Projection Welding
 Miyachi Europe offers a variety of proven resistance welding methods. Projection welding differs from spot welding in that one or more projections are attached to one of the two workpieces that are to be joined. The projection forms a defined current conduction point. The parts are placed on top of each other and welded together at this point with large-area electrodes by a current pulse under the infuence of the electrode force. Several projections can also be welded at the same time.

Projection Welding Applications

Projection Welding Benefits:
-
The welding current is concentrated on the joint by a projection or profile on one of the individual parts.
-
Flat electrodes can be used with a large contact surface area whose shapes match the area of the workpiece.
-
The use of flat electrodes means longer shelf-life, virtually no deformation or discoloration on the workpiece and perfect fit in high-volume production applications.
-
This resistance welding method is also designed to allow for multi-projection welding whereby a corresponding number of electrodes or a pair of large-surface electrodes is fed from a single power source.
