Explosion Welding

Technology for Welding Different Metals

Two or more types of metals are welded together through the use of high impact energy generated upon the explosion of explosives. Metals welded in this manner are used for a variety of purposes.

Explosives Demolition

Ecological and Safe

Compared to existing mechanical demolition methods, our explosives demolition is more cost-effective and time efficient.
It also effectively maintains the integrity of structural safety and mitigates noise, vibration and dust.

Explosion Welding(Cladding) A Technology for Welding Different Metals Two or more kinds of metals are welded together using high impact energy generated by the explosion. Metals welded by this method are used for a various purposes.
