Plasma cutting for tube, pipe, profiles

July 11, 2013 | By Jim Colt

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.

Don't rule out plasma for cutting aluminum

January 27, 2009 | By Michael Bishop

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.
