.

In the 4G position, the weld axis is horizontal, but the welding is performed from the underside of the joint. The face of the weld is oriented horizontally, and the filler metal is deposited into the joint from above the welder’s head. This position is widely considered one of the most difficult and physically demanding positions to master due to the forces of gravity working against the molten weld pool. Due to the difficulty of the position, specific
