Hi Oxweld,
Thinking of doing a workshop within next months? Jan-Feb?
.... Barring chain requirements ...

The earlier Yakovlev piston-engined airplanes had ti exhausts. Gas welded.
I spoke with a number of engineers familiar with the factory. They agreed that the flux was impossible to acquire - made for the companies making the parts.
I tried for 10 years. Gave up.
It's not that my production required it. I can use TIG like all the Western World.

Glad to see you on the forum here.

Years ago, I gas welded some steel lamp buckets together, after having the sections spun. 1914 Stearns "Tonneau" model (sleeve valve engine - was quite a success on the AACA Grand National show tour.)
Lamp bucket on left is welded, cleaned and ready for final surface finishing - welds disappear completely, both inside and out.

crystallographic,

Yes, I think sometime in jan-feb would work O.K. for me, snow permitting.

Confirmation that the flux existed is exciting, I'd love to attempt some Ti welds with custom flux. Have you looked at this patent: https://patents.google.com/patent/US20070125986A1/en

Might be a good starting point for those interested.

Your lamp bucket welds are very impressive! The unfinished weld looks very nice, almost a shame to blend it. I suppose I will have to make something and post it now as well!

Thanks for the welcome!

Dates for next workshop: Dec. 3,4,5.

Some patents need "more experimentation." Like this one you list here. Money and time for product development in short supply. Need proven product. Now.

Yes! Glad to have you here.

Man welding tank_sm.jpg

I have always liked this image - young man welding thick aluminum tanks (see filler wire diameter) ...
With a stack of them behind him....
But his reflection in the surface of the tank says so much about his welding method/approach .....

But, then again, it may be self-explanatory to most ...?

That's a very cool photograph, hard to tell which torch he is using, perhaps a W-1?

His reflection looks serious to me, he'd have to have been skilled to construct those tanks. I wonder what they were used for.

Happy Thanksgiving.

...His torch looks exactly like my W-1 ....
Reflection indicates procedure.
Order of tacks and order of welds give reflection quality.
Aircraft tank factory.
Very Happy Thanksgiving ....

Darn wish I’d known about the workshop. When’s the next one? Will the schedule be posted on the tm website?

Hi Scott,
Be great to have you. This one cancelled - notice was too short in mid-holidays.
Thinking Feb - 17,18,19 ...? (I have a damaged fusellage/tail to work on - Jan.
Been getting my "2024T3 skin-straightening toolkit" fine-tuned.)
