“10000 watts” is undoubtedly one of the hot spots in the laser industry in the past two years.
At present, 10000 watt laser has gradually been recognized and affirmed by the market.
During this period, we received some users’ comments on the difficulties encountered in the commissioning of 10000 watt laser cutting.
In order to solve these difficulties, we sort out some common problems and give corresponding solutions for your reference.
Commissioning method of cutting process of thick carbon steel plate
1. For fiber laser cutting machine with different power over 10000+ watt, first, refer to the cutting process parameter table to debug the bright surface of the thickest carbon steel and stabilize the effect of machining the thickest carbon steel.
2. After adjusting the perforation process parameters, the effect and efficiency meet the requirements.
3. After the cutting and perforation process is adjusted, small batch cutting is required to verify the consistency of the process and effect.

| 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
Commissioning method of cutting process of thick stainless steel plate
1. For lasers with different power over 10000+ watt , refer to the laser cutting process parameter table, first debug the cutting effect of stainless steel with different thickness;
2. After adjusting the perforation process parameters, the effect and efficiency meet the requirements.
3. After the cutting and perforation process is adjusted, small batch cutting is required to verify the consistency of the process and effect.

| 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 |

Test method for cutting stability
In order to ensure the stability of equipment during batch processing and the stability of processed product quality, stability tests need to be done before 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. | |||
