Lead welding

[J.B. Welding]

I would never have dreamed of doing stuff like that or mixing agricultural and petrochemicals

That was my brothers department..

oh well you only live once ... bight as well go out on a bang

If you're going to be lead bashing in-house and, lead burning in-house too. Use TIG, DC e-, about 15 amp, 1mm tungsten. Same preparation required, except a wire brush is ok for removing oxides.

I always wondered if but never tried it

Tig money Versus oxy bottle money....Hmmmm

A little scratch start TIG MMA inverter you could strap around your shoulder with just one bottle? I am going to give it a go, the only issue might be shielding gasses but Gas welding lead aint easy in a stiff breeze either

When I was experimenting, was in ideal workshop conditions. Doing say a 45 degree welding up or down, was difficult, lead just fell away, where with O&A, was a little easier.

Down hand is ideal. Does take practice to iron out the various issues. If using say, a single phase inverter on-site, encapsulating work area may be difficult.

Lead Sheet Association use to run courses for tig welding lead, don't think this was too, successful?

Ps, remember your six month bloods, if working with lead on a regular basis!

played a bit with tig ing lead, ok on the flat... preferred oa,

I have just picked up this thread As Boc got to expensive i now use map gas with regulator and a small oxygen as map gas has acetylene in it you can weld steel tube It is like a small port-a- pack. I also use it for silver soldering brass fittings to copper pipe using std torches may be worth a look.

I used TIG and a turbo torch, TIG was OK but had to be very clean; the oxide forms on lead in front of your eyes.

I found using the turbo torch a SS brush, lead free solder and flux. Does the job very well

I assume you mean last line with tig? Prep exactly same if lead burning with O&A, slithers of same lead, wire brush oxide film, no flux required, as argon free's area of oxides, which was maybe I why missed oxide film formation.

 

[Shox Dr]

No. ended up using the turbo torch (MAPP)

 

[Rrunnach]

Ah OK, I understand, you soldered the lead.

 

[Shox Dr]

No not as such, the base lead work pooled you just had to push the lead free under the scum, worked a treat.

I have used above method, (no O/A) E- (I think, heat goes to work oxides lifted) also small nozzle using shield gas as sort of jet like flame force. This was on a workbench indoors with backing but with good results. On a roof in situ soft solder sticks underpinned where necessary / possible with sheet copper. Worked for me anyway.

Just re read and nearly choked on my yogurt. Can't work out how to edit so,, Replace "heat goes to work", with Heat goes to tungsten so I used a 2.4 on very low amps DC. It was late.

I am going to try the tig for one Leadpiece for the garage log burner. Even as a Slater I always got my leadpieces made up for soils etc.
You cannot beat a proper Leadpiece for going through a roof. Easily dressed and folded at sides and top for driven or running water.

 

[crazy roofman]

Been lead welding for years now. When there was a shortage of acetylene the bloke behind the counter told me to use propane with the normal nozzle I use and use a small hole punch on the nozzle to indent it.. I never tried it though..

 

[jonathan dempsey]

Here in Hastings we buy 9 litre bottles of oxy acetylene. The initial cost is high. But trying to weld neatly with propane is a bitch if not impossible. As to costs to the customer mentioned in previous comments. I have this to say. It costs what it costs. Want it done right then this is the price. Want it bodged, find someone else. I’ve been in this business quite a while and it took some learning but if you charge right, the customer will be happier knowing they paid for the proper job. You’ll win more jobs being correct than by todging it over.
