AI Technical Summary
When existing explosive welding blocks are used in electrolytic aluminum baths, the welding area is fixed, the current throughput is limited, the energy consumption is high, the structural strength is generally low, the probability of brittle phase formation at the interface is high, and the fixed contact area results in general strength.
A nickel layer is placed between aluminum and steel plates, and explosive welding is performed between the plates. The aluminum plate is connected to the nickel layer, and the nickel layer is connected to the steel plate through the nickel layer. Through grooves and welding grooves are opened in the middle of the aluminum and steel plates. The surface of the steel plate is set with protrusions and pits, and the edges are wrapped with a soft metal frame.
The ductility of the nickel layer buffers the explosive impact stress, reduces the probability of brittle phase formation at the interface, increases welding strength and conductivity, improves welding area and stability, avoids stress concentration, and enhances bonding depth and conductivity.
