Introduction to Precautions for Safe Use of Laser Welding Machines

Laser welding machines are generally used for butt welding and repair welding of metal materials. The working principle of laser welding is to use high-energy laser pulses to heat in a small area of the material. The high-temperature energy diffuses from the surface of the material to the inside, and a specific molten pool is formed after melting. The material is in a high-temperature state throughout the process, so how should we use the laser welding machine safely?

Precautions for safe use of laser welding machines

1. During operation, if there is an emergency, such as water leakage or abnormal laser sound, you need to press the emergency stop button immediately and quickly cut off the power supply.

2. The external circulation water switch of laser welding must be turned on before operation, because the laser system uses water cooling and the laser power supply uses air cooling. If the cooling system fails, it is strictly forbidden to start the machine.

3. It is strictly forbidden to touch all circuit components in the machine during operation. When the laser welding machine is working, the circuit is in a high voltage and strong current state. Untrained personnel are prohibited from operating the machine.

4. It is strictly forbidden to use eyes to scan the laser directly when the laser is working to avoid eye injury. It is forbidden to use external equipment to reflect the laser when the laser is working.

5. Do not disassemble any parts of the machine at will, do not weld when the machine safety door is open, and do not aim the laser head at the equipment parts.

6. Do not place flammable and explosive materials in the laser light path or where the laser beam can be irradiated to avoid fire and explosion.
