Another 10 years and you'll have it nailed

Interested to read this thread and the technique people are using for lead welding. I live in an old house which I had to have an area of flat roof done in lead- because of a quite complex shape and a skylight window, there was a lot of lead welding required. Having used Oxy Acetylene myself for umpteen years but never having tried lead welding, I made sure to watch the bloke who did all the welding work. He used a No 1 nozzle and a hard, slightly oxidising flame, the resulting welds looked really good with a regular but narrow "stack of pennies" look to them. But it doesn't sound like the same technique used by others on here -perhaps there's more than one right answer on this.

Plumber, from the word plombier. Plomb, French for lead. What would they know about lead then ? A friend of mine was a plumber and in those days they even used to do the leadwork on roofing jobs.

Actually it comes from the Latin Plumbum which means lead..

i have spent the last 22 years welding lead with oxy/acetylene,what do you think

Outstanding work mate...wish you were closer as i could find you plenty of clients with work like that(not that you would need them)

I have been following this thread.

So?

3mm lead. Weld spec?

Amps AC-DC? tungsten size? gas? Gas flow? Filler rod size?

I can guess most of the above!

But because I have never TIG welded lead, I cannot get my head around. If it would zap the heat away or hold it and drop away in failure puddles.




I know what a failure puddle is from learning to AC alloy casting welding and TIG brazing

I can't remember lead flashing spec of rolls, general application lead I reckon?

Amps: 10 to 15 max.

DC.

1.5mm Ceriated Tungsten.

Gas: 10lpm.

Rods: slithers cut from lead roll or scrap. Oxide scale removed on all materials by SS wire brush.

Arc up and go like billy whizz. Lead dont hang around to long if you dilly-dally, interesting to fuse together.
