I cannot recall ever seeing any HSE guidelines for lead burning but I know Lead to be very very toxic and even the mention of it is currently sending the Risk Assesors barmy.
They are asking for affidavits stating that the arc welding consumables do not contain Lead or have been or ever likely to be in contact with Lead.
I have this book at home there is a chapter on lead welding http://www.amazon.co.uk/Plumbing-Steve-Muscroft/dp/0750666935
some nice diagrams in it of flame movement and loading points but it is only a chapter I have a read true it later to see how useful it really is
Hi , As i said I teach plumbing at a technical College. They say separate overalls, eye protection (clear ) and there is an extraction system. We teach H&S on Lead and its mainly wash hands after contact ,dont inhale fumes. No food or drink in workshop.
Thats it. I would imagine the H&S bods have been through it as the students are from 16
years old.
I must say I did expect a huge issue but thats all . I have worked at 4 other Colleges and 2 private training providers and they were all the same.
Have H&S paperwork if you want it.
Hi ,blowlamp is hot enough but is not suitable as flame is not controlable.
Some portable MAPP blowtorches claim to be suitable for Lead welding but I.ve never used one .
Hydrogen / oxygen or Acetylene /oxygen is the proven method .
The latter gives the easiest flame control.
Blowlamp could be used to Solder lead however.
hi there i have been reading all the replys .i use lead every day as its my job eye protection and a good mask is a must have,put it this way when you are welding lead and the gun gos pop all that molton lead you are welding pops up into yor face and gos into your eye its not nice i have see people have it done to them and now one has lost the eye site out of one eye. i will put up a picture of a basic lead hoper i made which i have welded once i have the camera working.
does any one know if it is posible to weld alloy useing Oxy/Acetylene bottles ,cheers
You can weld aluminium cast aluminium brass stainless steel and probably more if you p.m. wozzaaah he will give you a link to his E books there is one in their called the art of welding which will tell you everything you need to know
Hi people new here , found this conversation and thought I could add to it , i passed city and guild in oxy acetylene pipe welding 25 years ago and had never tryed lead burning , have a set of torches and nozzles and was asked to make a lead slate for a roof by a builder freind , at first i was too hot and the lead drops away but once you have the flame right and the speed its not so bad , practice makes perfect ! having said that I was asked to weld shut a lead coffin of all things but backed out saying " Im not confident enough to do it " The answer to your question Yes with the deceased inside !
Keep your torch shining bright !
Being a time served plumber I did do alot of lead burning years back, you need to get the flame just so if you can hear the flame it's wrong, trying to keep the sheet flat is hard as lead expands so much but if you can keep the lead flat on a timber bench it acts as a heat sink and keeps the pool more stable....Chris.
