This work presents results of investigation the C90U steel surface remelting with a concentrated energy beam, using the GTAW method. The top surface layer of the C90U steel was partially remelted at the welding head feed rate of 200 mm/min, and the electric arc current of 50 through 300A. Microscopic inspection of resulting structure, as well as remelted layers' geometry and hardness measurements were conducted. The correlation between electric arc current and the remelted layers' geometry, microstructure and micro-hardness was derived. In the remelted zone, numerous inter-crystalline cracks were found with the current intensity of 200 and 300A.
