Motorcycle production in the 1950s

well, its many years sense I did any gas welding Andy, but I don't remember it sparking like that

but maybe I am wrong

The only process I know that chucks out a lot of sparks and debris is air arcing but I can't think of any reason in the World they'd be using air arc as part of a production line.

Well he did say he was an apprentice :whistle:

There's a very good reason why I ended up working on turbines and my ability as a welder didn't come into it :whistle:

Not the piston .... he is putting he studs in

You guy's are sharp!

Looking @ the tanks, guages & twin feed pipes & bearing in mind what welding systems were around in abundance in the 50's. I'd say OxyAcetelene....torch in right hand with steel filler rod in left hand.
The commercial B&W films then were quite slow by modern standards hence the spark trails from a few micro seconds exposure.
End of rod is also blurred indicating slow film.
They are wearing dark lenses.
These swing arms have been tacked up on a jig with these guys doing a full finishing weld.

Maybe I did remember something from my apprenticeship correctly

We had to learn all the different processes in the first year before deciding where we wanted to end up and that covered fitting, fabrication and machining but only the basics so both the apprentice and the employer knew where we'd be best suited.

If only I'd known then what I know now I'd never have walked in through those gates back in 1975.
