Laser welding machine, also known as laser welding machine, laser welding machine, is a laser material processing machine. According to its working mode, it can be divided into laser mold welding machine (manual laser welding equipment), automatic laser welding machine, jewelry laser welding machine, laser spot welding machine, optical fiber transmission laser welding machine, vibrating mirror welding machine, handheld welding machine, etc. Special laser welding equipment has sensor welding machine, silicon steel laser welding equipment, keyboard laser welding equipment.
Laser welding uses high-energy laser pulses to heat materials locally in a small area. The energy of laser radiation diffuses to the interior of the materials through thermal conduction, and the materials are melted to form a specific molten pool. Laser welding is a new type of welding, mainly for thin-wall materials, precision parts welding, spot welding, butt welding, overlap welding, sealing welding, high depth to width ratio, welding width is small, heat affected zone is small, small deformation, welding speed, smooth weld, beautiful, no processing or simple processing after welding, welding quality is high, no porosity, can be precise control, Small focus spot, high positioning accuracy, easy to realize automation.
Safe and correct use of laser welding machine precautions analysis:
1. Preparation before starting the laser welding machine
Check the laser welding machine power supply, water circulation is normal; Check whether the gas connection of the equipment in the machine is normal; Check that the surface of the machine is free of dust, speckle, oil, etc.
2, laser welding machine on/off
Laser welding machine boot: power on, open the main power switch; Turn on the water cooler, laser generator, etc.; Open the argon valve and adjust the gas flow; Enter the current work parameters to be executed; Perform welding operations.
Laser welding machine: exit the program, close the laser generator; Shut down the dust removal machine, water cooler and other equipment in sequence; Close the argon cylinder valve; Turn off the main power switch.
3, laser welding machine safety precautions
In the process of operation, if there is an emergency (water leakage, abnormal sound of laser, etc.), press the emergency stop immediately and quickly cut off the power supply; The outer 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 wind cooling mode, if the cooling system is faulty, it is strictly prohibited to turn on the machine.
Do not disassemble any parts in the machine at will, do not weld when the machine safety door is opened, do not look at the laser with your eyes or reflect the laser, and use your eyes to weld the laser head, so as to avoid eye injury; 5. Flammable and explosive materials shall not be placed on the laser optical path or where the laser beam can be irradiated, so as not to cause fire and explosion.
When the laser welding machine is working, the circuit is in the state of high voltage and strong current. It is strictly prohibited to touch the circuit components in the machine while working. It is forbidden to operate the machine without training.
Laser welding machine high degree of automation welding process is simple. The non-contact operation method can meet the requirements of clean and environmental protection. Using laser welding machine to process the workpiece can improve the work efficiency, the finished workpiece appearance is beautiful, the weld is small, the welding depth is large, the welding quality is high. Laser welding machine is widely used in dental denture processing, keyboard welding, silicon steel sheet welding, sensor welding, battery sealing cover welding and so on.
