Re: best way to weld together two 1/4" lead sheets?

on the other hand, lead may fuse with copper. Maybe aluminum will be
better. I would definitely experiment.

I would try to use a copper backing plate and a big soldering gun.



Yeah... I'm surprised nobody just suggested cleaning and fluxing the
lead, and fusion welding it with a big iron, or a very small torch
running a reducing flame.

That's what I would do, I cannot imagine why it would not work. Of
course, it should be done in a flat horizontal position, backing plate
on the bottom, lead on top.

Ig's right about having a heat-sink surface behind. You can always
weld from both sides, but having a melt-through would be unfortunate.
Make sure the surface of the lead is in intimate contact with the
heatsink all along the joint. You can re-form the container wall
after welding.

The backing plate would address melt-through nicely.

Fusion welding is always a bit trickier than soldering, but not all
that difficult.

Set yourself up some ticket tests first, and get some proficiency at
it before tackling the real job.

Lead is a nice material to work with, I cast a lot of it when I was a
kid (probably not too healthy)
