Procedures Review Process

All welding procedures shall be sent at procedures@cwbgroup.org.

You will get a reply confirming the reception of your email by CWB.

All welding procedures should be submitted in PDF and not secured.

A review letter will be sent when the review will be completed.

There are three possible outcomes:

  1. Welding procedures have been accepted
  2. Welding procedures requires qualification
  3. Welding procedures requires revision

Turnaround time is three working days.

When PQR results are completed, a review letter confirming the test results will be sent.

Corresponding welding procedures will then have to be revised as per the PQR and returned to the procedure department for final review/acceptance
