Laser spot welder can weld all precious metals and their alloys without any filler or soldering material. Robust, invisible repairs of high quality can be achieved within a short time: cleaning porous surfaces of platinum and gold cast parts, repair of claws, or processing of ring sizes. The laser optimizes the production process and opens up possibilities for completely new designs. The comparatively narrow processing window for highly reflective materials such as silver and gold, requires a perfect and consistent beam quality in order to keep the weld quality constant.
Laser welded joints are of high strength and resist even high mechanical strain without any wear. Other than adhesive seals, they are temperature-resistant and show pore-free surfaces. Compared to other joining techniques, post processing of laser weld is reduced to only a few simple steps,or can be ignored completely.
