welding operator performance test for hard facing

[stanweld99]

For machine welding operator qualification test on hard facing, does it have to be with the hard facing procedure per QW-453?
Are operators qualified from groove weld procedure (since P and F number are not essential variables for machine welding) qualified for hard facing?

Thanks for the input and help.

Groove weld qualification does not qualify the welder for hard surfacing or corrosion resistant weld overlays.

Hard facing is no - corrosion resistant overlay is maybe

QW-381.3 Alternative Qualification With Groove
Weld Tests. When a chemical composition is not specified
in the WPS, welders or welding operators who successfully
complete a groove weld performance qualification
test meeting the corrosion‐resistant overlay bend test requirements
of QW-163 may be considered qualified for
corrosion‐resistant overlay welding within the ranges defined
in QW-350 or QW-360.
