Lead Pipe Welding
(OP)
I am looking for an equipment or technology which can join the two lead pipes together without soldering them. It more likes the quality of "lead buring" Process. Someone has seen it was done by "Mig Welder". If anyone has any information, please let me know.

In the uk any builders merchant will stock and sell compression fittings to join lead pipe as used in domestic water or gas supply. Cheers DW

1.All of the oxides must be removed-everything brite and shiny. This includes the filler.
2.Use hydrogen and oxygen,large tip diameter and low pressures. Must have a soft flame.

Is anyone concerned about lead fumes? Any process that melts the lead is going to create some fumes, especially an arc source.

When we had a lot of lead lined tanks and vessels we always had a lead burner on site. The biggest torch I've seen him use was hooked to a "Prestolite Cylinder".
Check with some of the local phone companies as most always have an expert in connect lead pipes. I would check around the union hall as a retiree may have more experience.

It has been a great help. Ledon's experience confirmed our finding at this moment. We are still working on the details of the parts to make welding process easier. I wonder if ledon has more information so that I do not have to spend too much time to optimize our process.
Thanks for the help.

No special ventilation was used.
The oxy-hydrogen setup had a single thick, soft rubber hose about 6 feet long with the mixed gas in it. That was connected to a Y where the gases were mixed. The business end was a simple brass blowpipe which I believe had an on/off valve on it.
