The paper presents a discussion on the issue of thermal efficiency of the process of superficial remelting of castings by means of the gas tungsten arc welding (GTAW) process. Described and characterized are calorimeters used in research studies on efficiency of welding processes and the obtained results. Example results are presented from the measurements aimed at determination of thermal efficiency of the welding process carried out with the use of the flow calorimeter.
