Default 1946 Piper PA-12 Super Cruiser Fuel Tank's

Hello
I am a welder by trade , used to work as a certified A/C welder for major
company , still do Alum . and 4130 A/C welding , a man brought a wing tank
to me from his Piper PA- 12 Super Cruiser today , he has a small leak around
one of the fittings , the tank has been soldered together , he says it's
Alum. but I am not convinced , the sheet metal is very thin and is non
magnetic , I scraped some of the solder material and it was soft like lead ,
the man called an older fellow A/C restorer and he thinks it's Alum , all
the fuel tanks that I have worked on were made from 5052 of whatever
Alum.and TIG welded , 1946 may pre date the Heli-Arc process , wonder if
someone can shed some light on this wing tank question.
Thanks
Phil

Ask this question over at www.SuperCub.Org and you probably can get the
definitive answer. Lots of J-5, PA-12, and PA-14 mechanics there.

Being no expert, I believe what you have is made from "Ternplate". That's as
far as my poor memory will take me. Perhaps a search for that name will
help, as there are many references available..

tern plate was a lead coated mild steel.
I have an auster made in 1951. the tank is soldered tern plate.
you should be able to guess the material from the weight.
the auster tank is quite heavy. soldered up solid rivets in the
construction should be a giveaway.

In those days, they welded aluminum with acetylene/oxygen, using a
reducing flame and special blue goggles. In recent years there has been
a resurgence of this technique.

I am not specifically familiar with the tanks on the Super Cruiser,
however.

I did a Google search on "gas welding aluminum" and came up with a lot
of hits.

Try  http://www.tinmantech.com/ 

He has a kit for aluminum soldering and recommends it for attaching fittings and bosses to fuel tanks.
