Final answer:
True, the edges of an oxyfuel gas cut are generally rough due to the high-pressure, high-heat method, and can vary depending on the type of metal and specific process used.
Step-by-step explanation:
The statement that the edges of an oxyfuel gas cut are generally very rough is True. An oxyfuel gas cut is a process used in metallurgical engineering to cut through steel and other materials. This technique involves combining a fuel gas with oxygen at high pressure. The heat produced is used to cut through materials. Its intensity can cause the edges of the cut to be very rough, especially if the operator is not very skilled.
This roughness is a result of the rapid oxidation process, high heat, and high pressure used in oxyfuel cutting. Further, the roughness of the cut can also vary depending on the type of metal being cut and the exact process being used in oxyfuel cutting. In contrast to other cutting methods like laser or plasma cutting, oxyfuel cutting typically results in rougher edges.
