TL;DR: In this paper, the microstructures of fusion welding and brazing zones were analyzed in details by transmission electron microscope (TEM) and it was found that fusion welding zone consist of α-Al grains and ternary near-eutectic structure with α -Al, Si and Mg 2 Si Interfacial reaction layers of brazeling joint were composed of α -Ti, nanosize granular Ti 7 Al 5 Si 12 and serration-shaped TiAl 3

TL;DR: In this paper, the effect of laser-beam offsetting on microstructural characteristics and fracture behavior of the joint was investigated and it was found that when the laser beam is offset toward the stainless steel side, it results in a more durable joint.

TL;DR: In this paper, the microstructures and mechanical properties of stainless steel/copper laser welding were investigated by controlling the processing parameters of welding speed and laser power as well as the offset and incline angle of the laser beam in the direction of the stainless steel.

TL;DR: In this paper, the effect of laser welding and V-shaped groove on the nonhomogeneity of interfacial reactions was investigated by finite element method (FEM) numerical simulation and experimental validation, and the results indicated that the Vshaped groove can make the interface roughly parallel to the isotherm of the temperature field and further improve homogenization of the interfacial reaction along the interface in comparison with circular spot laser.

TL;DR: In this article, the effects of the content of short carbon fibers, brazing temperature and holding time on the shear strength and microstructure of the brazed joints were investigated.
