Research & Development : Advanced Joining Technologies

Several advanced joining technologies are being developed at Cosma. Some of the joining techniques that have been implemented include remote laser welding, resistance braze spot welding (RBSW), single sided spot welding (SSW), and tandem mig welding. Remote laser welding systems deliver speed and weld access advantages by way of rapid laser beam movement from one weld location to the next.

RBSW provides a high speed and low heat method of joining closed sections. The result of this unique process is a dimensionally and structurally superior assembly. SSW allows for the joining of sheetmetal stampings to tubular sections without the need for weld access holes in the tubes. Tandem mig welding is a process that dramatically increases the speed of the weld, thus reducing assembly cost, and it is easily adaptable to existing equipment.
