Fuselage Welding

Re: Fuselage Welding

Well, the choice is easy for me. I have owned a Smith's torch for the last 30+ years and can't afford a TIG outfit. So, it's gas for me.

Re: Fuselage Welding

Stinson used electric arc welding way back then and had to do the oven bit.
We did an experimental ship here where they put the fuselage into an oven when it was done and it was an all aluminum riveted structure.
I don't think I pre heat , I merely bring all the surrounding tubes up to a temperature below the red that I am looking for, do the weld and then flame it all evenly ,then let it cool with NO drafts... DONE!
There are alot of ships out there done this way that are 70 years or better, even the correct popping a hole or holes into the interior of the cluster to allow inside oiling is an art .
Then if the tube is properly closed off, all oxygen is gone thus no rust in the sealed tube.

Re: Fuselage Welding

Hi Mark , I answered your direct e-mail , certified Taylorcraft repairs require Oxy-Acet . I It is up to your A&P and IA if he ( they) wants to deviate, when the weld fails and causes a death may be on the side of the deceased parties family . pre and post is correct. I always wonder why, just do it with the torch in the first place.

huh?

Re: Fuselage Welding

Yah Dave, that's one I'd like to hear the reasoning for as well....that and the reference to it being listed on the TC.... I'm still trying to figure that out... but not holding my breath.

Hi John,

All this is making my head hurt.

I am going to ignore this discussion from this point in time forward.

I am just going to follow Richard Finch and ac43.13. Finch is recognized welding expert and author. That carries more weight in my opinion.

I apologize for creating the monster debate on pre & post heat!

No apology needed Charlies, thanks for your input and advice.

The part that hurts my head is the anecdotal diversions and unsubstantiated claims.

Or maybe I am just having a bad day.

I'll follow the other Finch (Richard) and from what I hear you saying then it sounds like you and I are on the same page.

I have thirteen 337's for welding in 2009 and about 23 337's for 2010 all related to welding (getting ready for IA renewal).

So I have an interest in this type of information.

I have to do some work this week and perhaps afterward I can get a picture of the HAZ to show Tim and answer Tim's question.

Re: Fuselage Welding

Yah Dave, I've been following his advice for years.... seems to work for me. I think we're on the same page as Charles. Amazing what goes on sometimes. I'd still like to see a TC that says you have to gas weld, or the other reference made... ohwell, on with the show.
Charles, you shouldn't apologize for any debate, getting info out there is always a good thing, especially when you have the skills and experience to back it up! Thanks!

Re: Fuselage Welding

Hi Mr. Finch

If you want a monster debate try the one on "can you really get a T-Craft on the step" or "is a downwind turn any more dangerous than an upwind turn". You might try the "I want hyd. brakes on my t-craft" or you can really set fire to the place by stating" well, I've dealt with the factory and got good service" better run and hide.

I am impressed by your shop and how refined your work appears to be, glad that you are with us.

Wow, things have cooled off on this topic, Now how can I stir things up some more....hahahaha Tim

Re: Fuselage Welding

Friction stir welding. I want to use that on my fuselage

Re: Fuselage Welding

I have seen a few of those fail, we were tesing frictions stir welds at 6000 psi leakdown. Tim

Re: Fuselage Welding

"Friction stir welding"

Speaking of friction welding, anyone remember the Spin Welder kits Mattel put out? Probably in the mid 70s.

I loved them as a kid. They really worked pretty well.
