The aluminum-steel transition joint is a three layered explosively bonded material, generally composed of aluminum alloy, pure aluminum and steel, of which the pure aluminum layer is the intermediate transition layer. In the aluminum-steel transition joint obtained by the explosive welding method, the metallurgical bonding between the various layers of metal ensures the high strength of the joint.

Aluminum steel transition joints installation process:

The aluminum steel clad plate is composed of three layers of different material structures. The base layer is welded with the marine joint steel, the composite layer and the aluminum alloy plate are welded, and the intermediate layer plays a role of transitional connection. The base layer of the aluminum steel clad plate is directly welded to the steel main hull deck for constant-current welding of carbon dioxide gas. The aluminum alloy steel joint aluminum alloy superstructure is directly welded to the aluminum alloy superstructure by argon arc welding. Because the aluminum steel transition joints needs to be welded together with the aluminum alloy superstructure and the steel deck of the marine joint, the welding process needs to meet the welding process requirements of aluminum alloy argon arc welding and carbon dioxide gas shielded welding. Welding of different materials should use different welding equipment and welding parameters to ensure welding quality. Before welding, it is necessary to do a good job in preparation of joint scribing, assembly and positioning, and grinding and rust removal. During the welding process, the welding voltage, current, and welding speed are strictly controlled to ensure the quality of the weld.
