6063 Aluminum Alloy

Tensile shear strength and ageing treatment of dissimilar 6063 aluminum alloy-316L stainless steel joint fabricated by spot welding were investigated. The results showed that tensile shear strength increased with the increasing of welding current. The enhancement of tensile shear strength of the joints was due to the enlargement of the nugget diameter. It was also found that the tensile shear strength values for heat treated joint almost similar to that of non-heat treated joint.

In this paper, friction stir welding (FSW) was used to weld the dissimilar A6063 Aluminum/SUS430 stainless steel lap joint with various parameter setting in a welding process. The setting included a rotating speed between 125-750 rpm, a welding speed between the 25-175 mm/min and 0-5 degrees of tool tilted angle. The welded lap joints were systematically examined in regard of the tensile-shear strength, the fracture path, and microstructure. The experimental results were concluded as follows. The decrease in the welding heat input generated from the low rotating speed and the high welding resulted in decreasing of the shear strength. A degree of a tool tilted angle affected a shear strength, and a change in the strength came from the different rate in material combination at the joint interface. The increase in a tensile-shear strength occurred for specimens produced in 0-2 degrees of a tool tilted angle while 3-5 degrees affected in decreasing. The highest shear strength of 11,870 N was obtained when the lap joint was produced by the rotating speed of 500 rpm, the welding speed of 50 mm/min and the tool tilted angle at 2 degrees. The fracture path found in the specimen with the maximum shear strength was located in the Al stirred zone, not in the joint interface.

The Reformation

The shear strength of 302 austenitic stainless steel spot welds has been studied. Thewelding current in resistance spot welding process (RSW) plays a significant role. However,this item's effect is well known and extensively studied in the previous literature. This work aims toshow the heat treatment’s effect on different joints that welded at various current. The experimentalresults show that the tensile shear strength is increased with increasing the current. Annealingtreatment improves the tensile shear strength due to the reformation of the grain size and removesthe residual stresses. Grain refinement is an effective technique for improving the strength.Therefore, the tensile shear strength is increased by annealing treatment temperature up to 750 °C.However, at 850°C, the tensile shear strength is dropped down.
