new product drawings are drawn, the welding sequence and welding procedure regulations must be formulated by the welding engineer or welding supervisor.

after distribution to the workshop, the monitor shall organize the workers to be familiar with the process and solder joints, and mark and number each weld, including various pre-welding preparations (such as preheating, etc.). It is best to mark it in a conspicuous way on drawings or objects.
