Study on Effect of Gouge Depth on the Microstructure and Tensile Properties of 18%Ni Maraging Steel Welds Made Through Hot Wire GTA Welding

Ultrahigh strength maraging steels are welded by gas tungsten arc welding (GTAW) over a wide range of thicknesses. However, the speed of conventional GTAW process is limited and hence the deposition rates are less. To enhance the productivity with reduced weld defects, hot wire GTAW (HW-GTAW) proces...
