 i Wonder......?
What is the weldability of lead? I know you can't use the SMAW or the GMAW process, but I wonder if you are able to use the GTAW process. I do also happen to know the dangers of the fumes that come off lead when brought up to extreme heat, but this only holds true if you get the piece hot enough for the material to vaporize. Maybe on a very low current. Does it weld on AC,DC+, or DC-?? Any answers? -Hillbilly

A guy I worked with last year was a lead burner, like walls for Xray rooms... He Used a hydrogen/oxy torch. |

All the lead burners I have meat used gas torches. Traditionally you could use honking big soldering coppers as well.

Could you use TIG to weld lead together? or would it vaporise the lead? Would it be too dangerous to try b/c of this? If so, couldn't you just use a welding helmet with a respirator on it??

What exactly is it that you are trying to do? or are you just curious? You can just use a torch, other than that I don't know. welder19

I made several lead lined (1/4 inch) containers for radioactive syringes for a technician to have at several area hospital, I cut the lead with a skill saw and used a router to rebate the corners and then just soldered the seams. A 4ft by 4 ft half sheet of lead is not light.

The tig IMHO would vaporize the lead and create a very serious health issues. Lead vaporizes at about 700F. Electric current flowing through high resistance air gap generates an intense arc with temperatures ranging from 6,000 to 10,000 °F. This can be related to any welder when it fires up an arc to weld. Hope this helps

Welder 19; I'm just curious. That's all. What's IMHO mean?????

Can it also mean in my honest opinion? Isn't lead poisonous when exposed to it?
