| Jewelry Laser soldering |
|
|
| Lasers 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 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. 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, |
| or can be ignored completely. |
