A weld is what is needed in welding processes; as for weld scars, just search for \"weld beads\" and you’ll understand
Weld scar phenomenon: Failing to remove weld scars after welding affects the overall quality of the equipment; improper handling can also lead to surface cracks. Reason: It is caused by the positioning welding fixtures used during the manufacturing and installation of non-standard equipment, which remain in place after completion. Prevention and control measures: The lifting fixtures used during assembly should be ground with a grinder to make them level with the base material after they are removed; it is not advisable to use a sledgehammer to remove these fixtures, as this could damage the base material. Any deep arc pits or scratches resulting from welding must be rewelded, and then ground to be level with the base material. By being careful during operations, such defects can be eliminated.
