Which property of materials can impact the quality of oxyfuel cutting?

The quality of oxyfuel cutting is significantly influenced by the material surface condition. A clean and properly prepared surface allows for more effective oxidation during the cutting process, ensuring that the flame can penetrate the metal uniformly. Contaminants such as rust, paint, or oil can create barriers or interfere with the reaction, resulting in an uneven cut or poor-quality edges.

When the surface is free of impurities, the cutting torch can perform optimally, producing a clean and precise cut. In contrast, a poor surface condition may lead to issues such as slag formation or incomplete cutting, ultimately affecting the integrity and quality of the finished workpiece. Therefore, maintaining a good surface condition is essential for achieving the best results in oxyfuel cutting.

Other factors, although relevant in different contexts, do not directly impact the cutting quality to the same extent as surface condition does. For example, material weight and length could influence transportation and handling but have a negligible effect on the cutting quality itself. Similarly, the age of the material may affect certain properties, but it is not a primary concern like surface preparation is in oxyfuel cutting operations.
