What Are The Most Common Issues in Laser Cutting?

I. Judgment and treatment methods of laser cutting stainless steel section

In a recent incident at a manufacturing plant, black edge marks were discovered on the lower surface of the products being produced. An investigation revealed that this issue was caused by excessive power or slow speed during the manufacturing process. The quality control team immediately implemented measures to rectify the situation and ensure that future products meet the required standards.

Furthermore, another issue was identified in the form of white and bright areas on the lower surface that were not properly cut through. This was accompanied by hard slag in the lower area and a downward movement of the focus. In response to this, the manufacturing team took action by adjusting the focus and increasing the speed of the production line.

Additionally, granular soft slag was found on the lower surface of some products, prompting the team to make further adjustments. By increasing the speed and reducing the air pressure, they were able to eliminate the issue and improve the overall quality of the products.

Lastly, burrs were observed on the lower surface of certain products, indicating a need for increased air pressure and a downward adjustment of the focus. These corrective measures were swiftly implemented to address the issue and ensure that all products meet the required standards of quality.

the manufacturing plant successfully resolved these issues through proactive measures and adjustments to the production process. By addressing these challenges head-on, they were able to maintain high standards of quality and efficiency in their operations.

The laser focus is crucial to the section. There is a gap in the focus position of different cutting heads, so you need to adjust the focus range position to suit yourself.

II. Selection of commonly used nozzles in laser cutting process

The single-layer nozzle is a common choice for cutting materials such as stainless steel, galvanized sheet, and aluminum sheet with air or nitrogen. It is widely used in various industries for its efficiency and precision in cutting these materials.

On the other hand, the double-layer nozzle is specifically designed for low-power oxygen cutting applications. It is suitable for cutting various materials with oxygen and is a reliable option for achieving clean and accurate cuts.

For high-speed cutting of carbon steel, the high-speed single-layer nozzle is the preferred choice. It provides a more stable performance compared to other nozzles and is capable of cutting high-power with oxygen negative focus, making it ideal for bright surface cutting applications.

Similarly, the high-speed double-layer nozzle is used for oxygen positive focus cutting of bright surfaces, ensuring excellent cutting results on a variety of materials.

The storm nozzle, also known as the booster nozzle, is designed for cutting stainless steel and carbon steel with high-power nitrogen or low-pressure air. It offers superior cutting performance for these materials and is a popular choice in industries that require high-quality cuts.

the selection of the appropriate nozzle is crucial for achieving optimal cutting results in various applications. Whether it is for cutting stainless steel, aluminum, or carbon steel, there is a specific type of nozzle that is best suited for each material and cutting requirement.
