We are trying to stay with all prequalified joints, but this came up in discussions here at work:
We have a 3/8" thick shear tab that is square cut and laying at a 45* angle to the web. The design drawing calls for a BTC-P4 in the 45* groove(made by laying the plate over 45*) and adding a fillet weld to the other side. Problem is the land is zero and a prequalified BTC-P4 calls for a 1/8" land min. I guess I can use my -1/16" in the fitup so I'm half way there. (we are using FCAW and SMAW processes)
Can I get away with not furnishing the land and still be considered prequalified?
I feel we get a better joint by not having the land, but was looking for other opinions on this from the forum. I'm not sure why this question hasn't raised it's head in our shop before now, but anyway here it is.
