Early holden fuel tanks fe fc fb ek

[Pahs59]

Does anyone know how they joined the top and bottom sections of the fuel tanks together, were they seam welded? Spot welded?

I believe it’s some sort of a rolling spot weld that seals the join. It’s impossible to get apart From my experience.

Thanks ken,I thought they may have been seam welded like you say two rollers doing a continuous weld...I’ll still put my two tanks that I thought I might have been able to make one good one up in the rafters...I can’t bring myself to throw them out

I'm no expert but maybe lead wiping or brazing could be an option.

It wasn’t so much the putting back together, but the getting the tank apart without cutting the seam off

I have two fc wagon tanks one has a good top and one a good bottom I was going to make one out of the two..maybe carefully unpick the good bits...oh well a rainy day job I’m thinking

Seems obvious to me. Just cut and grind away the dud section from either tank. It was common to use volumes of lead solder to fill pin holes in the tops of rusted tanks. plug weld the two good sections together and seal with lead as suggested.
