ABSTRACT
The paper and talk deal with the research results in the field of welding the combined
metals such as Ti-Cu, Ti-Al, Sn-Cu, Al-Mg alloy, Monel-steel, Pb-steel, AlSi alloy-Cu,
Ta-Monel, Ta-Stainless Steel, Monel-Ta, steel-Ti-Al, steel-Cu-Al, etc., as well as the
processes allied. The combinations that are not mentioned in the paper will be
presented during the talk.
The results were attained in collaboration with the Research Institute of Industrial
Chemistry, Pardubice-Semtin (Czech Republic) and the Slovak University of
Technology, Department of Welding, Faculty of Materials Science and Technology,
Trnava (Slovak Republic). The bimetals and trimetals were produced using the Semtex
S explosive. The quality of joints was evaluated by ultrasonic detection, optical
microscopy, microhardness measurements and X-ray microanalysis.
