SW-SW series laser welder is widely used in jewellery, dental and other fine workpieces. This kind machine can process all metals, such as gold, silver, platinum, titanium, stainless steel, brass and so on. It is mainly used for manufacturing and repairing jewelleries.

Jewellery Laser soldering

Lasers can weld all precious metals and their alloys without any  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.


Fine welding with Laser Spot Welder

The laser is an excellent tool for seam, butt and overlap welding of almost all common metals and their alloys. The wide range of tried and tested applications includes stainless steel, gold, silver, platinum and titanium, as well as shape memory alloys. Amongst these are some materials which are difficult, if not impossible, to join with conventional techniques. The Laser spot welder give extraordinary quality of laser welded joints from a machine that is quick and easy to use. Within a few minutes spot and seam welds can be realized with an accuracy in the micron range – even in complicated areas. The rule of thumb is: if you can see the joint, it can be laser welded. With a laser, experienced users can join filigree work-pieces with a fineness and precision which no other method can even remotely achieve

Perfect results by excellent performance

By matching the parameters and shape of the laser pulses to each material, the laser generates a minimal heat affected zone, thus meeting the precondition for welding temperature-sensitive components. Another positive effect of the low thermal load of the two parts is, that unwanted modifications of the joint by the welding process can almost always be avoided. 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.
