Handheld laser welders offer precision, speed, and flexibility for various welding applications. However, regular maintenance and proper troubleshooting are essential to ensure consistent performance and avoid common welding issues. This guide explores routine maintenance tasks and provides clear solutions to frequent welding challenges.

Regular Maintenance: Keeping Your Laser Welder in Optimal Condition

Performing regular maintenance is critical to preserving the functionality and lifespan of your handheld laser welder:

Every 8 hours:

• Inside the Welding Machine: Use clean, dry gas to blow out dust and remove oil stains.

• Condenser: Inspect for accumulated dust or foreign objects and clean lightly using compressed air.

• Sheet Metal Exterior: Wipe down surfaces to remove dust, dirt, and grease.

• Dustproof Filter: Detach and blow clean using dry gas.

• QBH Connector: Ensure the connector is securely tightened and not loose.

Every 40 hours:

• Gas Circuit Components and Pipelines: Inspect thoroughly to ensure gas flow remains unobstructed.

Addressing Common Welding Issues

Even with routine maintenance, certain issues may arise during welding. Here's how to identify, analyze, and fix these problems effectively:

1. Black Weld Seam

Cause: The metal oxidizes when heated in air, forming black oxide. Inert protective gas prevents oxygen from contacting the weld surface.

Solution: Adjust protective gas flow appropriately, and ensure there is an adequate gas supply.

2. Weld Excessive Penetration

Cause: Inappropriate welding power and speed cause partial melting of the base material. When surface tension can't support heavy liquid metal, the weld center sinks, resulting in collapse.

Solution: Increase the wire feeding speed and reduce welding power setting

3. Weld Burrs and Spatter

Cause: High laser power density quickly heats metal to its boiling point, causing liquid metal to eject from the molten pool due to internal pressure changes.

Solution: Adjust laser power to a moderate level and reduce protective gas flow.

4. Weld Perforation

Cause: The splicing gap is too large, preventing the weld from being properly filled.

Solution: Reduce the splicing gap to ensure effective weld filling.

 5. Irregular Welds (Discontinuous or Raised)

Cause: Incorrect welding wire specifications, material mismatch, or uneven wire feeding.

Solution: Choose the correct welding wire specification and material, and ensure uniform wire feeding speed during welding.

 6. Wire Not Melting Properly, Resulting in Weak Welds

Cause: Excessive wire feeding speed, inadequate welding power, or misalignment between welding wire and laser center.

Solution: Reduce the wire feeding speed, increase laser power, and correctly align the welding wire with the laser.

7. Welding Process Interruption

Cause: Poor or inconsistent wire feeding.

Solution: Ensure the wire feeder and connecting pipe match wire specifications, straighten the wire feeding tube, and minimize bending or coiling of wire.
