Laser cutting uses laser energy to cut down the metal to reach the aspired workpiece. For example, metals such carbon steel, stainless steel, etc. the illuminated metals are rapidly melted, vaporized, ablated, or reach the burning point, and the melted materials are departed off by a high-speed airflow coaxial with the laser beam, to get the cut workpiece.
If the laser cutting procedure is strict i.e. controlled during the cutting process, the cutting quality can be maintained. These are the most important procedure parameters that affect the quality of the material.
Several factors go into the laser cutting process, including the cutting speed, laser power, the core position, the reserves of gas pressure, the shaft length, and the shaft diameter.
But during the process of cutting metal with a laser cutting machine, various problems can occur, which seriously affects work efficiency.
Burning in laser cutting is also a major problem. When you cut wood materials there are high chances of burning. But if you know the reason behind then you can prevent burning during the laser cutting.
How should we overcome it?
We regularly say: under ordinary cutting conditions, the impact of cutting (as shown below) ought to be no slag on the metal edge, The cutting lines are in line.
But, in the actual operation of misappropriate debugs, 90% of the problem arises.
Here additionally we have given the solutions to these issues. This blog will summarize some solutions to the common problems in metals laser cutting.
Problem1: The lower part of the spaceline has huge steady, the lower part of the incision is more extensive
Maybe caused by
- The feed rate is excessively high
- laser power is excessively low
- Low air force
- The core is excessively high
Solutions
- Reduce feed rate
- Increase laser power
- Increase air force
- Reduce focus
Problem 2: The burr on the underside is like molten slag and is effortlessly removed by a drip.
Maybe caused by
- The feed rate is excessively high
- Low air force
- The focus is excessively high
Solutions
- Reduce feed rate
- Increase air tension
- Reduce focus
Problem 3: The metal burr that is blended can be reduced as a whole block.
Maybe caused by
- The center is excessively high
Solutions
Problem 4: Metal burrs on the underside are difficult to reduce.
Maybe caused by
- The feed rate is excessively high
- Low air force
- Impurity at gas
- The center is excessively high
Solutions
- Reduce feed rate
- Double the atmospheric force
- Use of disinfectant gases
- Reduce center
Problem 5: Only Burr on the side of the plate cut.
Maybe caused by
- Incorrect spile adjustment
- Defective spile mouth
Solutions
- Use of the core spile
- Changing spile
Problem 6: The material is issued from a higher place.
Maybe caused by
- Low force
- The feed rate is excessively high
- Improper utilization of reserved gas or gas obstruction
Solutions
- Quickly press the pause catch to keep the slag from sprinkling onto the laser protection lens.
- Then increment the power and decrease the feed rate.
- Check the usage of reserved gas to find accuracy and sensible change correction.
Problem 7: Metal did not slice through.
Maybe caused by
- Processing gas blunder (N2)
- The feed rate is excessively high
- Low force
- Improper utilization of reserved gas or gas blocked status
Solutions
- Press the pause button quickly to keep the liquid slag from sprinkling onto the laser protection lens.
- Use of oxygen as a procession gas
- Reduce feed rate, increment of power
- Check the use of reserved gas and reasonable change correction.
Problem 8: The cutting surface isn’t exact.
Maybe caused by
- The air tension is excessively high
- The spile is harmed.
- Spile width not proper
- The material surface has the rust dent or the damage is not dangerous
Solutions
- Reduce gaseous tension
- Replace spile
- Install right spile
- use smooth and uniform surface materials
Problem 9: Without burrs, the spaceline slants, the cut becomes smaller at the base.
Maybe caused by
- The feed rate is excessively high
Solution
Problem 10: Cutting the surface is unpleasant.
Maybe caused by
- The middle is excessively high
- The air force is excessively high
- Low feed rate
- The material is excessively hot
Solutions
- Reduce core
- Reduce atmospheric force
- Increase feed rate
- Use cooling material
Conclusion:
These are the main problems we found during the laser cutting and the above are the possible solutions listed above. If you find any other problems in laser cutting and know the solutions then share with us in the comment below.
