Methods to reduce slag during plasma cutting include:
1. Adjust cutting parameters: Plasma cutting parameters such as current, voltage, gas type, flow rate, etc. will affect the generation of slag. Slag production can be reduced by reducing the current, increasing the voltage, and using the appropriate gas type and flow rate.
2. Increase the concentration of oxygen in the protective gas: During the plasma cutting process, increasing the concentration of oxygen in the protective gas can make the cutting speed faster and reduce the generation of slag.
3. Reduce the cutting speed: Reducing the cutting speed can make the plasma arc more concentrated and reduce the generation of slag.
4. Reduce the distance between the cutting torch and the workpiece: Reducing the distance between the cutting torch and the workpiece can increase the energy of the plasma arc, make cutting more stable, and reduce the generation of slag.
5. Choose high-quality pipes: Using high-quality pipes can reduce the generation of slag. It is recommended to choose a pipe supplier with a reputable manufacturer to ensure that the raw materials and production process meet the standards.
6. Strengthen cleaning: The cut pipes should be cleaned promptly after use to remove slag and oxides inside the pipes to avoid corrosion inside the pipes. If there is residue at a large angle inside the pipe, it can be removed using high-pressure water flushing or mechanical equipment.
7. Control the slag hanging phenomenon: The slag hanging phenomenon is also a reason for the generation of molten slag. The occurrence of slag hanging can be reduced by adjusting the cutting torch speed and using consumable parts.
In summary, methods to reduce plasma cutting slag include adjusting cutting parameters, increasing the concentration of oxygen in the shielding gas, reducing the cutting speed, reducing the distance between the cutting torch and the workpiece, selecting high-quality tubes, and strengthening cleaning and control Methods such as slag hanging phenomenon. These methods need to be applied flexibly based on the actual situation.
