If you’ve spent any time in a fabrication shop or working toward a structural welding certification, you’ve heard the term "4G." Simply put, the position is where theory meets reality. It is widely considered the second hardest position (next to 6G pipe), but arguably the most physically demanding for plate and structural steel. 4g welding position
Rating: ⭐⭐⭐⭐ (4.5/5 – Extremely Challenging but Essential) It is widely considered the second hardest position
Holding a 30lb stinger or a heavy MIG gun above your head for an 8-inch weld while craning your neck to see through a dark lens is exhausting. Your triceps will burn, and your neck will lock up. It is impossible to get "comfortable" in 4G; you only get "less uncomfortable." It is impossible to get "comfortable" in 4G;
If you plan on repairing heavy equipment (under a dozer), welding trailer hitches while lying on a creeper, or fixing a pipe rack in a refinery, you will live in 4G. It simulates field conditions perfectly. The Bad: The Physical & Mental Toll 1. The "Rain of Fire" (The biggest con) I cannot stress this enough: Spatter has to go somewhere. In 4G, that somewhere is your neck, your gloves, your pockets, and your boots. Even with a leather jacket and a skull cap, hot slag will find a way inside your collar. You will leave a 4G test booth smelling like burnt hair and regret.
