What are the precautions for using laser welding machines

The workpiece of the laser welding machine melts and even vaporizes rapidly after absorbing the laser. The molten metal forms a small hole under the action of steam pressure. tension and gravity balance. So what do we need to pay attention to when using it?

Precautions for using laser welding machine

1. Equipped with responsible personnel with relevant knowledge and experience of laser and welding machines. The responsible personnel should not only master the safety lock key and password of the welding machine, but also instruct the operator how to use the welding machine.

2. Establish a dedicated laser welding area, and set up relevant signs such as "Idlers are prohibited from approaching" in the welding area.

3. Install the welding machine in a level and firm place, not in an inclined place.

4. . Please use this welding machine in an environment where the ambient temperature is 5°C~3 0°C and the humidity is not greater than 35%. The ambient temperature should not fluctuate too much. It is forbidden to use this welding machine in the following environments: environment with oil pollution; environment with vibration; environment with corrosion; environment with high frequency noise; environment with humidity; environment with high concentration of carbon, nitrogen and sulfur oxides.

5. In winter, if the ambient temperature drops below 0°C, the water in the water tank will freeze, and the water tank may freeze and burst. So take special care to ensure that the ambient temperature of the welding machine does not drop below 0°C in winter. If the ambient temperature drops below 0°C, please drain the water in the water tank first, and refer to the introduction in relevant chapters.

6. If the ambient temperature changes drastically, water vapor will form on the YAG laser rod and lens, which will affect the use of the welding machine. Therefore, prevent drastic changes in the environment as much as possible. If water vapor has been formed, warm up for a while after turning on the machine before using the machine.

7. If the casing of the welding machine has stains or water, please wipe it with a dry or damp cloth. If the stain cannot be wiped clean, it can be wiped clean with neutral detergent or alcohol. Do not wipe the machine with gasoline or paint thinner.

8. It is forbidden to put screws or coins inside or outside the welding machine, which may cause a short circuit and damage the machine.

9. Please operate the button gently by hand, and do not touch the button with a screwdriver or other tools. In particular, do not touch the touch screen with sharp objects, as this will cause permanent damage to the touch screen. The touch screen should be operated with fingers or a dedicated stylus.

10. Do not operate buttons and switches continuously, and ensure that they are only pressed once each time. Repeated switching has an impact on the life of the machine.

11. The control box and the welding machine are connected by connecting wires. After dismantling, make sure all the connecting wires have been restored before the next use. At the same time, do not let the connecting wire face the optical fiber.

12. Ineffective laser shield interlock switch is strictly prohibited.

13. A workbench that complies with EU safety directives must be installed to start the machine.

14. When connecting the optical fiber for maintenance and debugging, turn the main switch to the off position and lock it. The key must be kept by a special person.

The above is the introduction to the precautions for the use of laser welding machines. This welding mode has a large penetration depth and a large aspect ratio. When the small hole moves along the welding direction with the laser beam, the molten metal in front of the small hole of the laser welding machine bypasses the small hole and flows to the rear, and forms a weld after solidification. Only after mastering the matters needing attention can a win-win situation be achieved
