  • Cold Metal Transfer - Wikipedia

    Cold Metal Transfer (abbreviated CMT) is a welding method that is usually performed by a welding robot. The CMT machine detects a short circuit which sends a signal that retracts the welding filler material, giving the weld time to cool before each drop is placed. This leaves a smooth weld that is stronger than that of a hotter weld.
