摘要

PLASMA cutting of metal plate, tube, and pipe is nothing new-it has been in commercial use since the late 1950s. The process evolved from the gas tungsten arc welding (GTAW) process. Its development was based on implementing various combinations of gas flows and power levels to sever electrically conductive metals. Plasma relies on an electric arc that superheats an ionized gas stream to create a high-velocity, high-temperature jet that melts and expels molten metal. Some plasma systems use a shielding gas to assist with cooling consumables and constricting the arc. The shielding gas also improves the workpiece's edge metallurgy.
