In light of the property of the steel-aluminum structural transition joints,several problems in the welding of steel-aluminum structure transition joint in the high-speed ship are analyzed from the view of mechanical behaviour,welding parameters and anti-corrosion capacity.

Extrusion Casting Technology for the Aluminum Alloy Joint;

At the same time, using the micro-shear test result to study the micro-performance changes in natural aging of several Al-alloy joints,and the influence of Al-alloy joint by welding parameters.
