Description
Explosive welding block, also known as bimetal, Al-St insert, bi-metallic, tri-clad, electrical transition joint, is widely used in electrolytic aluminum industry and metallurgy industry.

The new explosive welding method integrates with pressure welding, fusion welding and diffusion welding.

This method can successfully welds the metals which have different intensity, expansion coefficient and performance.

The different performance of base metal and cover metal can be rationally combined and matched, and the noble metal can be saved to minimum amount.

Explosion cladding is a solid state welding process that uses precision explosions to bond two dissimilar metals while retaining the mechanical, electrical and corrosion properties of both.

The process is most commonly used to clad steel with a thin layer of corrosion-resistant alloy metal, such as aluminium, stainless steel, brass, nickel, silver, titanium, or zirconium.

However, explosion welding can join a wide array of compatible and non-compatible metals; with more than 260 metal combinations possible.

The explosion weld is achieved in milliseconds; therefore, no bulk heating occurs, and the metals experience no dilution. Our clad can deliver high shear strength and high tensile strength.
