What occurs if the cutting speed during oxyfuel cutting is excessively slow?

When the cutting speed during oxyfuel cutting is excessively slow, it significantly impacts the quality of the cut. A slow cutting speed means that the oxygen and fuel are applied to a smaller area for a longer duration, which can result in the base material overheating. This excessive heat can lead to the formation of more slag, which is the molten material that is expelled from the cut, and it can also cause poor cut quality.

With a slow cutting speed, there may be an uneven cut surface, increased warpage, and an inability to maintain a straight cut. All of these factors contribute to an overall degradation in the quality of the cut, as the excessive slag can interfere with the desired cutting dimensions and finish. Thus, maintaining an appropriate cutting speed is crucial in achieving clean and effective cuts without excessive slag accumulation.
