MAX High Power Fiber Laser repair

MAX Photonics MFPT-M+ series is a high-power multimode fiber laser designed for industrial cutting/welding. Its technical highlights include:

Power coverage: 1000W~6000W (suitable for carbon steel/stainless steel medium and thick plate processing)

Energy efficiency ratio: electro-optical conversion efficiency ≥35% (50% energy saving compared to CO₂ laser)

Stability: ±2% power fluctuation (24-hour continuous operation)

Intelligent interface: supports MODBUS/CAN bus remote monitoring

Typical applications: sheet metal cutting, new energy battery welding, heavy machinery manufacturing

II. Common fault diagnosis and precise maintenance solutions

1. Laser power attenuation (top 1 high-frequency fault)

Root cause analysis:

Aging of pump diodes (lifespan of about 20,000 hours, measured power < 80% of nominal power needs to be replaced)

Bundle end face ablation (a unique problem of multi-fiber pump structure)

Cooling efficiency decreases (water temperature > 28°C triggers power derating)

Our innovative maintenance technology:

Diode group intelligent reorganization technology

Detection of failed single tubes in 6 groups of pump sources, and reorganization of the remaining 5 groups of drive circuits (avoiding the replacement of the entire group, saving ¥18,000)

Bundle end face reprocessing

Laser cladding repair technology is used (cost ¥5,000 vs. original factory replacement ¥25,000)

2. Water cooling system alarm (ALM 05/07)

Optimized maintenance strategy:

Fault point Traditional solution Our company's cost reduction solution Cost comparison

Water pump stuck Replace the original pump (¥8,000) Domestic magnetic pump replacement (¥2,500) ↓68%

Flow sensor failure Replacement of the entire module Cleaning the Hall element + calibration (¥300) ↓90%

3. Beam quality degradation (M²＞2.0)

Quick recovery solution:

Fiber bending detection: Ensure that the transmission fiber bending radius is ＞15cm

Collimator calibration: Use laser interferometer adjustment (accuracy ±0.1mrad)

Output head (QBH) cleaning: Special fiber cleaner treatment (no alcohol wiping)

III. Preventive maintenance system (reducing sudden downtime by 70%)

1. Intelligent health monitoring system

Real-time monitoring parameters:

Pump current fluctuation (early warning diode aging)

Spectral width (＞5nm indicates fiber damage)

Case effect: A customer's annual downtime due to failure was reduced from 23 days to 7 days

2. Key component life management

Component Standard life Our company's life extension solution Effect

Pump diode 20,000h Dynamic current regulation technology +30% life

Transmission fiber 3 years Stress monitoring + dustproof packaging Extended to 5 years

IV. Case study on cost reduction and efficiency improvement

1. Repair cost comparison

Repair item Original quotation Our solution Savings

6kW laser module ¥280,000 ¥95,000 ¥185,000

Control motherboard ¥65,000 Chip-level repair ¥8,000 ¥57,000

Annual comprehensive cost ¥500,000+ ¥150,000 ↓70%

2. Efficiency improvement data

Cutting speed optimization: Through pulse waveform library matching, stainless steel cutting efficiency increased by 18%

Equipment utilization: from 82% to 94% (preventive maintenance + quick response)

V. Our technical barriers

Chip-level maintenance capabilities: can repair precision components such as FPGA/DSP (less than 1% of enterprises in the industry master it)

Domestic spare parts certification: pump source/optical lens passed 2000 hours aging test

Process database support: built-in 100+ material processing parameters, debugging time shortened by 50%

VI. Service commitment

48-hour emergency response: supported by 7 major spare parts centers nationwide

Repair warranty period: 12 months (equivalent to original factory standards)

Free value-added service: provide "MFPT-M+ Power Optimization Manual"
