Mitered Stringers

Mitered Stringers

(OP)
I am trying to determine the best weld call out for mitered stair stringers. What is typically called out for this type of weld assuming full pen?   

RE: Mitered Stringers

After conversations with several fabricators, I stopped specifying, I just put a single vee grove on the outside. They would change it to their preferred if they wanted, I checked what they provided on the detail drawing.

Timing has a lot to do with the outcome of a rain dance.

(OP)
I guess no matter what the weld has to be back-gouged for this situation, no?

RE: Mitered Stringers

Toad, it's either back-gouged or an unsightly back-up strip.

MITRE CUT & FULL STRENGTH BUTT WELD

RE: Mitered Stringers

Check you stresses. Do you need a complete joint penetration weld? If you do, the you will likely need to add stiffeners in the web to resolve the flange forces (since the "beam" has a knee in it and the flange forces don't cancel out).

Hopefully you don't need the full strength of the member. Even when I don't need the full strength in the weld I still spec it as a CJP single bevel. The shop can decide what is the best weld for them    

RE: Mitered Stringers

I used full strength because I wanted to seal the joint.

p.s. How does kikflip get a star for that post? LOL
