Comparative Assessment of Composite Materials Performance Subjected to Fillet and Butt Welding

Abstract:

This study presents a comparative assessment of composite materials performance, based on 80%Al+20%CrC, 82%CuNiAl+18%WC and 82%CuZn48+18%CrC, butt welded and corner welded. This comparative assessment resulted in information regarding the chemical content of the welded joints in percent, macro-microstructure estimation of specific areas of the welded edge joints, and determination of HV5 hardness of specific areas of the welded joints, both for butt welding and corner welding. It was shown that there is a slight variation of chemical composition both for butt welding and corner welding. Also all nanostructured composite materials, butt welded and corner welded, examined for macroscopic and microscopic examinations showed no welding defects. After testing the HV5 hardness of specific areas of butt and corner welded joints, made using WIG and CMT welding processes, the estimator value for structural hardening ΔHV5 between specific areas (WELD, HAZ, BM) was determined.
