You can use similar WPS / procedure for welding A333 grade 6. But in
my opinion it is only possible to use a PQR made in material A106
grade B for welding A333 grade 6 when impact tests are performed on
the test weld. This normally is required for A333 Grade 6 material and
such test is mostly not performed on an A106 grade B test weld.
If there are no impact requirements than you may use the A106 PQR.
