The article presents issues related to arc braze welding of tubes made of 10CrMo9-10 (10H2M) boiler steel lined inside with copper. In addition, the study points to possibilities of producing joints using conventional and innovative welding methods as well as presents results of radiographic, metallographic and mechanical tests (static tensile test, technological bending test, hardness measurements) of braze welded joints made using a robotic braze welding stand and the CMT (Cold Metal Transfer) method.
