Projection Welding Uses. Conventional spot welding involves passing a high tension electric arc between two electrodes on either side of the material to be welded. This page introduces projection welding a method that adopts resistance welding principles.
Projection welds developed via the resistance welding RW process use the design or shape of the part to make discreet individual-point contacts to concentrate the current during welding. Projection welding is an ideal method of fastening attachments eg. Ad High Performance Wide Range Quality Structural Adhesives for Plastic Bonding.
Applications of Projection Welding.
Equipment used for projection welding is similar to that used for spot welding except that the rod electrodes are replaced by flat copper platens or dies as shown in Fig. What is a Projection Weld. Ii Small fasteners nuts etc. From 26 to 205 kA.
