    We are x ray'ing a weld tonight that has failed 6+ times, and has to ship by Monday, and still has a bit to go after it passes.

    DOH!!!! :doah:

    Don't you love it when a weld fails x-ray? It can ruin your day. Of course, I can't recall a time when one of ours has failed more than twice. Six times? What's the story behind that one, John?

    Do you have to pull an insert on this specific weld? That seems to be why most of ours fail. Our welders can not seem to pull an insert to save their lives:doah:. I love being the Quality Assurance Officer you get to tell people they ****in suck:haha:.

    Well, the story is it's for us , oversize. 46" diameter, 1 inch thick round seam that has been sub arc'ed. After the initial failure, we are only allowed to run mig as a stringer and sub arc fill and cap (not an option now, as there are nozzles sticking out) or 7018. So we have been going back in and digging out the defects, but then reintroducing new ones. The human variable with the manual process is kicking our butts. We are really not set up for anything this size. The completed bottle weighs 9000+ pounds!! The x ray has been completed, now we wait.

    46" ??????? :yikes:

    The biggest I go is 273mm(10"), other than a little bit of HP 12" that I really don't take care of anymore, unless it's an emergency.

    Is this a vessel you're talking about?

    We (the welders at work) have a hard time welding 60/30 NiCu pipe. It is anywhere from 6" to 18" and aboot 1/2" wall. All of the welding has to be done with Tig so it really is time consuming and then the Xray fails them every time:doah:. The first time I ever looked at a film from one of their welds I could clearly see a line where there was no fusing of the materials.

    That is why we have shipyards to do that for us:D.

    X-ray is tough, we have a job in the shop right now that is X-ray. It's 2.5" thick T-1 plate and the weld in question is a 3" diameter lug that goes through the plate. Mid-line root, back gouge the other side and then fill/cap both sides. The procedure calls for 11018 stick. We've done this job once before and I welded it up...and it passed the first time. We have another guy doing it this time and I don't have my hopes up too much.

    I find with X-ray stuff it's important to grind out the slight wagon tracks between passes...if your plan is to try and burn them out you invaraibly end of with LOF and a fail.

    Sorry to hear you guys will be on attempt number 7. :doah: :doah: I feel your pain!

    Yeah, prep is the key to making any weld good. This bugger is snake bit. We are filling it up to get after it again now.

    No, we have no problem x ray'ing them, pole smoker, it's keeping the garbage out of the weld that seems to be the issue. With your limp wrists, i doubt you could even hold a stinger let alone strike an arc.:D

    I don't even know what you are laughin' at Nancy (aka Dale), you wouldn't know a good weld if it bit you on the a$$:D :haha:

    So what seems to be the problem? What are you getting a lot of porosity's or what? I was certified in 1990 and did x-ray for about 3 years.

    I worked for Napa Pipe Corp. from 89-93. I worked my way up to visual and x-ray inspector. It was a lot of fun and I made good money for a young guy at the time. I was about to get into UT until the wonderful management of the company decided to turn the outfit in the wrong direction for the worse. I never got to do field inspection it was all at the plant. If things had not gone sour I would have been there to this day, one job I really enjoyed doing.
