The emergence of laser technology has accelerated the development of human society, especially in the field of industrial manufacturing. Laser technology has greatly improved the working efficiency of product processing, improved the quality of industrial products, shortened the production cycle of products, and provided a strong guarantee for the batch automatic production of products. At present, the welding processing technology of laser welding machine is widely used in the field of industrial manufacturing, such as automobile electronics and battery manufacturing, machinery manufacturing, construction, steel welding. Laser welding plays an important role in the field of industrial manufacturing. Its working principle is to use the laser beam with high energy density as the heat source to carry out an efficient and precise welding process for welding materials.
So what safety regulations should be paid attention to when using laser welding machine for welding processing?
1. Before using the equipment, it is necessary to conduct a comprehensive inspection to check whether the power supply of the laser welding equipment is powered on; Whether the water circulation system can work normally. Check the internal standby gas connection of the equipment; Check the equipment workbench for dust, spots and oil stains. If necessary, clean it to ensure that the equipment can operate normally.
2. Start up the laser welding equipment for inspection, turn on the main power switch to power on the equipment, and then turn on the water circulation system, laser generator, etc; Then open the argon valve and adjust the gas flow to the appropriate state; Enter the current working parameters to be executed; Try welding.
3. In the shutdown process of laser welding equipment, first turn off the program, and then turn off the laser generator; Then turn off the dust remover and water circulation system equipment; Close the valve of argon cylinder; Finally, turn off the main power switch.
4. In case of water leakage, abnormal sound from the laser and other emergencies during welding operation, press the emergency stop button quickly and turn off the power immediately; Turn on the external circulating water switch of the laser welding equipment before equipment operation. Since the laser welding power supply is cooled by natural air and the laser system is cooled by water circulation, it is strictly prohibited to start the machine when the cooling system fails.
5. The internal parts of the laser welding machine are responsible for some functions and shall not be disassembled or replaced at will. The safety door of the equipment shall be closed during the welding process. When the laser is working, it is strictly forbidden to look directly at the laser or face the laser welding joint directly, because the laser brightness is very high, which will cause eye burns and permanent injury; It is strictly prohibited to stack flammable and explosive materials on the laser workbench or where the laser beam can be irradiated, so as to avoid fire and explosion accidents.
When the laser equipment is in high voltage state, it is strictly forbidden to touch the electronic components inside the equipment by hand. The operation of the laser welding machine for welding processing requires training before taking the post. It is not allowed to operate the machine without training.
