inhomogeneous microstructure appeared in the thickness direction of laser-MAG hybrid weld. Herein, the microstructure homogeneity … inclusion distribution of the weld became homogeneous, the microstructure became homogeneous in the thickness direction, and a … mixed microstructure of acicular ferrite and lath martensite was obtained. The large-angle deflection of the main crack …
