Non-prequalified Welded Joint

Non-prequalified Welded Joint

Non-prequalified Welded Joint

(OP)
Once in a while, we encounter a welded joint that is not pre-qualified (or shown in the AISC 9th Edition pages 4-152 to 4-173). Does this mean that we must assume the capacity is zero? Is there a way to calculate the capacity of a non-prequalified weld?

If a pre-qualified weld shows a butt joint, does this mean that the same weld should not be used on a tee joint?

I thought that all unqualified welds had to be tested.  This is a ? for AWS.

These are connections for Owner built monorails. We are trying to rate them.

RE: Non-prequalified Welded Joint

Have you posted this on the Welding, Bonding & Fastener engineering forum?

I do agree with scottiesel that its a question for AWS.
