The correct usage process of laser welding machine is as follows:
Operating environment: laser welding machine.
1. Check whether the power supply and water circulation of the laser welding machine are normal; check whether the gas connection of the equipment in the machine is normal; check whether there is dust, spots, oil stains, etc. on the surface of the machine.
2. Turn on the laser welding machine: connect the power supply and turn on the main power switch; turn on the water cooler, laser generator, etc. in sequence; open the air valve to adjust the air flow; enter the current working parameters to be executed; Perform welding operations.
3. Shut down the laser welding machine: Exit the program and turn off the laser generator; turn off the dust collector, water cooler and other equipment in order; close the gas cylinder valve; turn off the main power switch.
Using laser welding machining can effectively improve work efficiency. After welding, the finished workpiece has beautiful appearance, small welding seam, large welding depth and high welding quality. Laser welding machines are widely used in various fields. When using them, remember to use the correct process to prevent problems before they occur.
Precautions for use:
1. When using a laser welding machine, use a microscope to observe the workpiece and welding conditions, observe with both eyes at the same time, or use CCD to track the weld bead. Observe the welding condition of the workpiece.
2. During operation, consider whether to add welding wire according to the condition of the workpiece.
3. Different workpiece materials have different welding requirements and welding parameters.
4. The laser welding machine must be protected by argon gas to prevent oxidation of the welded workpiece, and the welded workpiece is relatively beautiful.
5. When laser welding, the most common thing is that there are bite marks around the welding part. Use laser air drilling to cover the welding part after air drilling to prevent the appearance of bite marks. The light spot can exceed the welding position (0.1mm).
