Hillbillysmith Posted January 9, 2008 Share Posted January 9, 2008 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 Quote Link to comment Share on other sites More sharing options...
Steve Sells Posted January 9, 2008 Share Posted January 9, 2008 A guy I worked with last year was a lead burner, like walls for Xray rooms... He Used a hydrogen/oxy torch. Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted January 9, 2008 Share Posted January 9, 2008 All the lead burners I have meat used gas torches. Traditionally you could use honking big soldering coppers as well. Quote Link to comment Share on other sites More sharing options...
Hillbillysmith Posted January 27, 2008 Author Share Posted January 27, 2008 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?? Quote Link to comment Share on other sites More sharing options...
welder19 Posted January 28, 2008 Share Posted January 28, 2008 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 Quote Link to comment Share on other sites More sharing options...
irnsrgn Posted January 28, 2008 Share Posted January 28, 2008 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. Quote Link to comment Share on other sites More sharing options...
Ronnie Posted January 28, 2008 Share Posted January 28, 2008 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 Quote Link to comment Share on other sites More sharing options...
Hillbillysmith Posted January 30, 2008 Author Share Posted January 30, 2008 Welder 19; I'm just curious. That's all. What's IMHO mean????? :confused: Quote Link to comment Share on other sites More sharing options...
Blacksmith Jim Posted January 30, 2008 Share Posted January 30, 2008 What's IMHO mean????? :confused: In My Humble Opinion Quote Link to comment Share on other sites More sharing options...
John Martin Posted January 30, 2008 Share Posted January 30, 2008 Can it also mean in my honest opinion? Isn't lead poisonous when exposed to it? Quote Link to comment Share on other sites More sharing options...
Black Ink Posted January 31, 2008 Share Posted January 31, 2008 I used to inspect trash burners and I got minor lead poisoning.Let me just tell you that it is the worst feeling in the world.Always feel like you been up for 3 days scatter brained I stay away from lead every chance I get.If you have kids strip in the shed and wash your hands with cascade .

Hillbillysmith Posted January 31, 2008 Author Share Posted January 31, 2008 Lead, in my knowledge, is only dangerous when ingested or put in the blood stream somehow, or inhaled when heated to its vaporising temp. It is DEFINATLY dangerous when messed with by some one who has no clue what they are doing or someone who is careless in what they are doing.

ksb Posted February 14, 2008 Share Posted February 14, 2008 I was in the battery business for several years - poured many a post and strap -always used gas. Although we had an electric 'post burner' I never used. It had a ground strap and a 'burner' end that was somewhat pointed. These were attached to a transformer ( low v, high a ? ) that pulged into 110v. It worked like a 'resistance' soldering iron (like came with my 40 yr. old Forney welder) . The current through the lead heated it up to the melting point. Never did get any good with it but it did work. Ken Quote Link to comment Share on other sites More sharing options...
