Micro Welding

There is no concrete definition of what constitues a micro weld.  At Amada Miyachi, however, in general, a resistance welding application is considered to be a “micro weld” if it has wires less than .005” diameter, or ribbons less than .004” thick, which can be welded with less than 500 Amps of current.

In laser welding applications, anything requiring less than 0.04” weld penetration is considered a micro weld.

And for more information about the resistance welding process read our Fundamentals of Resistance Welding and visit our UB29 micro welding machine product page.
