Hi All,

I need to make up a fairly complex shaped lead flashing to go around a
pipe tomorrow. I fancy having a go at soldering the seams. I saw a
programme on TV a couple of years ago when this was being done using a
narrow strip of lead offcut as the solder but can't remember if any flux
was used.

Is it necessary and if so what should I use? I have some Baker's Fluid
and ordinary core solder as used in electronic work.

Thanks In advance

Bob

The correct way to work lead flashing is by welding using oxyacetylene. No
flux is used.
Cut a 10mm strip of lead to use as a filler rod. Remove the oxide from both
surfaces using a paint scraper. For a butt joint, make sure that the
surfaces join snugly. Mark a 6mm strip each side of the joint on the upper
surface and shave the oxide off these. Then weld.
Lap joints, mark a 6mm strip either side of the visible join and clean off
oxide, and also 6mm strips on the mating surfaces and clean. Then weld.
