PROCESS
EROSION
Using high speed liquid and
garnet abrasive.
BURNING/MELTING
Using a high
temperature ionized gas arc.
MELTING
Using a concentrated laser
light beam.
EROSION
Using an electrical discharge.
SECONDARY PROCESSING
Usually none. Waterjet is
a cold-cutting process that
leaves a satin smooth edge.
Typically yes. Slag grinding
for removal of HAZ (heat
affected zone) & flattening
to eliminate distortion from
heat. Assist gas used
impacts depth of HAZ
Sometimes yes. Removal
of oxidized edge and HAZ.
Gases used impact depth of
HAZ.
Usually none. Very shallow
HAZ imparted.
MATERIAL
Virtually any material. Primarily steel, stainless
steel and aluminum.
A variety of materials,
but primarily steel, stainless
steel and aluminum.
Conductive materials.
THICKNESS
Up to 120 mm 76 mm, depending on
the material.
Generally 26 mm or
less, depending on the
material.
Generally 304mm or less.
CUTTING ACCURACY
+/- 0.005 +/- 0.10 +/- 0.005 +/- 0.005
