Home News Efficiency first - 5 common laser metal ...

Laser cutting is the most important application technology in the laser processing industry. It is also the earliest and most used processing method in laser processing. Because of its many advantages, it has been widely used in automobile manufacturing, aviation, shipbuilding, railway equipment, industrial automation, national defense, building materials and other industries. With the advantages of accurate, fast, simple operation and high degree of automation, laser cutting has become the first choice for manufacturers in the above industries to improve metal processing efficiency.



1. Soft slags that can be removed at lower surface

Causes: Cutting speed is too fast; Focus height is too high; Gas pressure is too high

Solutions: Lower cutting speed; Lower focus height; Lower gas pressure


2. Coating peeled off at the lower edge

Causes: Gas pressure is too high; Focus height is too low; Cutting speed is too fast

Solutions: Lower gas pressure and cutting speed; Increase focus height


3. Hard slags at the lower surface of stainless steel sheets

Causes: Focus height is too high; Gas pressure is too low; Cutting height is improper

Solutions: Lower focus height; Increase gas pressure; Adjust cutting height


4. Abnormal color of the edge

Causes: N2 is not pure

Solutions: Change to pure N2


5. Abnormal defect at starting cutting point

Causes: Wrong setting of laser on/off delay; Improper cutting lead

Solutions: Apply different lead line; Reset the laser on/off delay


For metal fabrication or manufacturing companies, it is crucial that laser cutting processing is not bothered or shut down by abnormal cutting defects. A stable, good-quality, and efficient laser cutting machine by a trustworthy company is what they truly need. And, we also keep an eye out for those common cutting defects, because laser cutting machines are still complex equipment that requires regular and careful maintenance.
