What is the benefit of spot projection welding?
- 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.
