Case Overview

CINA Laser repaired a GW 2kW industrial fiber laser with a burned QBH connector, restoring stable output and consistent performance for industrial use.

Before Repair

  • Laser Brand:GW
  • Rated Power:2kW
  • Application:Industrial laser processing
  • Condition:
    QBH connector burned before shipment
    Unstable output
    Reduced performance
    Unable to maintain normal operation

Repair Process

  • System Inspection:Complete startup check and optical path diagnostics.
  • QBH Replacement & Fiber Splicing:High-precision splicing to restore optimal beam quality.
  • Optical Path Organization:Secure fiber routing to prevent stress or misalignment.
  • Output Power Verification:Measure and verify laser output stability.
  • Final System Validation:Confirm full operational readiness.

After Repair

  • QBH replaced and optical path fully aligned
  • High-precision fiber splicing completed
  • Stable output power and optimized beam quality
  • Laser system fully restored to operational specifications
  • Extended service life without full replacement
