How to Use Laser Welding Machine Safely and Correctly?

Laser welding machine is a equipment for metals welding by laser.

Laser Welding Machine

According to its working mode, it can be divided into laser mold welding machine (handheld laser welding equipment), automatic laser welding machine, jewelry laser welding machine, laser spot welding machine, optical fiber transmission laser welding machine, galvanometer welding machine, handheld welding machine, etc.

Special laser welding equipment includes sensor welding machine, silicon steel sheet laser welding equipment and keyboard laser welding equipment.

laser welding

Laser welding is the use of high-energy laser pulses to locally heat the material in a small area. The energy of laser radiation is directed to the internal diffusion of the material through heat transfer, and the material is melted to form a specific molten pool.

Laser welding is a new type of welding method, which mainly aims at the welding of thin-walled materials and precision parts.

Laser welding is the use of high-energy laser pulses to locally heat materials in small areas.

The energy radiated by laser is diffused inside the material through heat transfer, and the material is melted to form a specific molten pool.

Laser welding is a new welding method, which mainly aims at the welding of thin-walled materials and precision parts.

It can realize spot welding, butt welding, overlap welding, seal welding, etc.

It has the following advantages:

  • Depth width ratio;
  • Small weld width;
  • Small heat affected zone and deformation;
  • Fast welding speed;
  • The weld is flat and beautiful;
  • No treatment or simple treatment after welding;
  • High weld quality; No pores;
  • Precise control;
  • Small focus spot;
  • High positioning accuracy;
  • Easy automation.

So, how should we use the laser welding machine safely and correctly?

correct use of laser welding machine

Analysis of precautions for safe and correct use of laser welding machine:

1. Preparation before starting the laser welding machine

  • Check whether the power supply and water circulation of the laser welding machine are normal;
  • Check whether the gas connection of equipment in the machine is normal;
  • Check that the machine surface is free of dust, spots, oil stains, etc.

2. Laser welding machine on / off

Startup of laser welding machine:

  • Turn on the power supply and turn on the main power switch;
  • Turn on the water cooler and laser generator in sequence;
  • Open the argon valve and adjust the gas flow;
  • Enter the working parameters to be executed currently;
  • Perform welding operations.

Laser welding machine shutdown:

  • Exit the program and turn off the laser generator;
  • Turn off the dust remover, water cooler and other equipment in sequence;
  • Close the valve of argon cylinder;
  • Turn off the main power switch.

3. Precautions for safe use of laser welding machine

During operation, in case of emergency (water leakage, abnormal sound of laser, etc.), press the emergency stop immediately and quickly cut off the power supply;

The external circulating water switch of laser welding must be turned on before operation.

Since the laser system adopts water cooling mode and the laser power supply adopts air cooling mode, it is strictly prohibited to start up if the cooling system fails.

Do not disassemble any parts in the machine at will;

Do not weld when the safety door of the machine is open;

It is forbidden to look directly at the laser or reflect the laser with your eyes when the laser is working, and face the laser welding joint with your eyes to avoid eye injury;

Inflammable and explosive materials shall not be placed on the laser light path or where the laser beam can be irradiated, so as to avoid fire and explosion.

When the laser welding machine works, the circuit is in the state of high voltage and strong current.

It is forbidden to touch all circuit components in the machine during operation;

Untrained personnel are not allowed to operate this machine.

The laser welding machine has a high degree of automation and simple welding process.

The non-contact operation method can meet the requirements of cleanliness and environmental protection.

Using laser welding machine to process workpieces can improve work efficiency.

The finished workpieces have beautiful appearance, small weld, large welding depth and high welding quality.

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.
