Principles
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 BWE's proven 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's 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 welding machines is available covering applications from rod to fine wire. BWE's Autoweld system offers powered machines that are economic and easy to use. BWE's cold weld machine dies are manufactured using the latest computer controlled equipment and hand finished to ensure the highest possible standards.

Cold welding machines and dies have been supplied world-wide to the wire & cable industry from our Ashford factory since 1969. BWE has supplied over 10,000 cold welding machines to satisfied customers throughout the world.

BWE offers a facility for test welding customers' material to confirm its suitability for cold welding.

In April 1996 BWE introduced the Autoweld system which has no hydraulics, no pneumatics and no electronics - not surprisingly it is very competitively priced. The Autoweld principle (patent applied for) is based on a simple a.c. motor and gearbox utilising a special cam to generate die movement and match mechanical advantage to the cold weld load characteristics.
