The influence of heat treatment on properties of three-metal explosion joint: AlMg-Al-Steel

The procedure of welding by explosion is as technical optimal solution of ship-shell parts joining frequently used in shipbuilding industry at transition three-metal joint: AlMg4.5-Al-St.52-3 working out. The investigations of mechanical and metallographic properties of joints, exposed on heat treatment at different temperatures levels, are performed. The results of mechanical and metallographic examinations of transition joints at elevated temperatures, direct on its use below 300 °C. The additional melting welding working out is in closeness of explosion- welded joint allowed.
