OLC stands for which cutting method?

• A. Oxygen lance cutting
• B. Oxygen laser cutting
• C. Optical line cutting
• D. Oxygen lever cutting

Answer: (A)

OLC stands for oxygen lance cutting. This is a gas-cutting method where a lance delivers a high-velocity stream of oxygen to the preheated metal surface. The oxygen reacts with the hot metal, forming iron oxide that is blown away by the jet, creating the cut (kerf). This is a common technique in oxy-fuel cutting, especially for ferrous metals, where the flame preheats the metal and the oxygen sustains the oxidation to cut through. The other terms aren’t standard for this process: a laser cutting method would use a focused laser beam rather than an oxygen jet; optical line cutting and oxygen lever cutting aren’t recognized cutting methods in welding theory.
