Scope of application of cold welder: Used for cold pressure welding of copper wire, aluminum wire and nonferrous metals such as gold, silver, nickel, platinum, zinc, tin, tantalum and niobium and some alloy wires.
The welding principle of cold welding tongs: Cold pressure welding is a method of welding copper and aluminum wires and alloys by applying pressure without using electricity, heat, fillers and flux during welding. Under the action of concentrated pressure load, the surface area of the two contact surfaces that need to be connected is expanded. The expansion of the area causes the original protective film on the surface to hinder the welding to break. The bonding between atoms can continue to be welded by continuing to apply force.
