to manufacture an internally stiffened plate made from sheet steel
(OP)
Hello all,
I am trying to manufacture a ribbed plate that is reinforced inside with stiffeners. I can weld the stiffeners to one plate, but then I want to weld the other plate, and I can't access the reinforcement. The stiffeners have low thickness, like 2-3 mm. I´m attaching a picture of a FEM model done in ANSYS using shell elements. I want to add a plate to the bottom, similar to the one on the top, and know how can I weld the added plate to the reinforcement. Or is there any better way of manufacturing this??
regards,
Hugo

Also take a look at the 'decks' manufactured for Skylab, milled from solid metal, using something resembling a keyseat cutter to remove large triangular cavities from the middle of the billet, leaving behind somewhat smaller triangular openings in one face.

But I agree with furnace braze.

Thanks for all the replies.
To CompositePro:
I would like to know more about Furnace braze. Can you post a document about its fundaments, with schemes??
To Tmoose:
Yes, all the stiffeners are full-section
To MikeHalloran:
Can you post the link?? I can't find it on google

I agree with laser welding. The problem is that we can't really see the welding joints to do a good through-thickness welding. Any suggestions on making it more effective??

The problem is that if I cut the slots on the second plate, I will have many separated triangles, not only one part. Do you suggest cutting the 2nd plate in triangles and then weld the triangles by through-thickness laser welding??
thanks,
Hugo

So you are also going to weld a bunch of short rectangles to a few long rectangles to form the grill?

So you are also going to weld a bunch of short rectangles to a few long rectangles to form the homogenous ice cube tray grill? Either before attaching it to the sheet, or at the same time.

As others noted, thanks to the modern miracle of CNC water jet machines, it would be easy to design your skins and webs so that they are fully self-fixturing using tabs and slots. The webs could be cut with alternating slots half-way thru their width at each intersection, so they would be self-aligning and could be fillet welded. And the skins could have slots cut into them that mated with tabs on the webs that only slightly protruded into the slots. This would allow plug welding between the skins and webs. Much cheaper than furnace brazing.
