About Microwelding

Microwelding is a relatively new, highly specialized welding process by which metals are re-formed or joined together using a low amperage power supply, a miniature electrode pointing system, small diameter welding wire and a customized microwelding microscope. The chief technical advantages of microwelding include low heat production and precision placement of weld material. One of the leading applications of microwelding is in tool, die and mold repair. Tools, dies and molds are precision products used in close tolerance manufacturing processes. They are constantly subjected to the repeated stress of the manufacturing environment and regularly sustain nicks, gouges, scores and cracks that require maintenance, repair, or, in some cases, complete replacement. Prior to the advent of microwelding, manufacturers were forced to choose between unsatisfactory repairs and/or costly replacement of molds. Both choices caused unacceptable levels of production downtime. Microwelding has provided manufacturers with an excellent cost saving alternative. It has proven to be an efficient, cost effective method to repair and extend the life of tools, dies and molds without compromising manufacturing quality. Additionally, the higher efficiency of microwelding significantly reduces downtime, particularly if the manufacturer has in-house microwelding capability.
