The effects of laser welding parameter on strength of welded joints were studied. The mechanism for loss of joint strength was analyzed. It was pointed out that an important factor affecting joint strength is the reaction between matrix and reinforced phase. On the basis of this, the concept of crit...

Up till now, most of the researchers believe that there are four kinds of forces in the weld pool convection, they are surface tension, electromagnetic force, buoyancy and gas shear stress. So electromagnetic force is very important, especially when large current is applied. In most of previous mode...

A three dimensional current density distribution in double-sided gas tungsten are welding (GTAW) proces is performed. The current density distribution field is evaluated by numerically solving Maxwell equations in the domain of the workpiece. In the boundary condition, the current density on the wor...
