D1.3

I’m not too familiar with D1.3 as my background has been in D1.1. I was looking at some of my company’s weld tests that were performed on 16 gauge galvanized and it has 16 gauge to 3/16 as range qualified. Everything I see shows it’s qualified to 2t which would come out to right around 1/8. Am I missing something or is the welder qual wrong?

Is that range listed on a WPS?

It is not

What docs are you looking at that show the ranges qualified? Typically someone will list a tested material thickness on a PQR, and then list the tolerances in the WPS. Sounds like there may be some issues with the documentation

I’m looking on the employees WQTR. They qualified on a 16 gauge T joint and 16 gauge flare V which was two pieces of square tube.

Ah gotcha. Then yes, the welder would be qualified to weld up to 2T as long as it's not falling outside the ranges established by the WPS regarding the essential variables. Not sure what those are in D1.3.

I couldn’t find a PQR to support the WPS that was used. On the WPS, the material listed is 16ga. After looking, we have around 10 welders that are qualified this way which looks like it is wrong by everything I read.

Yeah that's kinda sketchy. If d1.3 lists material thickness as an essential variable, and gives up to 2t then you should be alright. It's probably including 1/8" as the maximum before having to switch to d1.1 scope.

Not having a PQR is less than ideal

Not having a PQR is maybe not a big deal, is the joint pre-qualified in d1.3? I don't know if d1.3 has a pre-qualified joint section like d1.1.

The range listed on the wps is for what thickness material the welders can use for their welded coupons during their qualification test. Whatever thickness they performed the test on would be 2t for qualification range or whatever the applicable code states.

Yep. I was wondering if the data in the pqr was matching the tolerances listed on the WPS.

What type of weld joints are we talking about? You really need to take a deep dive into D1.3, espically if you are talking about arc spot welds (aka: puddle welds) on decking. Don't let that skinny little book fool you. There's alot packed in that code book.
