Ever wondered how to use a laser welding machine safely and effectively? This guide breaks down the essential steps, from preparation to shutdown, highlighting crucial safety precautions. Learn how to manage power supplies, water circulation, and gas connections, and understand emergency protocols. By the end, you’ll know how to operate a laser welding machine with confidence, ensuring both efficiency and safety in your welding projects.
A laser welding machine is a piece of equipment used for welding metals using a laser.
Based on its working mode, laser welding machines can be divided into various types, such as handheld laser welding equipment (also known as laser mold welding machines), automatic laser welding machines, jewelry laser welding machines, laser spot welding machines, optical fiber transmission laser welding machines, galvanometer welding machines, and handheld welding machines.
Apart from these commonly used types, there are also some specialized laser welding equipment available in the market. For instance, sensor welding machines, silicon steel sheet laser welding equipment, and keyboard laser welding equipment are some of the special types of laser welding machines.
Laser welding involves using high-energy laser pulses to heat a small area of a material. The laser’s energy is absorbed into the material, causing internal diffusion through heat transfer, resulting in the material melting and forming a specific molten pool.
This welding technique is relatively new and is primarily used for welding thin-walled materials and precision parts. Laser welding can be used for various welding types, including spot welding, butt welding, overlap welding, and seal welding.
It has the following advantages:
So, how should we use the laser welding machine safely and correctly?
Startup of laser welding machine:
Laser welding machine shutdown:
During operation, if an emergency occurs such as water leakage or abnormal sound of laser, press the emergency stop immediately and cut off the power supply quickly.
Before operating the laser welding machine, turn on the external circulating water switch of the laser welding machine.
It is strictly prohibited to start up the machine if the cooling system fails as the laser system adopts water cooling mode and the laser power supply adopts air cooling mode.
Do not disassemble any parts of the machine without proper authorization.
Do not weld when the safety door of the machine is open.
To avoid eye injury, it is forbidden to look directly at the laser or reflect the laser with your eyes when the laser is working. Instead, face the laser welding joint with your eyes.
In order to prevent fire and explosion, do not place inflammable and explosive materials on the laser light path or where the laser beam can be irradiated.
During operation, the circuit is in a state of high voltage and strong current. Therefore, it is strictly prohibited to touch any circuit components in the machine during operation.
Only trained personnel are allowed to operate this machine.
The laser welding machine has a high degree of automation and a simple welding process. The non-contact operation method meets the requirements of cleanliness and environmental protection.
Using the laser welding machine to process workpieces can significantly improve work efficiency. The finished workpieces have a beautiful appearance, small weld, large welding depth, and high welding quality.
The laser welding machine is widely used in dental denture processing, keyboard welding, silicon steel sheet welding, sensor welding, battery sealing cover welding, and other applications.
