Default Flux for lead soldering

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.


The correct way to work lead flashing
is by welding using oxyacetylene.


"oxyacetylene"? Please?? An ordinary blow torch and ordinary solder and
flux will do at a push. Many used sticks of grade D solder and "wiped"
around the joint to tidy it up.

You can use no flux, as many did, by "lead burning". You need a directional
burner on the blow torch and know what you are doing, otherwise lots of
melted lead about.
