Coldweld™

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 cold welding 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.
