Chapter 14 Oxyfuel Gas Cutting 423 Bevel angles can be cut at the same time the metal is being cut to size and shape. A chamfer can also be cut as a separate operation, however. The technique used to cut a bevel is similar to the technique used to cut thick metal. However, the torch is held at an acute angle to the base metal, and the cut is generally made at an existing edge of the metal. It is important to obtain a high-quality cut when making the bevel. This minimizes any further plate preparation and ensures a good fi t-up of the joint to be welded. Figure 14-29.
