With the continuous development of science and technology, laser technology has developed steadily in various industries, but laser welding machines have appeared in our lives, such as stainless steel, aluminum (home, cabinets, kitchens, stair elevators, shelves, ovens) , doors, windows, guardrails, distribution boxes), etc. However, in the process of using laser welding equipment, there will be more or less failures. Of course, any machine has the possibility of failure. In order to make the laser welding machine more To do a good job, reduce the number of failures and increase work efficiency, we must understand the working principle of the laser welding machine.

Let Suntop laser explain to you the common faults and treatment methods of laser welding machines

Fault 1. The weld seam is very black when the laser welding machine is welding

1. The nitrogen is not turned on, just turn on the nitrogen to solve it. the

2. The airflow direction of the shielding gas is wrong, and the airflow direction of the shielding gas should be opposite to the movement direction of the workpiece. 


Fault 2. Cracks appear when the laser welding machine is welding

1. The cooling speed of the workpiece is too fast, the temperature of the cooling water on the fixture should be adjusted to increase the water temperature. the

2. If the fit gap between the workpieces is too large or there are burrs, the machining accuracy of the workpieces should be improved. the

3. The workpiece has not been cleaned. In this case, the workpiece needs to be cleaned again. the

4. The flow rate of the shielding gas is too large, which can be solved by reducing the flow rate of the shielding gas.


Fault 3. The penetration depth of laser welding machine welding is not enough

1. The laser energy is not enough, you can increase the pulse width and current to solve it. the

2. The defocus amount of the focusing mirror is wrong, and the defocus amount should be adjusted to a position close to the focus.


Fault 4. The flame weakens when the laser welding machine is welding

1. The optical shutter is not fully opened, check and add lubricating oil to the optical shutter connection to make the connection smooth mechanically.

2. The laser offset of the main optical path, adjust the total reflection and semi-reflective film of the main optical path, check and adjust the light spot with a photo paper. the

3. If the cooling water is polluted or the cooling water has not been replaced for a long time, it can be solved by replacing the cooling water and cleaning the UV filter glass tube and xenon lamp. the

4. The laser does not output from the center of the copper gas nozzle under the focusing head, adjust the 45-degree reflective diaphragm to make the laser output from the center of the gas nozzle. the

5. If the focusing lens or the resonant cavity diaphragm of the laser is damaged or polluted, it should be replaced or cleaned in time.

When the laser welding machine breaks down, we can refer to the above content to check the operation. If there are any problems that cannot be solved, please consult Suntop laser technicians online.
