4T.02 Cut Quality
NOTE!
Cut quality depends heavily on
setup and parameters such as torch
standoff, alignment with the work
-
piece, cutting speed, gas pressures,
and operator ability.
Cut quality requirements differ depending on applica-
tion. For instance, nitride build - up and bevel angle
may be major factors when the surface will be welded
after cutting. Dross - free cutting is important when fin
-
ish cut quality is desired to avoid a secondary cleaning
operation. The following cut quality characteristics are
illustrated in the following figure:

Cut Quality Characteristics
Cut Surface
The desired or specified condition (smooth or rough)
of the face of the cut.
Nitride Build - Up
Nitride deposits can be left on the surface of the cut
when nitrogen is present in the plasma gas stream.
These buildups may create difficulties if the material
is to be welded after the cutting process.
