Welding around threads - Pirate4x4.Com : 4x4 and Off-Road Forum

This is probably very n00bish but I've always had bad experiences welding threaded things (nuts, weld in bungs). Whats the proper procedure? Figure I could start my skills out from scratch

Spray threads with nozzle spray.

for nuts i insert a bolt it gives me a way to hold the nut and helps keep junk out of the threads.

anti spatter spray, and I will run a die down them if I need to when finished

X2, BUT, do not tighten. If you put any torque on it, it seems to warp the threads pretty bed when they heat up.

Plus anti spatter to keep dingle berries off the threads.

And there's no reason to get carried away. Two quick tack welds on high heat seem to do the trick just fine.

Brass shear bolts work nice

mudrebel360 · 04-22-2007, 07:01 PM

tig weld them

anti-spatter/ nozzle spray, have a bolt in the threads if it is a female or a nut on the threads if it is a male, make sure ALL plating is removed from near the weld area chase the threads with a tap or die after welding to clean up.

As stated above a brass bolt works wonders for holding a nut in place while welding. Also those cheap foam earplugs work great for plugging small holes while welding, grinding, and painting. If it melts while welding just run a tap through the hole.

A note: if you get weld spatter in the nut try to knock the booger out with a punch first, normally the booger will seriously tear up a tap.

To be honest I just drive to the grocery store and buy a can of pam and is pretty cheap, works just as good as anti-spatter

x2

I welded up 4 adjustable legs for my table and just snugged the nuts with some bolts to center the nut on the hole and had no issue with spatter.

If you just need to protect threads in a piece you're welding, then I use earplugs. They get a lil crispy if you weld right next to em, but punch em out with a scribe and the threads will be just fine.

generalee7 · 04-26-2007, 09:34 AM

Thanks guys. If you put the bolt in and tack weld the nuts, you wait til the nut is cooled down to remove the bolt, right?

I usually try to keep the bolt moving during cooling. I've had beter experiences with it that way. It seems to keep the bolt from sticking. And like said before: don't tighten the bolts that will warp the threads. And if it has to look good, use a TIG.

For good measure I usually use a bolt with copper (hi-temp) anti-
seize on it.

ear plugs are yore friends alwayse use them for plugging nuts. Plus they are free from my work.
