welded threaded pins "to discharge capacitors"

[Kaji]

hi working in hygienic design environment I was suggested using "prisoners to weld"; doing an internet search I found that for prisoners to weld in reality they mean these threaded pins to weld, I asked if you also had experience in their use and especially that small male indicated in figure with diameter d2 and length l to what it serves?
to slightly lift the pin with that inclination of 3° to facilitate the welding and especially the use is recommended mainly on bearing structures such as tubular etc or even on simple sheets of thickness 2 or 3 mm?
thanks for any answers and advice

they are also called pins to shoot, at least in my company, because through a special equipment the insert is "dipped" going to merge the piolo d2 with the sheet below.
is often used on thin plates, and difficult to access or where it serves for aesthetic reasons that the fixing screw is not visible

Yes thank you was the site from which I took the attached image, I would use them just "split" on a sheet because I can not make a fixing with screw holes and given on the other side and to have an internal threaded hole I should have pressed a plate, weld it to hold on both sides inside the sheet with the passing holes in correspondence of the males.
or make holes on the sheet and then weld on the inside of blind dice (but I do not like).
seeing that you talk about "thin clams" in my case the plate is 3 mm thick, a pin to shoot m6 or m8 is proportional?

Absolutely.

Go easy!

I'm late but I'm making my modest contribution.
I use them in bizzeffe to fix pannellatures on stainless steel frames, in this way I do not have to drill the frame or weld plates on it (which in hygienic environment means to weld all the plate continuously).
are very comfortable to fix also canals, swallows to tie the cables.
I recommend you to make wide holes so as not to touch with the captive's head the hole e.g. m8 with 10 hole.
do not think of using them for structural purposes, do not have great resistance or where bumps are planned (e.g. fixing handles of transport of machinery).
they are well also on thin sheets instead of welding a standard prisoner on 1.5 mm sheet have the great advantage of marking the sheet on the opposite side, on stainless steel you will see instead the sign of the welding.
at the economic level their use to allow us to save a hallucinating amount of time, shooting a series of prisoners is a much faster operation to drill and to males.
other advantage is that the machine is of simple use, from us the electricians use it to fix canals and swallows, first for hygienic reasons not being able to drill the tubular had to call a carpenter (inside) to be soldered these components,
if you have others ask
