The edges of an oxyfuel gas cut are generally very rough.

The edges of an oxyfuel gas cut are generally very rough.

• A. True
• B. False
• C. It depends on material
• D. They are generally smooth

Answer: (B)

Oxyfuel cutting edge quality depends on how the cut is performed. The process creates a kerf and slag, which often sits on the underside and can make the edge feel rough. But the top edge can be fairly clean if preheat, torch height, and cutting speed are set correctly. Because roughness isn’t guaranteed and varies with material thickness and technique, saying the edges are generally very rough is not always true. If slag does form, removing it afterward is common to achieve a smoother edge.
