The American Welding Society (AWS) categorizes welding positions to standardize certification testing and production procedures.

The number "3" designates the vertical position, meaning the workpiece is oriented vertically. 3f welding

| Defect | Cause | Fix | | :--- | :--- | :--- | | | Moved too fast across center; too much angle upward. | Slow down. Pause longer on the sides. | | Overlap / Cold Lap | Travel speed too slow; puddle rolling over without fusing. | Increase heat (amperage) or speed up slightly. | | Excessive Sagging (Drip) | Too much heat; puddle too large. | Reduce amperage; use a smaller electrode; pause less in center. | | Slag Inclusion (Stick/FC) | Slag ran ahead of the puddle. | Keep arc on leading edge; use a slight drag angle. | | Slow down
