Here's what a welded 6061-T6 aluminum angle looks like. This came with my April 2012 fuselage kit for a longeron, and I don't need it. Since I'm building up the basic fuselage structure, I made a current inventory of the angles and found this.
What we're looking at is a weld that was made to make the angle longer.
When 6061-T6 is welded, it's never as strong as it was. Typically it's half or a little over the original strength. One of the aerospace companies I consulted for had a special proprietary welding process for 6061 that recovered almost 60% of the strength, and that was the best I've seen.
So keep your eyes open!
In this view, you can see that the added part isn't even straight.
And here's the other flange.
I sent these photos to Van's.
