Field welding repair

Welding to repair damaged components in broken equipment involves three stages, each of which must be performed meticulously to ensure that the machinery runs properly and the repair lasts a reasonable length of time. What are these stages, and what equipment do you need to complete them?

Brazing copper and copper alloys

It is important to be able to identify when brazing is suitable for joining copper or copper alloys, how it is applied, and which filler metals to use.

Weld repair—Analyze the failure before attempting the repair

When something breaks, you acknowledge the shock, scratch your head, take stock of the situation, and look for the fastest way to repair the item and put it back into operation. The pressure to repair quickly is understandable, but common sense suggests stopping for a moment and trying to understand what caused the break before attempting the repair.
