摘要
激光焊接的快速加热及快速冷却特性决定了焊缝的成分及组织的不均匀性,由此导致了产生各种焊接缺陷的可能性。本文利用扫描电镜分析了金刚石锯片激光焊接过程中出现的主要焊接缺陷,如:气孔、裂纹、夹杂物。此外,还对抗弯强度试样的断口进行了分析。
Due to the higher heating and cooling speeds of laser welding,both microstructure and composition in the welding seam are inhomogeneous,which might generate the possibilities of some kinds of defects.The defects in the welded seam of diamond saw blade by laser welding,including pores,cracks and inclusions,were studied by using SEM.Additionally,the fracture surfaces of bending strength specimen were also explained.
