When inspecting cuts made with oxyfuel equipment, which characteristic should the drag lines ideally possess?

In the context of oxyfuel cutting, the presence and characteristics of drag lines can significantly indicate the quality of the cut. Ideally, drag lines should be minimal, as this reflects a more effective and efficient cutting process. When skilled operators use oxyfuel equipment, a clean-cut will result in less pronounced drag lines, suggesting that the cutting speed and the heat input were properly calibrated.

Minimal drag lines imply that the material was cut efficiently without excessive melting or distortion, leading to a more precise edge. A clean edge with few imperfections contributes to the integrity of any subsequent fabrication work that may depend on that cut. Therefore, ensuring that drag lines are minimal indicates quality workmanship and adherence to best practices in oxyfuel cutting.
