gas welding using the oxygen acetylene process.using a small torch somthing like a BOC 'O' model.running pressures at:
Acetylene.7BAR
Oxygen:0.7BAR
You can use a peace of off cut lead as filler rod if in need.
Also lead does give off fumes and if you handle it to much you may get lead poisening and its also carsnogenic.

Hi Mcfearn,

Thanks alot for your help!
Infact, i am considering to use Tig process for this job!

It will weld without filler materials! I will use parent materials as the filler materials!

So, to do it, i should be rabbeting 02 work pieces!

How is your opinion in my opinion? Is it ok or not?

Hmmmmmmmm TIG welding lead!! Can't say I have ever heard of lead fused together via TIG process. What tungsten does one use? Gas? AC or DC?

I need to try a fusion run when I return to work, purely out of curiosity! But I cant imagine it welding successfully, but hey who knows?

Good luck and. let us know how you get on please.

I'd be a bit worried that TIG would boil the lead, giving off very dangerous fumes.

I actually did a proper search out of curiosity, appears lead can be tig welded using micro tig machines. Also it appears to be an auto process, I reckon this will due to the nasty fume lead gives off!!

I'd be wanting pure air system bucket setup attempting this free hand

I would use a big soldering iron
