CEP's contact tips are manufactured from a double-walled composite tube, with a shell consisting of highly conductive pure copper and a core of copper-based high-temperature material. The latter is more resistant to the high-temperature wear that contact tips are exposed to. CEP has now developed a new core material that is even more wear-resistant. It's called Wolfram-Discup (engl. Tungsten) and is particularly suitable for long welding operations where, for quality control reasons, any interruption due to the changing of contact tips is ruled out.
Such operations include long seams on large installations. Continuous welding is also often required for vehicle bodies, ships' hulls, and aircraft fuselages – and especially where safety is a priority. These operations can take an long time: a specific case involved the production of turbine blades using WAAM, a wire-based additive manufacturing process. The new high-performance contact tips from CEP Freiberg achieved the required service life of 82 hours.
