CMT WELDING MACHINE

There are some materials and applications where having only a low thermal input is extremely beneficial: By making it possible to weld seams without root-side dropthrough, for example, or perform spatter-free brazing, or even make certain types of joins which used to be either problematical or right out of the question. With CMT, all this is now perfectly feasible. CMT stands for Cold Metal Transfer. Of course, the term “cold” has to be understood in terms of a welding process. But when set against the conventional MIG/MAG process, CMT is indeed a cold process. Its characteristic feature: hot, cold, hot, cold, hot, cold. This alternating hot & cold treatment has been made possible by a new technological development from Fronius. And above all, by incorporating the wire motions into the process-control. The result: Spatter-free MIG/MAG robot welding and brazing for ultra-light gauge sheets from 0.3 mm (0.012"). In either automated or manual applications. But let’s take one thing at a time.
