Initially used for nonferrous cutting operations, plasma developed into a useful means for cutting 2-D sheet and plate steel when the water-injected plasma process was developed in the late 1960s. As technology developments improved the edge quality, cutting speed, consumable parts life, and long-term operating cost, it became competitive with other thermal cutting processes. In recent years, improved control technology has enabled plasma to be a contender in the realm of 3-D cutting, making it an option for tube, pipe, and profiles.
