Abstract

TIG welding experiments have been used for the welded joints of the austenitic stainless steel and molybdenum. The aim of the experiments was to find the optimal welding parameters. The problems that occurred throughout the welding process were due to the very high melting point of the Mo. Also, using optical microscopy and scanning electron microscopy have performed a proper testing in parallel with the experiments. Regarding to the wear of electrode, there have been determined the tip angle, the tapering and the effect of the electrode’s material composition. The latter parameter was investigated for thorium-oxide and lanthanum-oxide alloyed electrodes.
