    Cold bend steel plate

    I'm working on an steel element for assembling a railing on footbridge. It's supposed to be a steel cold bent or welded module attached to concrete parapet by anchors. For the moment a corner at the post is presumed to be welded and locally stiffend by small rib. However I thought to cold bend...

    Feasibility of welding

    Sorry, just now I got what you mean. I realized that the weld is within the range of flange, so indeed shear stresses are low there. But in my opinion, welding with not full pen, for example 2-3 mm left for support, gives a local peak of shear stresses (blue in the figure below). However it is a...

    Feasibility of welding

    Yes, it is a part of steel box section (see the 1st post). Why you asked?

    Feasibility of welding

    Indeed, I need full penetration of the web to maintain full capacity of this section. But as you said, backing plates should solve it.

    Feasibility of welding

    So you mean that it is possible even with thickness 30 mm. And with this 2-3 mm left for support I will have full depth of penetration of web?

    Feasibility of welding

    There are two combinations of thickness: tf=30 mm + tw=20mm and tf=16mm + tw=15mm, where tf - thickness of flange tw - thickness of web

    Feasibility of welding

    Then what about two 1/2 V joints like below? Or is it absolutely unfeasible?

    Feasibility of welding

    I'm not too much experienced in welding but I have the following issue. There are two parts of steel flanges to be connected together with vertical web. But the access is only from outside. It is a part of this section. My question is if this is possible to weld this in this way?
