Plasma cutting
The hot concentrated jet produced by the plasma method, which has previously been
described in connection with welding, is very suitable for cutting. However, as opposed
to gas cutting, which works primarily by burning the material using the oxygen in the
cutting jet, plasma cutting works by melting the material and then blowing the molten
material out of the cut by the pressure of the plasma jet. When used for cutting, the pres-
sure of the plasma gas is higher than as used for welding, and both smoke and noise are
generated, at least when cutting thicker plate. However, this can be considerably reduced
by cutting the metal on a cutting table, with the metal itself under water.
The range of applications is wide, although materials of particular interest for this
process are such as stainless steel, aluminium and copper, which cannot be cut by
ordinary oxy-fuel gas cutting.
