Cold Metal Transfer (CMT) is a welding technology that is an advanced variation of gas metal arc welding (GMAW). CMT is characterized by its ability to produce low-heat, high-quality welds with minimal spatter and distortion. It is particularly effective for joining thin materials or materials that are sensitive to heat, such as aluminum and certain high-strength steels. The CMT process involves a unique interaction between the welding wire and the workpiece during the welding arc's operation.
