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.
