Well, here's my first bend test in an attempt to get my MIG cert. The first time I tried it, the face bend was fine, but here is the result of the root bend. Obviously, I'd rather pass without resorting to technicalities, but since there ARE small allowances, I'd like to make sure they are being interpreted and applied completely to my test.Basically, the way I understand the code, it seems like this should have passed. The only crack on the actual face, as shown, is 3/32". I thought cracks on the sides were not included. If someone can clear this up for me, I'd appreciate it. Thank you.http://imageshack.us/g/833/014mrx.jpg/Last edited by Migmark; 05-07-2013 at 09:01 PM.
Reply:From what I remember you would have failed.   What position?
Reply:All the tests I have done you are allowed a 1/8" defect. Hold a 1/8 stick rod on top of the defect. If you see the defect on either side of the 1/8 stick rod, you fail. If you don't, it's ok. Was this a flux core test? It looks like a buried piece of slag that you missed  cleaning and opened up.JasonLincoln Idealarc 250 stick/tigThermal Dynamics Cutmaster 52Miller Bobcat 250Torchmate CNC tableThermal Arc Hefty 2Ironworkers Local 720
