Welding threaded bungs?

[dezertbronco]

I am welding the threaded bungs for the rod ends into the end of my radius arms, and after I finished the rosette weld and tacked the end into place I had a hard time threading the rod end into place. It went but not as easily as before I started welding.
Could the heat be warping the bung that much?
I thought welding the bung with the rod end in place would be too much heat for the rod end.

you could always just thread a stud in while welding:

nice looking arms

Any time you weld around pipe it will shrink the hole and usually will need to have a tap ran through it when done. Nice job

Your supposed to grease up the threads, insert the hiem or a substitute stud and weld. let cool and remove. welding bungs 101.

Thanks everyone, those were just the kind of answers I was hoping for.

I would also only weld a little at a time and allow for cool down. They are pretty thin, you can both warp them and burn through. I ruined a bung and a tie rod end on my home made track bar that way. There are a couple articles here or on Pirate on how best to weld in bungs.

I have welded several in with no issues at all. Tacked then got after it full tilt. I did have to clean the threads of a couple weld splatters, other than that they screwed in by hand after they cooled.

One note, if you have not welded them up, have you thought about putting a bend in them to keep from having excessive tire rubbage? I made mine straight with full width axles and they rub.. ticks me off that I didn't think about that during the build.

that is a nice looking arm. nice work. how long did you make them and what size pipe did you use?

I was thinking of putting a bend in, but I am not increasing tire size and didn't really have a problem before so I just made them straight.

Thanks, they are 8in longer than stock, and made from 1.75in .120 wall DOM tubing.
I still have a lot of plating to do but its coming along.
