I worked for British Telecom from '82 onwards and was unusual in that
I could already wipe lead joints (from plumbing experience) at a time
when this was a disappearing skill in telecoms. We never referred to
it as lead welding though, and used propane not oxy-acetylene.
I can also "weld" lead, as used for roofing lead. However in the UK
this is always referred to as "lead burning". I've never heard of any
lead work being referred to as "welding", either sheet, pipe or
IMHE, you need the right torch - the BOC model 0, which is absolutely
tiny. You might do it with an old Firefly torch, but Saffires (as most
of use use) are just too big. Oxy-acetylene is essential too - if you
only have propane, you'd be better off trying for wiped joints, not
As to the techniques, I found an old building book on how to form
valleys and gulleys showed me what to do, and some practice from steel
welding experience was enough for the how-to.
Use clean lead and always patinate it afterwards. Trying to weld
repairs in old lead is no fun at all, especially in a polluted city.
