Effect of Various Heat Sources on Heating of Contact Tip during Mig/Mag Welding

Abstract

Various heat sources effect on the contact tip of the welding torch for MIG/MAG welding has been considered. Factors affecting heating rate and contact tip temperature during welding have been described. Experiments on heating rate and contact tip temperature for various welding conditions have been presented. Sources of heat, exerting maximum influence on contact tip heating have been identified.
