Comparison of CMT with other arc modes for laser-arc hybrid welding of steel [PDF]

, 2014
In this study, three different arc modes in laser-arc hybrid welding with a gas metal arc were studied, i.e. the standard, pulsed and cold metal transfer (CMT) modes. The pulsed mode is more controlled than the standard mode and offers reduced heat input
