Weld Systems Integrators Inc. (WSI) launched its 12-kJ capacitive discharge (CD) welder series. These welders are for projection welding fasteners, with standard or ring type projections, to hot-stamped aluminum silicate-coated materials, galvanized and other coated materials. The integrated welder design includes a fast follow-up head and an active displacement system for graphing displacement (specific distance of the weld projections collapse vs. weld time) for every weld. An inline force transducer measuring actual weld force in real time is also installed. The welder has a minimum 18-in. throat depth.
