Explosive welding block also known as bimetal, cladding, electric transition joint, widely used in electrolytic aluminum industry and metallurgical industry.Explosion welding block is to use the welding method and processing of metal composite materials, as a kind of new welding technology, explosion welding set pressure welding, fusion welding, diffusion welding, can make the strength difference, different expansion coefficient and no melting performance of various kinds of metal welded together, saving precious metal, to facilitate the performance of the cladding material and base material reasonable combination and matching.


Aluminum -Steel Explosive welding block (sheet) is made of aluminum/steel nonferrous metal series explosive compound, widely used in electrolytic aluminum, metallurgical industry.Aluminum steel explosive welding blocks are divided into cathode explosive welding blocks and anode explosive welding blocks.It is a conductive transition device in the process of making electrolytic cell in electrolytic aluminium factory.Aluminum steel explosive welding block in the electrolytic cell as a kind of aluminum and steel transition joints, aluminum bus bar and steel bar close together, play a transitional role, also due to the explosive welding interface is metallurgical combination between atoms, so the interface resistance compared with the mechanical connection, negligible, it can not only save energy consumption and prolong the service life.
