As a pipe welder myself in plumbers local one nyc I have never been called on welding a fitting to fitting. My experenice is on new construction high rise's and municipal projects
The water main is a six inch ductile iron main . And as far as the bonding to the gas service if we install a steel service line then we install anode bags on it to prevent grounding eating away at the pipe also when a steel gas service is installed two things are done one is a die-electric...
I work in NYC I am a plumber and have allways seen the electrical service grounded to the water main. Now keep in mind I work in new construction high rise buildings I have gone to this new job and the electrical contractor will not give a reason why he has not bonded his service to the water...
First off do you know your procedure? Do you need a root pass? What about purge gas's? Argon or argon mix helium? You haven't listed any of this! First you can get a actual torch hanlde for your plasma cutter that adapts to a pipe beveler ESAB makes this! I would not go with a 37 1/2 degree...
As a plumber what i would do is first make sure the lead is cleaned to remove all surface oxides then take a copper cleaning brush and a hacksaw blade and slightly score the inside and outside of the pipe. Then dependding on the size of the pipe find a piece of copper tubing that would fit snug...

The material is to carbon steel pipes with a 309 GTAW root,hot pass and filler pass (6") pipe the 309-15 is for the cap. This is for disimiliar piping we test out on for powerhouse work.
I am looking for information about the difference between 309-15 and 309-16 stick wire. I have used the two wires on pipe welding in a 6G position and found that the 309-15 will run like a lo-hi rod but the 309-16 clumps up and drops out I am looking for a answer because most of the rod...
Thanks for the info I do seem to lay in a nicer root at a higher amp. As for purging the inside of the pipe as as I weld should it be the same as the torch? I do have a spacer and tape up the joint as I weld it up
I have recently certfied on S70 GTAW/SMAW carbon pipe. I have been practicing for the 309 tig wire on carbon steel I sometimes get a nice root on the inside but there are times I get sugar I have tried different settings on the purge on the torch with straight argon. I ussally set the torch on...
