Tack welding is a crucial technique used to hold workpieces in place temporarily before applying a permanent weld. It helps maintain proper alignment while preventing distortion, warping, and overheating. To achieve optimal results, small tack welds are recommended, typically ranging from one-half to three-fourths of an inch in length, with a maximum length of one inch. These controlled welds ensure structural integrity during the fabrication process while preserving the aesthetic quality of the final piece.1
