Best way to Connect two thin plates

Best way to Connect two thin plates

Best way to Connect two thin plates

(OP)
Hey,
I have to connect two, maybe three thin(2-3mm) aluminium plates. The parts to be connected are about 200x200mm.
The parts will be moved around quite a lot.
I don't have to be able to put them apart with any ease, but it would be nice.

Any suggestions? Thank you

Flat head screws.
Spot welding.
Plug welding.
Adhesive.
Rivets.
Braze/solder.

RE: Best way to Connect two thin plates

The connection technique will depend on the function of the joined parts, so more info is required... the best way to connect for what purpose?

What loads are involved?
Vertical or horizontal orientation of joined parts?
Is connection in shear?
Etc, etc, etc....

There is also the factor of what your people can do and what tools are on hand?

With the able to put them apart bolting might be your best bet.

RE: Best way to Connect two thin plates

In what configuration are they being connected too, stacked on each other, side by side, in an 'L' configuration side by side...

Your OP, while you tried to give some detail, is a bit like asking "how long is a piece of string of .063" diameter?".

FC2008,

   Screws and PEM nuts, perhaps?

They will be placed one on top of the other. On the three plates I will "hang" a 600 gram weight so it isn't much.
Thanks!

Hi,
adhesives?
I knew an entire machine made of Al sheet plates, all bonded one another, no screw, no rivet, no clamp, nothing, only adhesives. For maintenance, dismantling or whatsoever: a special solvent...
A bit extreme, but it gives the idea, huh? winky smile

RE: Best way to Connect two thin plates

cbrn,

   There are always the Scoth VHB structural tapes.  These are supposed to be quite strong, and when someone asks you what holds everything together, you can reply "Scotch tape".

   It is too bad this does not meet FC2008's requirements.

RE: Best way to Connect two thin plates

Why do you say the VHB tapes don't fit his requirements?  He didn't specifically mention anything about joint stiffness.  I've tinkered with the 3M VHB tapes in the past, very good stuff.

FC2008, why do the plates need to come apart?  If for storage, maybe you can consider welding piano hinges between the plates.

RE: Best way to Connect two thin plates

MadMango,

   VHB tapes do not meet FC2008's disassembly requirements.  There are lots of ways to make a joint stiff.

RE: Best way to Connect two thin plates

I have used Dual Lock and it worked well.  It is kind of like  industrial velcro.  I used the type 250 connected to type 400.    They say not to use type 400 with type 400 because it "may be too strong potentially causing part damage or creating ergonomic issues."   Attached is the data sheet from 3M.
