I have an issue with a client about attachments/stiffeners? We have a formed part that is made of 1/4" material. There are four (what I call stiffeners) that are made from 1/4" material, and are 1 1/4" wide, and 24" long. The four stiffeners are welded to the material with the 1/4" width on the material, and the 1 1/4" width perpendicular. They are evenly spaced as to add support for the formed part. The weld symbol on the drawing shows a continuous fillet weld down both sides (24"). We welded it solid down both sides down to the very ends. The client insists that this part is an attachment, and that we should have stopped the weld at least 1/8" from the end of the part, and he referred me to AWS D1.1 2.4.7.1. I could not find a definition for attachment in the standard welding terms and definitions AWS A3.0. Can anyone help with the term of attachment?
