The 2G preset is used to offset distortion caused by what welding condition?

• A. Multiple stringer beads
• B. Single stringer beads
• C. Warping of the base metal
• D. Poor fit-up joint

Answer: (A)

Managing how heat input causes the metal to shrink as it cools is what this is about. When you lay down several stringer beads along a joint, each pass concentrates heat in a different spot. As the weld cools, the metal contracts and the repeated cycles pull the plate in various directions, which can bend or warp the workpiece. A 2G preset is a deliberate offset applied to the welding path to counter that predictable distortion pattern from multiple passes. By offsetting the bead placement, the net effect after cooling keeps the joint straighter. With a single stringer bead, distortion is much less and a specific offset isn’t as necessary. Warping and poor fit-up are related issues, but the preset’s purpose is specifically to compensate for the cumulative distortion that comes from using multiple stringer beads.
