I hold an all position SMAW structural ticket with the Canadian Welding Bureau (CWB). CSA standard W47.1 class S
This was done on 3/8" plate and qualifies me for 3mm-unlimited thickness carbon steel.
The first time you do this test, you do all 4 positions. 2 years later to renew the ticket you do one plate. Vertical up root on the square side then over head for the rest of the plate.
You can use a wire wheel but no grinder. All 1/8 7018 rod.
