Coldweld ™

Coldweld ™ Technology

Cold welding is a method for joining 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 with proven BWE Coldweld technology. A cold weld is generally stronger than the parent material and has the same electrical characteristics.

In order to obtain a true weld, all contaminants (oxides, oils, chemicals etc) must be removed so that clean surfaces can be brought together. BWE cold welding machines achieve this by using a multiple upset technique which ejects the contaminated material from the weld zone eliminating the need for any special preparation.

A wide range of cold pressure welding machines are available covering applications from rod to fine wire. BWE offer a facility for test welding customers material to confirm its suitability for cold welding.
