Laser welding with ALPHA LASER laser welding devices

Our laser welding systems yield high-strength precision seams

Whether joint welding or deposition welding, with wire or with powder: our goal is to make the laser welding process ever more precise, application-oriented, and faster. The good controllability of laser energy allows welding of metallic materials with high melting temperatures or high thermal conductivity. Materials that are otherwise difficult or impossible to fuse can often be jointed by laser welding.

Laser technology is indispensable when it comes to mechanically solid, precise, and visually appealing joints. Our laser welding systems use fiber lasers and Nd:YAG lasers for pinpoint energy input that results in less heat and thus prevents distortion of the material. Laser welding yields a smooth, oxide-free surface and a slim seam on butt welds, overlap welds, or fillet welds. Some of our laser systems can also be used for powder deposit welding. This process is perfectly suited to protect your components and tools as well as increase their service life, or for applying material even faster over larger areas.

  • Very small heat-affected zones
  • High mechanical strength of the welding seam
  • Contactless welding without force application onto the workpiece 
  • Good process control for consistent manufacturing quality
  • Good accessibility
  • Various materials can be welded
Advantages

 

Manual, semi-automatic, or fully automated laser welding

Our laser systems allow you to weld manually, semi-automatically, or automatically (with and without wire feed). Our handheld welding lasers give you maximum flexibility in laser welding. With manual laser welding, the filler material is fed manually and the welding process is monitored via the binocular. With semi-automated laser welding, the operator has the option of moving one or more axes automatically at a preset speed, so that he or she can use the joystick of the laser welding device to trace only curves or make minor corrections.

Automated laser welding systems use our WINLaserNC software, with which the welding process (paths and laser parameters) is programmed or taught-in. The filler material is fed to the laser welding machine by means of an automatic wire feed system. This approach is ideal for welding large areas or frequently recurring components. The process is controlled using the binocular or via our HDMI camera with monitor. The laser device also records video sequences with the HDMI recorder. Precision engineering companies and the automotive industry value our laser welding systems much like manufacturers dealing with laser sheet metal processing
