Frequently Asked Questions

Do I have to re-certify my company?

No. The changes in CSA Standard W47.1-19 will not result in the need for the "Re-certification" of any clients currently certified to the 2009 edition. All clients now certified to the 2009 edition will be considered certified to the 2019 edition effective September 1, 2020. Certificates and Letters of Validation will not be reissued as they currently do not make reference to the year of the certification standard. All welder qualifications will be valid until the expiry date shown on the qualification and all existing CWB accepted welding procedures would remain CWB accepted indefinitely.

What if I am currently in "applicant" status, and not yet certified?

This change will not impact your application for certification to CSA Standard W47.1-19, as no additional requirements have been added. Your CWB Representative will continue to work with you to help you achieve certification for your organization.

Will the change in the standard impact my annual Fees?

No, the release of the 2019 edition will have no impact on your annual fees. Do I have to purchase a copy of the 2019 edition to maintain my certification? There is no requirement for existing clients to purchase the new version of the standard to maintain your certification. However, we encourage our clients to buy a copy of the latest edition to both be familiar with the changes and to take full advantage of some of the revisions to both welder and procedure testing options.

Do I have to retest my welders?

No, there is no requirement to retest any welding personnel (tackers, welders, and operators). Current qualifications will continue to be valid until the expiry date shown.

Do I have to resubmit my welding procedures?

No, there is no requirement to resubmit any welding procedure documentation (WPS and WPDS). All currently accepted documentation will continue to be considered approved. However, new welding procedure documentation submitted after September 1, 2020, should refer to the 2019 edition of the standard.

Note that beginning on June 1, 2020, any welding procedures submitted can be reviewed and approved in accordance with the 2019 edition at the option of the certified company.

I'm a Qualified Welding Supervisor / Welding Engineer. Do I have to rewrite my "code" examinations?

No, currently accepted Welding Supervisors and Welding Engineers will not be required to rewrite examinations on CSA Standard W47.1-19. Welding Supervisors and Welding Engineers seeking qualification will be examined to the 2019 edition beginning September 1, 2020. Examinations completed before this date will continue to be done to the 2009 version of the standard.

I'm a Certified Welding Inspector. Do I have to rewrite my "code" examinations?

No, Certified Welding Inspectors will not be required to rewrite examinations on CSA Standard W47.1-19. However, Welding Inspectors at all levels completing their initial examination on CSA Standard W47.1 & W59 will be examined to the W47.1-19 edition beginning September 1, 2020. Examinations completed prior to this date will continue to be done to the 2009 edition of the standard.

Training Courses

All Welding Supervisor Courses attended after June 1, 2020, will make reference to the 2019 edition of CSA Standard W47.1. Welding Supervisor "Study Guides" for the 2019 edition of CSA Standard W47.1 will be available for sale effective June 1, 2020.

My organization welds stainless steel.  Do I have to use the new Annex K for procedure and welder qualifications for stainless steel?

Yes, Annex K is a mandatory annex and the requirements of Annex K must be met if your organization’s scope of certification includes the welding of stainless steel.   However, stainless steel welder qualifications previously performed to the previous edition of CSA W47.1 (which referred to AWS D1.6) are still valid until their stated expiry date and can be renewed under Annex K.   In addition, any previous welding procedures accepted to the previous edition of CSA W47.1 (which referred to AWS D1.6) also remain valid for use.
