ABOUT Cold Welding

WHAT IS A COLD WELDING?

Cold welding, also known as cold pressure welding or contact welding, is a welding process that joins two clean metal surfaces together by using enough pressure to create metallurgical bonds.

Process of Cold Welding:

The applied pressure brings the surfaces of the work pieces together. The Nano scale distance becomes irrelevant, and metal atoms jump from one piece to another. This results in a near-perfect bond with almost no repercussions, and the two separate pieces of metal become a similar mass.

But to achieve this, you need to clean the metal surfaces to perfection. Every metal has oxide layers that must be removed before attempting to cold weld.

Scope of Cold Welding:

Cold welding is used by numerous industries, including aerospace, automotive, iron steel, electronics, and production.
