Those Canucks take their welding seriously

Paul,
I know what you're thinking, another early Saturday morning question.
I've been looking at the requirements of obtaining a CWB inspector certification. Am I seeing this correctly? A CWB inspector can apply for a CWI by reciprocity by nothing more than an application and fees. But a CWI who wants to be a CWB, in this case a level 2, would fill out the application, pay fees, and still have to take an exam?
Doesn't strike me as "equivalent" or fair.

Tim,
Your assessment is correct.   For a CWB to apply for a CWI it’s just a fee and some paperwork.  For a CWI to apply for a CWB it’s a test.  Those Canucks take their welding seriously.
I was the Quality Manager in a pole manufacturing company that was CWB Certified.  Every 6 months I had to hire a CWB engineer to audit my organization (and it was an in-depth look at our welding).  There were a lot of hoops to jump through, but if we wanted to sell power-line poles in Canada it was a requirement.
I was also a contract CWI for a boss that was Canadian.  Anytime I mentioned my past work as a Welding Engineer he would go ballistic.  Calling yourself a Welding Engineer in Canada means you’ve met specific requirements in education and testing and if you referred to yourself as a Welding Engineer without meeting those requirements you could go to jail.
Some of the things I liked about working in a CWB shop: 1.) Welders had to retake their Welder Qualification Tests every 2 years.  I believe that helped maintain weld quality in our shop. 2.) Welder Qualifications were given using a Bevel Groove.  The first pass was a Fillet Weld of a specific size up against that square edge of the Bevel Groove.  The fillet had to have a restart in it. The location of the restart was marked, and 1 of the 3 required bend coupons had to contain that restart.
One of the things I didn’t like was that they consider FCAW and GMAW with a Metal-Cored wire (MCAW) the same process (for welder qualification purposes).  The Welding Engineer in me (said quietly so as not to be heard across the MN/Canadian border) sees these processes as requiring different skills.
When working in a shop that requires compliance to CWB and AWS this FCAW/MCAW thing reeks havoc.  In fact, when I showed up for my first week at this pole shop I learned that All of the Welders took a FCAW test to get their job, but the shop ran about a 50/50 mix of FCAW and GMAW using Metal-Core.  From a CWB perspective this was no “Biggie”, but from an AWS perspective (which was about 90% of what they did) no Welders were qualified for GMAW (and not one of the 4 CWI’s that worked there seemed concerned).  What a mess!
The way I turned that around was by using the CWB 2yr retesting requirement.  I gave MCAW tests, had them evaluated by the CWB to Canadian standards and evaluated them myself as a CWI to AWS standards.  At 6 month intervals, over a 2 year period, those Welder Qualifications were brought up to speed.
If I was an independent contract CWI I’d probably pursue the CWB route, but if you work in a shop that’s considering bringing in CWB work then CWB/CWI reciprocity is the least of your worries.

Just a side note from your friendly neighbourhood Canadian inspector.... FCAW and MCAW can be used with the same qualification, GMAW is a completely separate qualification. If welders are seen running GMAW with a FCAW/MCAW ticket during an audit, I assure you that all hell breaks loose!

Excellent analysis Paul !

I too admire the CWB for many things. The test assembly you posted is most excellent, although it's interesting that a 3/8" coupon will qualify for unlimited thickness.

I'm also impressed that the CWB came out in W47 a year or so ago and stated that GMAWP is a prequalified process. Something the AWS refuses to make clear.
