Abstract : This report describes the development of manufacturing methods for gas tungsten-arc (TIG) welding of 5/8 in. and 1 in. thick 18% Ni Maraging steel plates. High currents densities were used to increase the depth of arc penetration and also the speed of welding. High filler wire deposition rates were attained without or with preheating of filler wire for both flat and horizontal welding positions. Consideration was given to the transferability of the process to production conditions and arc penetration control system was used in producing final welds to better than 95% joint efficiency.
