4f Welding Position Full [upd] Now

For larger fillet welds (e.g., 10mm leg length), multiple passes are needed.

. This means you are joining two pieces of metal at a right angle—like a T-joint—where the joint is situated above your head and you are welding on the underside. Unlike flat or horizontal welding, where gravity helps seat the puddle, 4F requires you to literally "push" the metal into the joint and keep it there. The Core Challenges Gravity vs. Puddle Control: 4f welding position full

It is critical to distinguish 4F from . While both are overhead, the joint geometry changes everything: For larger fillet welds (e
