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 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 influence of interfacial reaction on crack initiation and propagation in Ti/Al joint by laser welding-brazing (LWB) was investigated to obtain strong joints.

TL;DR: In this article, the experiments of CO2 laser TIG paraxial hybrid welding with 4 mm thick AISI 321 stainless steel sheet have been performed and the arc images and welding characteristics have been investigated with different energy ratios between laser and arc.

TL;DR: In this article, the Si diffusion behavior has a significant effect on the formation of interfacial intermetallic compounds and a model for the prediction of the chemical potential for ternary alloy was established.
