Abstract:Cold metal transfer (CMT) and gas metal arc welding with pulsed current (GMAW-P) were used to apply a hardfacing layer on AISI 1045 steel plates with EnDOTec DO15 ller wire. Three conditions were studied for the plates with hardfacing; as welded (AW), annealed (ANN) after welding for minimum hardness and tempered heattreated (HT) after welding targeting hardness values of ~ 400 Vickers units. For the same metallurgical condition, there were no noticeable variation in the microhardness values despite the weldin… Show more
