    Weldable Primer WPS

    Or, do I have to qualify the welder to be able to weld thru this weldable primer?

    Weldable Primer WPS

    My main issue is that I can't find where it says you either have to qualify a new procedure or not. One way or another, I'd like to know where it say this.

    Weldable Primer WPS

    If we are wanting to put a lite coat of weldable primer on the steel to prevent weathering, do we have to qualify a new WPS in order for this to be legal with AWS D1.1? The code seems to be fairly vague when it comes to this and does not say specifically no primer or how much is allowed, at...

    F436 Hardened Washers

    I am looking into possibly producing a mass amount of f436 hardened washers for a job coming up..6" plate washers with a 4" ID hole. From everything I can find they don't give me the yield strength of f436, mainly because this material is under compression, but I'm trying to see if I can find a...

    Hardening problem

    Metengr: I couldn't agree more with what you said, but the man with the money makes the rules and my boss wanted to go in a different direction. I don't agree with it but I figured i'd try to get the informtation I could about other routes to take. But thank you for your advice.

    Hardening problem

    The entire story now comes down to this...the hole patterns for this were drilled and now are being changed. So we are needing to plug all of the holes, 3" wide through 3" plate. Once these holes are plugged and fixed, a new pattern will be set down on these plates and some holes might be in the...

    Hardening problem

    We have a very large built up girders that had some large holes drilled into the flanges which are 3" plates, A572, Gr. 50 steel. The problem we are running into is that these holes that were drilled into the flanges were too big and revised to a smaller size. So now after fit up of the girder...

    a913 Gr. 65 Steel

    Looking to find some more information on a913 steel and what exactly is needed for its use in structural steel design. What I've come across so far is a lot of positive talk about cost cutting and it's ability to be welded without a preheating process. But being a quenched and tempered steel...

    Another Sub-Arc Girter question

    We are using a single wire SAW tractor with L-61, 5/32" wire, Lincolnweld 980 Flux to weld up some 1.5"-2" thick girters. We're using a double-bevel groove weld (TC-U5-S) but the customers want us to do this without backgouging, so this becomes a procedure we need to prequalify, correct?? Any...

    Sub Arc on Girters

    I am running into a problem and need some help. We are trying to use a single wire SAW tractor with L-61, 5/32" wire, Lincolnweld 980 Flux to weld up some 1.5"-2" thick girters. The settings we are running with now are roughly 34 volts, 700 amps, and about 16-18 inches a minute. We've ran a few...

    Unequal Fillet weld leg lengths

    Looking through the code I can't find where they directly talk about unequal leg lengths in fillet welds and I wanted to know if this was legal or not. As I take it as long as the smallest of the leg sizes meets the correct weld size everything is ok..am I right thinking this and where can I...

    High Temp. UT Inspection

    I have a quick question...does high temp UT inspection require a different or new certification that that of normal UT Inpsection? If anyone could assist me I would really appreciate it or even if someone could guide me in the right direction. Thank you

    Estimating weld passes

    I was wondering if anyone could help me with estimating the number of weld passes using a FCAW process and .052 wire. If there is a quick way to simply get a rough estimate that would be great. I know simply finding the overall area and dividing by the wire cross-section could be a possiblity...
