Spot Welding Nuts

Does anyone out there have any expieriance welding (resistance welding?) nuts on to .083 sheet metal. Need to attatch 3600 5/16 nuts to some .083 mild steel Stampings. Once had heard about something called projection welding where special nuts were manufactured with protrusions to assist spot welding of them . Trying to find some info or at least a dirrection to go

Thanks in advance John Kish

You can get them in all sorts of configurations. The ones I've seen used most are square like an old fashioned stove bolt nut, have 4 projections that make the high resistance contact with the base metal, and have a protruding ring that centers the nut in the proper spot. See P/N WP2701 at Ohio Nut. For your 5/16" nuts the pilot hole would be 3/8". If the base metal is already drilled, you can use the no shoulder version but you need some sort of fixture to align the nut with the hole.

It does take a fairly decent sized spot welder. It's been a while so I'm not sure > Does anyone out there have any expieriance welding (resistance welding?)
