AWS D1.1 Test plate
AWS D1.1 Test plate
(OP)
I have a welder doing a test to AWS D1.1. Figure 4.21 the Root opening shows 1/4" is there a tolerance? Just like angle shows 45 degrees is there a tolerance on that also?
Thank you.
Thank you.

If you intend to qualify you own procedure then use whatever you wish as long as the procedure is acceptable after destructive and non destructive testing requirements.

Find the picture in D1.1 that looks most like the joint youre welding to......
Seriously....... That's his answer.
RE: AWS D1.1 Test plate
Interp D1-84-014(2) indirectly provides further "permission" to use qualified or prequalified WPS's for qualification, upon which your joint details would be specified.
Just another of many ways AWS code contradicts itself.

RE: AWS D1.1 Test plate
Tolerances given in D1.1 are for "As Detailed" or "As Fit Up".
These are not applicable to a test plate.

There are no provisions in Clause 4 that permits the welder to be qualified using a joint detail that differes from one of those depicted in Clause 4 with one exception. The exception is for a welder that welded the test plate used to qualify a WPS in accordance with Clause 4. The condition includes passing all the requisite NDT and destructive testing requirements.

Subject: Performance Qualification RT/Bend Requirements
Code Edition: D1.1-81
Code Provision: Subsections 5.26, 5.37
AWS Log: D1-84-014(4)
Inquiry: Why are not both radiographic testing and mechanical testing required for welder or welding
operator qualification in 5.26 and 5.37?
Response: In the Committee's opinion, either radiography or mechanical bend tests are acceptable for
determining the soundness of the weld.
How does that interpretation relate to the question in this post?
