Quizplus · Accepted Answer

Technician A is correct because using a stitch weld technique when welding seams can indeed minimize warpage by distributing heat more evenly and allowing the metal to cool between welds. Technician B is incorrect because when drilling out spot welds, it's best to drill through the top layer only to separate the pieces without damaging the second layer, which can be useful for repairs and restorations.
