Fiber Optic Transmission System Maintenance —The Importance of Avoiding Bending and Cleaning Interfaces

The fiber optic transmission system plays a crucial role in the operation of a fiber laser welding machine, directly impacting the laser energy transmission efficiency and weld quality. However, many users tend to neglect fiber optic transmission system maintenance during daily use, leading to performance degradation or even equipment damage.

1. Avoid Fiber Bending to Ensure Signal Stability

Fiber optic transmission lines must maintain a natural bend during use, avoiding excessive bending or twisting. Excessive bending can attenuate the laser signal within the fiber and even cause fiber breakage, resulting in high repair costs. During installation and use, it is recommended to ensure that the fiber bend radius is no less than the manufacturer’s specified safety value, and to avoid heavy objects pressing on the fiber cable in the work area.

2. Clean Interfaces to Prevent Contamination and Damage

Clean fiber interfaces are also crucial. Tiny particles such as dust and oil can attenuate laser energy and even cause ablation under high-power lasers, damaging the interfaces. During routine maintenance, it is recommended to use specialized fiber optic cleaning tools, such as dust-free cloths and fiber cleaning pens, and avoid direct contact with the interfaces to prevent secondary contamination.

3. Regular Inspections to Extend Equipment Life

Users should establish a regular inspection schedule based on frequency of use, focusing on checking the appearance of the optical fiber, the condition of the interfaces, and whether the fixing points are loose. Preventive maintenance can effectively avoid equipment downtime and improve production efficiency.

The optical fiber transmission system is the core component of the stable operation of the fiber laser welding machine. Only by performing regular maintenance can the welding quality and equipment life be guaranteed.
