Welded? Yes. Well done? Not so much.

Happy Canada Day!

Meh..... The welds look like they'll hold & will work fine. How about well-done enough?

Considering I haven't touched a torch in weeks and still have very limited experience - I am pretty satisfied. I'll get better with time.

But, for now functional is perfectly fine.

It's going under the car, it'll be fine.

I commend you on a project most us mortals aren't equipped or have the skills to take on such a project. Imo you have a design flaw in your mufflers. Due to the amount of heat the inner muffler core will see vs the outside there will be different rates of expansion. In that style of muffler the inner core should float on either or both ends.

Thanks. That's a pretty fair point. And it would have been easily to account for a month ago. Where the hell was this advice then? 😉

Given the quality of the insulation there should be a very noticeable difference in temps between the inside and outside. Also the mufflers are quite far back in the system and the temperature drops off quite significantly post-cat.

I guess we'll see how long it lasts before failure. Good news is I can always build another set should the need arise.

I'm guessing you've already recorded finished weights for each unit?

The best part is I can literally look at them and go: first set of beads ever (4 weeks ago), second set of beads ever (2 weeks ago), third set of beads ever (yesterday). And there is a notable difference and improvement.

For people watching on the fringes: As a hobbiest there is nothing to be ashamed of, stay the hell off Instalies, and just do you.

I'll post some pictures later of the first ever MIG welds I made 20 years ago and the most recent.

Not yet - but was on my list of things to do.

I'm hopped up on meds and may be visualizing wrong.....

Isn't the inner pipe/core still visible/accessible from inside the pipe opening?

If so, couldn't a Dremel with a cutoff tool modify it being attached at both ends by curring from inside? Or am I just picturing the assembly wrong?

If I had thought it was going to be an issue I would have used a slip joint as an a means of managing the potential expansion issues.

But, here we are.
