Manhart How to use handheld laser welding machine correctly

The correct use of handheld laser welding machines involves a series of steps and precautions to ensure welding quality, operational safety, and stable equipment operation. The following is a detailed usage method:
###1、 Preparation before operation
1. * * Check the equipment * *:
-Ensure that the handheld laser welding machine is intact and undamaged, and that the power cord, laser head, and other components are securely connected without any looseness.
-Check if the water circulation system is functioning properly to ensure good cooling of the laser generator.
-Check if the gas connection of the equipment inside the machine is normal and ensure smooth airflow.
-Clean the surface of the machine to ensure that there is no dust, flower spots, oil stains, etc., so as not to affect the welding effect.
2. * * Security Protection * *:
-Wear protective goggles, gloves, and other safety equipment to avoid laser damage to the eyes and skin.
-Ensure that the work area is clean and free of flammable and explosive materials to prevent fires or explosions.
3. * * Set welding parameters * *:
-Set appropriate welding parameters based on the type, thickness, and welding requirements of the welding material, such as laser power, welding speed, wire feeding speed, focal position, etc.
4. Fixed workpiece:
-Fix the workpiece to be welded in the appropriate position to ensure that there is no displacement during the welding process.
###2、 Operation steps
1. * * Power on preheating * *:
-Connect the power and turn on the main power switch.
-Turn on the water cooler, laser generator, and other equipment in order for preheating. The preheating time is usually 5-10 minutes to ensure stable operation of the equipment.
2. * * Adjust the laser head * *:
-Adjust the position and focal length of the laser head according to the welding requirements and workpiece thickness, ensuring that the laser beam is perpendicular to the surface of the welding material.
3. * * Start welding * *:
-Place the welding wire (if needed) into the wire feeding mechanism, adjust the wire feeding speed to synchronize the movement of the welding wire with the laser beam.
-Press the welding switch to start welding. During the welding process, it is necessary to maintain a stable welding speed and wire feeding speed to ensure the quality of the weld seam.
4. * * Monitor welding quality * *:
-Real time observation of welding quality, and timely adjustment of welding parameters if necessary.
5. * * Complete welding * *:
-When the welding requirements are met, release the welding switch and turn off the wire feeding mechanism (if any).
-After waiting for the equipment to cool down, turn off devices such as water coolers and laser generators.
###3、 Precautions
1. Safety comes first:
-Strictly adhere to safety operating procedures to ensure personal and equipment safety.
-Avoid direct irradiation of the laser beam onto the human body or other flammable materials.
2. * * Reasonable selection of parameters * *:
-Reasonably select welding process parameters based on the thickness, material, and welding requirements of the material to ensure the quality of the weld seam and stable operation of the equipment.
3. * * Regular maintenance * *:
-Regularly maintain the handheld laser welding machine, clean the surface and internal dust of the equipment, and check whether each component is loose or damaged.
4. * * Urgent handling * *:
-During the operation, if there is an emergency situation (such as water leakage, abnormal sound from the laser, etc.), immediately press the emergency stop button and quickly cut off the power.
5. * * Prohibited Behavior * *:
-Do not disassemble any components inside the machine at will.
-Welding is not allowed when the machine safety door is open.
-It is strictly prohibited to directly look at the laser or reflect the laser with the eyes while the laser is working.
In summary, the correct use of handheld laser welding machines requires following a series of steps and precautions to ensure welding quality, operational safety, and stable equipment operation.
