Laser welding machine is generally used for welding and repair welding of metal materials. The working principle of laser welding is to use high-energy laser pulse to heat in the small area of the material. The high-temperature energy diffuses from the surface of the material to the inside, and forms a specific molten pool after melting. The materials in the whole process are in high temperature, so how can we safely use the laser welding machine?
Precautions for safe use of laser welding machine
1. During operation, in case of emergency, such as water leakage or abnormal sound of the laser, it is necessary to immediately press the emergency stop button and quickly cut off the power supply.
2. The external circulating water switch of laser welding must be turned on before operation, because the laser system adopts water cooling mode and the laser power supply adopts air cooling mode. If the cooling system fails, it is strictly prohibited to start the machine.
3. It is strictly prohibited to touch all circuit components in the machine during operation. When the laser welding machine is working, the circuit is in the state of high voltage and strong current. Untrained personnel are prohibited to operate the machine.
4. It is forbidden to scan the laser directly with eyes when the laser is working to avoid eye injury. It is forbidden to use external equipment to reflect the laser during laser operation.
5. Do not disassemble any parts of the machine at will, do not weld when the safety door of the machine is opened, and do not aim the laser head at the equipment parts.
6. Do not place flammable and explosive materials in the place where the laser light path or laser beam can reach, so as to avoid fire and explosion.
