| Thickness&surface | Problem | Solutions |
|---|---|---|
| 25mm bright surface 30mm bright surface 40mm frosted surface | Cutting nozzle heating | 1. Increase nozzle size |
| 2. Clean the lens if the lens is dirty | ||
| 3. Lower the cutting focus | ||
| Rough cutting surface | 1. Raise the cutting focus | |
| 2. Reduce nozzle size | ||
| 3. Reduce cutting gas | ||
| 4. Increase cutting speed | ||
| Cutting slag hanging | 1. Improper cutting speed | |
| 2. Increase the cutting air pressure | ||
| 3. Improper cutting focus | ||
| Inconsistent cutting surface | 1. The nozzle outlet is not round | |
| 2. The laser is not in the center of the nozzle |
16-40mm carbon steel cutting effect
Common Problems and Solutions Table for Debugging Cutting Stainless Steel with 10,000+ Watt Lasers
| Thickness&surface | Problem | Solutions |
|---|---|---|
| 6mm: no slag hanging 20mm: slag point | Cutting layered | 1. Reduce dam cutting speed |
| 2. Increase dam cutting pressure | ||
| 3. Increase the size of nozzle | ||
| 4. Improper cutting focus | ||
| slag hanging | 1. Improper cutting speed | |
| 2. Increase the cutting air pressure | ||
| 3. Reduce the negative focus | ||
| Slow efficiency | 1. Dirty lens | |
| 2. Increase the cutting air pressure | ||
| 40mm: small amount of slag hanging | Cutting layered | 1. Reduce frequency |
| 2. Raise the positive focus | ||
| 3. Increase the cutting pressure | ||
| Yellow cutting surface | 1. Reduce the duty cycle | |
| 2. Raise the positive focus | ||
| 3. Increase the cutting air pressure |
10-70mm stainless steel cutting effect
To ensure the stability of the equipment during mass production and maintain consistent product quality, stability tests should be conducted prior to formal batch processing.
Test method for cutting stability of 10000 watt laser
| Testing material | 6-10mm stainless steel | Test graphics | Helical line |
|---|---|---|---|
| Testing time | 5-10min | Test gas | Nitrogen |
| Testing method | 1. Adjust the stainless steel cutting parameters to ensure that the cutting surface is free of slag and stratification | ||
| 2. Cut continuously at full power for 5-10min to check whether the cutting surface is consistent; | |||
| 3. In case of increasing slag hanging, blue light after cutting for a period of time, continuous cutting and other problems, it indicates that the cutting focus is offset. It is necessary to check the cutting head lens (dirty lens, poor lens quality, thermal lens problem) and the focus position. | |||
