Analysis of the Causes of Welding Failure in Welding Machines

DVP explained to everyone that the fusion machine failed to fuse and there were black spots at the fusion point to dispel doubts:

Possible issues with the fiber itself

Possible fiber end face unevenness or angle issues

Perhaps the high-voltage discharge is abnormal or the electrode rod is too dirty.

For troubleshooting, consider increasing the overlap length setting to 12 and try welding; Visually check if the discharge is stable, and pay attention to cleaning the fiber optic V-groove presser foot while ensuring the cutting angle of the cutting knife.

1. To determine whether it is single mode or multimode, the first step is to clean the optical fiber. Impurity caused by medical use of industrial pure alcohol may occur;

2. Also perform a discharge correction to correct the current;

3. Ensure that the cutting blade angle is below 3 degrees. First, try these methods, and then use other optical fibers for fusion to eliminate any fiber quality issues.
