What is CMT welding?
Cold Metal Transfer (CMT) welding is a pioneering welding technique in MIG/MAG. Unlike MIG/MAG, this welding method has a low heat input and the ability to utilise low short circuit current during the welding process. This makes the welds and solder joints virtually spatter-free, and therefore requires almost no rework.
How CMT welding works
Unlike the conventional MIG/MAG method, where the filler wire is fed continuously, CMT welding involves intermittent wire feed and retraction. When the wire touches the plate, it is pulled back slightly, giving better control over the weld. The wire is then fed forward again and the process is repeated.
Advantages of CMT welding
CMT welding offers a number of unique advantages over traditional MIG/MAG welding methods. Some of them are:
- Spray-free: Minimises spatter, saves time and provides cleaner welding.
- Low heat input: Ideal for thin materials (from about 0.3 mm).
- Stable process: Smooth and consistent weld seam regardless of material or speed.
- Higher productivity: CMT welding is faster, allowing for lower costs.
