Metal fabricators with plasma cutting equipment that is 10 years or older may be surprised to learn just how far plasma cutting has come. The technology has evolved to the point that outside edges are smoother than ever, and precision holes can be cut to accommodate fasteners.

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.

The methods used to shield the plasma arc from the atmosphere have evolved. The concept of using tap water to generate the secondary gas has been around for more than three decades, but high-precision plasma cutting using the nitrogen-water process was developed less than a decade ago.

High-density plasma arc cutting can effectively cut thick plate. The most challenging aspect, in fact, is that initial pierce. To that end, a few basic strategies help overcome this challenge, allowing the plasma to pierce through inches of metal as effectively as possible.

Como puede decírselo cualquier fabricante de metal, un taller es tan eficiente como todos sus procesos en conjunto—no sólo uno.

Plasma beveling technology has progressed in recent years to the point where the degree of taper has been reduced greatly and the ability to achieve predictable results, cut after cut, is possible. Having said that, a knowledgeable equipment operator can have a tremendous impact on optimizing the equipment's performance.

In any discussion about how to cut metal, plasma cutting is right up there with laser and waterjet. The technology gets a bad rap, though, when the discussion turns to cutting aluminum. There are five preconceptions that many fabricators have about turning to plasma to cut aluminum. But according to three experts, new plasma cutting systems produce good results on aluminum.
