Abstrakt

The paper presents the results of qualitative tests of Cu-Al joints made by soldering, brazing and resistance welding. Aluminum and copper tubes with a diameter of 6.9 mm, used, among others in refrigeration systems, were soldered with ZnAl2 and AlSi12 filler metal. In addition, similar connections were made by resistance welding. Macroscopic tests of soldered and welded joints were carried out and the hardness distribution on the cross-section of joints was determined. The analysis of research results allowed to state that resistance welding of Cu-Al joints can be a good alternative to the soldering process, especially in series production, due to the possibility of easy application of process mechanization.
