In the laser welding process using a focused Gaussian beam, high thermal gradient and
molten pool instability usually lead to coarse columnar grain, poor surface quality and …

A systematic and accurate analysis of microstructural evolution in the interlayer regions of
multilayer welded joint is of great importance for in-depth understanding of influence …

In lap joint laser welding, a common practice is to conduct trial-and-error experiments using
various parameter settings to determine processing conditions that enhance the quality of …

In this paper, the microstructure and pitting corrosion resistance of S32101 duplex stainless
steel keyhole tungsten inert gas welded joints with different heat inputs were studied. The …

The purpose of this study was to evaluate the effect of laser parameters on the fatigue crack
growth (FCG) behavior of AZ31B Magnesium alloy TIG welded bionic joints with 'soft …

In this study, a fiber laser at a wavelength of 1070 nm with different beam shapes (spot,
dough-nut, and spot-wobble) was used to weld thin 316 L stainless steel foils. The welding …

Controlling repeated thermal cycling is one of the key mechanisms to design microstructures
in the interlayer regions for narrow gap laser wire filling welding (NGLWFW) of austenite …

The interactions between laser and metal are extremely complicated, during which material
is gradually removed due to melting or evaporation. This further leads to a continuously …

The multi-pass welding of 45 mm thick 304L stainless steel is carried out by flux-cored wire
arc welding. The mechanical property of the welded joint is characterized. Residual stress …

The automobile industry relies primarily on spot welding operations, particularly resistance
spot welding (RSW). The performance and durability of the resistance spot-welded joints are …
