Three-Axis YAG Current Feedback Laser Welding Machine

Three-Axis Fiber Transmission Laser Welding Machine

The CNC laser welding system is widely used in the industrial precision welding of optical communication devices, IT, medical treatment, electronics, batteries, fiber couplers, picture tube electron guns, metal parts, mobile phone vibration motors, precision parts of clocks and watches, car lights and so on.

Fiber Transmission Current Feedback Laser Welding Machine for Precision Welding

The 3-Axis YAG fiber transmission laser welding machine adopt fiber laser device as the laser generator, whole machine free of maintenance, no consumables, strong welding effect and more fine weld seam. With good beam quality, good laser spot, strong penetration and fiber transmission, an excellent non-contact, long-distance, precision spot welder is produced.

The current feedback technology can make the laser output energy has a good repeatability, in simple words, is to ensure that the output of laser energy is stable, which can effectively reduce the failure rate of products. The fiber laser in the current feedback fiber transmission laser welding machine, after the optical fiber output collimation and focusing, can weld the welding parts in multiple or multi-points, which has the advantages of good beam quality, even and small spot, convenient installation and movement, etc.

This automatic laser welding machines can meet the needs of users in different industries according to the matching shape and workbench on the production site and the automation work,widely used for seam welding,stainless steel,alloy ,brass,galvanized sheet high precision welding. It can weld a wide range of metal incuding the sainless steel, carbon steel, aluminum, galvanied plate etc.

Features:

  • High aspect ratio, thin line weld width, minimal heat-affected zone, zero deformation, and fast welding speed
  • Smooth and clean weld with or without simple process after welding
  • High weld strength, no porosity, eliminates the impurities of the base metal
  • The microstructure can be refined after welding, weld strength is at least equal to or exceeds base metal strength
  • Tiny laser spot can be precisely positioned and easily automated
  • Suitable dissimilar metal welding
  • Excellent for spot welding, butt welding, overlap sealing welding

Welding Head:

1. This welding head is suitable for 500W and below power band.
2. Special optimization and upgrading for specific use environment to achieve reliable and stable operation for a long time in daily industrial manufacturing.
3. With excellent welding quality and speed, it realizes seamless connection and deep integration with the system to further improve the production and processing efficiency.
4. The internal structure of the laser head is completely sealed to avoid contamination of the optical lens.
