Welding Procedures Specifications(WPS) for Beveled Tee-Joint

[mrmalcolm]

Depending on the strength needed, there are different types of tee joint welds that can be used. The main types of Tee-Joints are:
a)Plain Tee-Joint,
b)Single Beveled Tee-Joint,
c)Double Beveled Tee-Joint,
d)Single-J Tee Joint,
e)Double-J Tee Joint.
For Welding Procedures Specifications(WPS) of plain Tee-Joint, A qualified WPS based on test piece with fillet welds could be used to welding of plain Tee-Joint.
So, if I want to weld beveled Tee-Joint(Single Beveled Tee-Joint, Double Beveled Tee-Joint, Single-J Tee Joint, Double-J Tee Joint), what type of test piece should be prepared and what tests should be conducted?
Thank you.

What does the applicable fabrication specification say, either directly, or by reference to another welding procedure qualification standard?

Assuming you're working under ISO standards:
A beveled T-joint falls under butt welds (doesn't matter if it's full pen or partial pen, it's a butt weld).
For butt welds and in most cases, tensile, bend and impact testing is required. This means you'll have to perform a butt weld on plate, so you can provide the necessary test specimen. Usually for these kinds of joints, macro's are also recommended. This means you'll also have to do a pre-production weld test.

Make sure if you qualify fillet welds in a T-joint (one side a single layer, one side a multi layer), you take into account the double of the heat input if you're welding the first layer simultaneously. I try as much as possible to separate both tests (sl/ml), unless they are to be welded simultaneously in production as well.
