More welders are realizing the benefits of using plasma technology to perform gouging in heavy industrial applications where versatility, speed, and safety are important.
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.

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.

Combination machines have brought the done-in-one concept to the heavy plate fabricator's shop floor.
Time spent on extensive weld prep easily can eliminate any gains made from faster plasma cutting. Put another way, it doesn't matter how fast a plasma cuts if the resulting cut face can't be welded efficiently.

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.

Denman & Davis calls itself the largest general-line, independent service center in the Northeast. The company has about 65,000 square feet of inventory and manufacturing space in Clifton, N.J., another 70,000 square feet in Slatersville, R.I., and another 35,000 in Albany, N.Y. The company distributes a variety of hot-rolled and cold-finished bars, structural shapes, sheets, and tubing, but has discovered a fruitful niche with plate, used in pressure vessel, power generation, and processing applications.

Plasma cutting is a widely used process in the welding industry that provides both speed and precision, but it doesn't happen by accident. Being knowledgeable about your cutting applications, and familiarizing yourself with cutting techniques, maintenance, and safety features, will allow for a productive plasma experience.
