CMT is a welding process by Fronius that changes the game for anyone working with thin sheet metal, aluminium, or applications where post-processing simply takes up too much time. The principle is clever. the welding wire doesn't just move forward, it's also actively retracted the moment a short circuit occurs. This happens at a frequency of up to 170 times per second. The result? A stable arc, minimal heat input, and virtually no spatter.

Suitable for

CMT is a versatile process that suits a wide range of applications, including joint welding on stainless steel, overlap welding, aluminium welding including sheet thicknesses down to 0.3 mm, galvanised sheet metal, root welding, and brazed joints.

We find that the CMT process is a strong alternative to TIG welding with a cobot. With CMT, the wire feed is fully integrated into the Fronius CMT torch. With TIG cobot welding, an external cold wire feeder often needs to be added, which complicates both the programming and the freedom of movement of the cobot.
