Welding Test of Marine Aluminum Alloy-titanium-stainless Steel Composite Transition Joint

Through non-destructive test after welding, interface bonding strength test and organization observation, aluminum alloy-titanium-stainless steel composite transition joint welding process was investigated. The results show that after welding, the microstructure and properties of aluminum-titanium-stainless steel transition joint are in accordance with the relevant technical regulations, which provides some references for the engineering application of aluminum-titanium-stainless steel composite transition joint.
