Radiograph 1" plate test 3g

Welding Certification test Q&A and tips and tricks

Thanks for the advice, im pretty sure I have to test dc reverse polarity. Will try the lead wrap idea, ill try anything at this point. Im actually the only one welding at this point, so ive actually tried different machines and different booths with no change. I have the coupon tacked hard at the top with the ground clamp above it normally. Everything was going great until a couple weeks ago when I started having this problem. When welding the root I can get within an inch of the top of the coupon, then arc blow. I've learned that I can drop my elbow and get the rod angle steeper and work it and I can get to the top. However it looks hideous, and im afraid it may not be clean weld. Not sure. Ive never taken an ex ray test, not sure if that portion would pass.

Don't be afraid to fail. You can always try again.
I have more questions than answers

You're absolutely right, I guess when you put so much time into something you pressure yourself to the point where nothing but perfection will do. Pass or fail I am twice the welder I was a year ago, and confident enough to say so.

Well thanks for that, however I've been wrestling with this since I replied to Poland. I would say to not be confused with 'don't be afraid to fail' with 'its ok to fail'. Big difference. A lot of us, including myself weld for a living, this test could mean a job which feeds my family. Its not ok to fail. If I fail this test, to retest it requires an additional fifty hours of training before retest. Which would take place forty five minutes from home, hopefully after eight hours of work, if the Instructor had time and chose to hold the class. So after rethinking this, I think a prudent person would be afraid to fail, and I m ok with that. Just a side note, God bless my instructor, he's fantastic.

I understand that, too.

I've driven 1300 miles for a make or break test more than once.

I've failed one, too.

That's a quiet ride home... I don't even want the radio for companionship at that point.

So the test was saturday may 7th. I've had some time to think about it now, its been over a week. I'm confident, but a little reluctant to celebrate. I didn't have any major issues while welding. I won't get the results back for couple more weeks, they get sent to the state capitol where they are measured and ex rayed. Just a note to other students out there, work hard and you will see improvement. It may be frustrating at first but it gets better, stick with it.

Havnt followed this thread but just caught up on it. Sounds like you got it. A lot of times when you're frustrated like that you have to take a break and come back. But your mind tells you to try again. Ive only failed 1 cert and that was my stainless pipe 6g. Purge fell out and I couldn't redo it. Auto fail. Worst 3hr drive of my life. If you don't make it, just take a breath and go at it again. I would try to weave as much as I could as it burns hotter and seems to leave less crap in there. But stringers are quick and get the job done too. Just gotta get the smooth motion down. I hope the results then out well in your favor. Good luck

When I fail I blame it on the welding machine, the rod, the position of the moon. It happens, anyone tells you it doesn't they are full of it. Nothing worse than doing a heavy wall 6G and the inspector says "you will not radius the corners on the straps", edges are a crap shoot sometimes.

One thing I can be for sure of, a picture of that Alaskan fellas root pass belongs in a welding text book.

I can relate to blaming the moon phase. I can blame a machine, in one case, because of a gas coverage issue, but that's still on me, for not recognizing it at the time.

If by "that Alaskan fella", you mean John, AKWeldshop, you'd be stunned by how young this exceptionally talented fellow is.
