Welding spring perches

If I warp a 1/2” thick tube welding on a spring perch then I think I deserve an award.
Dont tempt me to try
Quite some time ago i saw a video of someone who mounted a dial indicator and measured the change at wheel hub while they welded to the tubes.
It was very measurable and deformation should be considered. I'd at least jack it up under the paerches and let the tires hang to try and minimize loaded deformation from welding.

If you're really worried, burn em in, then peen the welds to relieve the stress in them. I think that is overkill personally, but it's not my truck. I like Obijuan's idea, and it would help prevent the tube from curving a little.
I like to see some pre-heat when doing perches. Try to get the area to 200-250F, then burn it in. Don't quench, or artificially cool the area. Make sure to wrap the ends of the weld, that will help prevent any tearing from ever starting.

i'm very sorry to be a PIA, but the question hasn't been resolved satisfactorily;
Please allow me to reiterate the question:
Will welding a perch, continuosly until fully welded onto an axle tube, put things out of alignment?
If so, what can be done about it?

Not a PIA at all. This is something out of my usual wheel house so I'm learning and reading. Still on the fence about doing it myself.
There's also a bunch of us that have nothing better to do but talk about. So being a PITA was never a worry.
I wanna know how much out of tolerance it moves, and if there's a difference in it being clamped down or running it in too hot

Also, If it does warp, how bad does it have to be before it causes issues. I know I’ve welded a lot of stuff on axles over the last 30 yrs. and have never seen anything look bent or not align correctly. No wheel bearing or diff failures. I’m curious exactly how straight all the axle housings going down the road actually are.
This.
I have welded on over to 50 axle housings. With no long term issues. Would I try to do a 200mph speed run at Bonneville without having one checked? No. For everyday drivers it is not an issue. I have put 4 on a friends axle straightening machine, he builds trophy trucks and desert race cars, the worst one was out .007" from center to the end of the axle tube on one side. The other side was 0.002" out the opposite direction. He has checked new Ford housings (Ford guy) that were worse than that. We did not take the time to true it up. Still in that go left car today. None of the 4 had to be fixed.
Oem tolerances are pretty loose thats for sure.
Some of the potholes around here could bend an axle tube easy I bet..or at least feel like it bent after hitting it!..

Everyone on this site should go out a purchase a $700+ dollar tool. To use once or twice on the odds of causing a major failure of an axle housing.
You have better odds of tweaking one on the trail, than welding on perches.

This was brought in to the shop of one of our Blazerbash sponsors for repair. Pretty sure it wasn’t cut to fit or installed very close, so that compounded the effect. Using a bore alignment tool, it was determined the axle assembly was warped 3/16”
I didn’t get to mess with it much, but I figured the tubes likely have moved at the center section as more than the tubes warped. This axle has been removed from service
@Tnsejed and I had a long conversation about axle deflection and wear at one point. Determined it would need to be significant to remove from service

I'm about as pro as Charlie Brown, but my opinion on your question of welding spring perches on a truck tube being an issue is something not to be worried about at all. Burn -em in. Stitch welding not required. Trusses, yeah ok if you want, but watch the cold starts.
What'll really get you is bashing it over rocks and bending spindles etc...
I think this whole thing is alot like Covid. Everything is fine and running good until you check. Then you're ripping those axles out and trying to buy new housings. Then you look at your daily driver truck and shit, its bent from the factory. They must not know what they're doing! Pretty soon you're loading up all the axles everywhere into boxcars. While this is happening I'm underground-railroading my bent to the moon axle coming up with some way to say it identifies as straight.
