Main system components of automatic laser welding:
The main components of the automatic laser compression welding system are: laser compression welding gun (servo system, unidirectional or C-type welding clamp), laser compression welding control system, laser compression welding gun cleaner, water chiller, welding robot, and fence (no laser room required)
Laser Safety Standards
1. According to authoritative SGS testing, it complies with IEC 60825-1:2014 standards, and the protective casing passed laser leakage inspection.
2. It meets Class 1 laser safety level, with an actual measured laser power of 0.010mW, far below the 0.39mW standard limit.
3. Multi-area 5-point on-site measurements show that the laser protection performance is significantly better than SGS testing standard requirements.
4. Uses a calibrated laser power meter for testing, ensuring the data is true and effective, with laser safety protection reaching industry high standards.
Laser spot welding without laser room design:
1. Alternative laser room design | Space-saving, easy to install, high protection, laser safety compliance in one step
2. No need to build a laser room, integrated protective housing, SGS certified Class 1 laser safety level, more efficient industrial production
Advantages compared to traditional laser welding
