Summary of the
CMT process
CMT = Cold Metal Transfer
A special CMT drive unit is required for the CMT process.
The reversing wire movement in the CMT process results in a droplet detachment with im-
proved dip transfer arc properties.
The advantages of the CMT process are as follows
- Low heat input
- Less spattering
- Reduced emissions
- High process stability
The CMT process is suitable for:
- Joint welding, cladding and brazing – particularly in the case of high requirements in
terms of heat input and process stability
- Welding on light-gauge sheet with minimal distortion
- Special connections, such as copper, zinc, and steel/aluminium
NOTE!
A CMT reference book is available complete with typical applications; see
