Introduction
The cold welder is a tool to joint non-ferrous metals and their alloys without using heat, fillers or fluxes. Round wire sections, dissimilar materials and materials of different sizes can all be welded. The wires after welded remains the performance, the tensile strength even become stronger and the resistivity will not become larger than the original wires. So this cold welding has advantages compared to other ways.
Copper wires and its alloys can be welded is from φ0.*5 to *3mm,
Aluminum wires and its alloys can be welded are from φ 0.*7  to*5mm.
