High Efficiency Overlay-TIG Welding by Using ERNiCr-3 and ERNiCrFe-7
This paper introduces the high efficiency mechanical overlay-TIG welding technology by using ERNiC-3 and ERNiCrFe-7 welding wires,and compares the welding seam formation and property of the two kinds of welding wires.Basing on the traditional hot wire overlay-TIG welding,this study optimizes the welding process parameters while considering swing motion of the welding head,so as to improve the efficiency of overlay welding while ensuring welding quality.
