Abstract:The composition and microstructure of the diamond saw blade joint welded by laser welding were studied using X-ray diffraction and SEM, and the mechanical properties of welded joint were measured. The results showed that the welding properties are affected by the composition of segments, the composition and microstructure in welding seam are strongly affected by the beam alignments.
Key words: diamond saw blade; laser welding; composition; microstructure
