Alone or assisted with water, plasma has proven itself to be one of the most efficient cutting processes for sheet, plate, tube, pipe, and profiles. Search this technology area for information on equipment, cutting tips, and gases.

The first plasma arc cutting (PAC) systems, developed in the '60s, were 1,000-amp monsters designed to blast through 6-inch stainless steel.

This study conducted at Hypertherm characterizes thermal and chemical changes in plasma-cut stainless steel and aluminum alloys and recommends process alternatives that may improve aesthetics and cut quality to improve forming and fabricating of the materials. The systems used were water-injection PAC, conventional dual-gas PAC, and high-precision PAC. It was learned that the heat-affected zone (HAZ) is small in plasma-cut pieces, HAZ varies with speed and power, faster cutting produces less HAZ, and more heat per square inch can produce less HAZ.

To clean-cut stainless steel sheet and plate, fabricators first must choose the right CNC cutting equipment and then set the correct process-related variables. Precise machine motion controls, torch-to-material distance control, and the correct plasma and assist gases all are crucial to producing weld-ready plasma-cut edges on all stainless steel thicknesses.

Attention to detail at the outset can save plasma cutting operators a load of trouble during production.
