A few weeks ago, Dan Shewfelt, my business partner, and and super smart welding guy, gave us a blog about CSA W47.1 Option 3 testing. Now, I am not a welder, but it seemed a little complicated and hard to follow. But it isn’t! So we worked a bit more on it, added lots of photos and have completed re-done the blog!
CSA W47.1 Release 2015 has removed the option for Mechanical testing (Side Bends) of 1/2″ FCAW/MCAW welder Testing. It was super easy to pass, and there were legitamate reasons to remove this option. The problem we are seeing in our test centre is that FCAW/MCAW typically is tested with 0.045″ Wire. In the standard option 1, 3/8″ test assembly, the gap is only 5/16″, making the horizontal FCAW/MCAW test, nearly impossible to pass.
So, we needed a solution, and after checking out the code, we found a solution!
CSA W47.1 Figure 8 Option 3
This is the code diagram for Option 3. Plate size, and joint preparation is given.
These are available for purchase at AXIS Inspection
Once you have your plates, and are ready to test:
Tack the back of the beveled plates ensuring good joint fit up.
The CWB Will then Mark the test plate to indicate Stop/Start Location. Note there is only 1 stop/Start for this test. The plate will be marked for the welder’s preferred welding direction. Left to Right, OR Right to Left. (This plate has been set up for a Left Handed Welder)
The welder now welds up to the indicated “Stop” Mark. The CWB Rep will now check this first pass.
This is the first Stop/Start Completed. After this pass, there will be a Fill pass (Not shown)
Fill up the plate, (Should only require 1 more pass)
Now Flip the plate over and Grind to Sound Metal (GTSM) Note the CWB Rep is to be watching this process to prevent excessive grind depth.
Grinding depth shall not exceed 1/8″. This will remove the tacks, the Stop/Start will be ground from the backside to ensure full penetration of the weld joint.
Fill back side of plate. This should only require one pass.
This is a completed CSA W47.1 Option 3 Test assembly. This entire test, including wait times, took 25-30 minutes.
This (if passed) would give the welder a bevel ticket. But, let’s face it, you also need the fillet ticket.
CSA 47.1 Option 6 indicated the testing requirements for a Fillet test.
First you need your materials. Which are 2 plates, 6″x6″x 3/8″ (or 150mmx150mmx10mm) which can be ordered at AXIS Inspection
Ensure that fillet weld assembly is tacked at 90 degrees! Proper Fit up is as important as good welding, take the them to ensure your joint is accurate before welding!
The CWB will mark the Test Assembly with one Stop/Start and you are ready to weld.
Begin welding to you Stop Point. At this time, the CWB rep will check your weld and advise you to continue.
Complete your pass. and this is all that is required for the Fillet Test!
Measure fillet weld, using a Fillet weld gauge to ensure that the weld does not exceed 8mm
You are done! Now the Test Assemblies are send for mechanical test, and will be marked for testing.
The Option 3 test plate is marked for 2 Root and one Face Bend and the Fillet weld assembly, will be marked for one Fracture and two macro Etch tests.
