Laser welding
Laser welding is an effective method with many advantages. Imagine that you weld at a speed of 4 meters per minute, in 2 millimeters of stainless steel. You avoid problems with deformation and welding spray, and you get a smooth and high welding speed. The fact that you can also design parts for one-sided welding means that laser welding is well in competition with all other conventional welding methods. However, it should be kept in mind that laser welding usually requires higher demands on the detail, and positioning. Sometimes fixtures are required.
With the same equipment, you can easily use the laser for marking, serial number, text, or barcode in the same set-up as welding.
We are currently working with two suppliers, and one is running with manual lasers and the other has several robot cells and a high degree of automation. The same company can also laser cure.
Since laser welding is a very fast process, minimal heat occurs, which has many advantages.
- Straightening of the product after welding is not required since the changes of shape will be minimal.
- No grinding of welds, no welding spray residuals that needs to be removed, cosmetically good welds.
- You can combine different material types, such as copper (Cu) and aluminum (Al).
- You can also weld, for example, 0.1 mm sheet metal against a 1 mm plate.
- You can perform plastic welding with laser, provided that the plastics are compatible with each other.
- The welding method is one-sided and non-contact, which also has its advantages especially when it comes to design.
