Manhart How to improve the performance stability of handheld laser welding machines?

To improve the performance stability of handheld laser welding machines, the following key aspects can be followed:
1、 Optimize welding parameters
1. * * Laser power, speed, and spot size * *:
-Determine the appropriate laser power, speed, and spot size based on the specific material, thickness, and required weld quality of the workpiece. Appropriate parameters can ensure the stability of weld quality.
-For thick plates or high carbon equivalent materials, it is necessary to increase laser power appropriately to ensure good fusion; For thin plates or high thermal conductivity materials, it is necessary to reduce the welding speed to prevent joint deformation caused by excessive heat input.
2、 Improve the stability of welding equipment
1. * * Normal operation of equipment * *:
-Regularly inspect and maintain the laser welding machine to ensure it is in optimal working condition.
-Inspect and maintain the cooling system, power supply system, gas system, etc. to ensure stable and reliable operation of the equipment.
2. Stability of equipment and workpiece:
-During the welding process, ensure that the equipment and workpiece remain stable and avoid shaking, vibration, etc. of the machine and workpiece.
-Measures such as clamping fixtures and reducing machining errors can be used to ensure the stability of the machine and workpiece.
3、 Improving sheet metal surface treatment
1. * * Remove rust and oil stains * *:
-Before welding, necessary cleaning treatment should be carried out on the workpiece to thoroughly remove dirt such as oil and rust, in order to reduce the introduction of impurities during the welding process.
2. * * Uniform surface treatment * *:
-Pay attention to the uniform treatment of the workpiece surface to reduce the occurrence of cracks and other phenomena in the weld seam, and ensure the stability of welding quality.
4、 Using high-quality protective gas
1. * * Gas type and flow rate * *:
-Select high-purity and stable flow shielding gas to ensure the quality and stability of the weld seam.
-For strict requirements, a protective gas with a small amount of active elements added can be used to improve the fluidity of the molten pool.
5、 Improving the quality of base materials
1. * * Select high-quality base material * *:
-Select base materials with chemical composition and mechanical properties that meet the requirements to ensure the stability of welding quality.
-For materials with high carbon equivalent or high alloying element content, appropriate pretreatment should be carried out to improve weldability.
6、 Regular maintenance and upkeep
1. * * Clean the body * *:
-Regularly clean the body, keep its appearance clean, and reduce the accumulation of dust and impurities.
2. * * Replace filter and cooling water * *:
-Regularly replace filters and cooling water to maintain the normal working condition of the equipment.
-Check the conductivity of the internal circulating water once a week and replace the deionized water of the internal circulating water once a month.
3. * * Check the optical system * *:
-Regularly clean the optical path system and keep it clean to ensure the efficiency of laser transmission.
4. * * Control system inspection * *:
-Regularly check the working status of the control system to avoid malfunctions.
By implementing the above measures, the performance stability of handheld laser welding machines can be significantly improved, ensuring the reliability and consistency of welding quality. At the same time, it can also extend the service life of the equipment and reduce maintenance costs.
