Now, is it really so incredibly difficult that you can't do that?

It will be if he can't first establish a PQR.

If he uses a WPS, is a PQR required? Not to say he doesnt have one!

Yes, a PQR is required for a proper WPS.

A PQR is the record of the design stage weld that is tested, and how the weld was performed. After it is determined the produced test weld is sufficient, the WPS provides a weld operator with the information necessary to reproduce the results of the tested welded joint.

[edit] For a better worded explanation, I went to Wiki: The AWS defines welding PQR as a record of welding variables used to produce an acceptable test weldment and the results of tests conducted on the weldment to qualify a Welding Procedure Specification.

Welding Procedure Specifications (WPS)

This document details the practical application of the Procedure Qualification Record (PQR). It should contain enough information to give direction to the welder and should address all variables associated with the welding process defined in QW250 including non essential and supplementary.

A WPS can combine welding processes from many PQR's but all the relevant variables must be addressed including parent metal thickness. There is an exception to this rule for root runs from PQR's that are greater than 1.5 inches thick (38.1mm), see code for details.
