A tig weld would be much preferable.
Welding copper pipe to steel.
And do not weld with ecuni or ercuni on to steel or exceed about 10 iron in the weld.
I use the term silver brazing instead of silver solder because technically anything over 840 degress f is brazing.
Cut copper pipe just above the corroded connection using a tubing cutter.
Wrap threads on end of the steel pipe with teflon tape.
The heat required for this type of welding is approximately twice that required for steel of similar thickness.
Copper is a malleable metal used in a variety of functions including water transportation and ornamental decorations.
Https goo gl frdnss why would you weld copper pipes versus soldering copper pipes pizzawelder well p.
To offset this heat loss a tip one or two sizes larger than that required for steel is recommended.
So here is the video with a few tips on silver brazing copper to steel and brazing stainless steel bolts to some copper washers.
This was done using a tig welder with silicon bronze rod.
Copper welding is not hard.

Oxygen free copper will allow copper to retain the original bronze color after welding by preventing oxidation.
Now technically this would be classified as tig brazing because the stainless steel has a higher melting point then the silicon bronze filler rod.
Tighten first with pliers then with pipe wrench.
Copper has a high thermal conductivity.
Install the lower half of the dielectric union to steel pipe.
Use two pipe wrenches to loosen the old union.
A tig welder is used when welding copper to give the weld seam the best appearance and a leak free bond.
It is resistant to rust and bonds well with other metals.
I would like to know if it is possible to tig weld copper pipe fittings to 300 series stainless steel.
P deoxidized copper contains low amounts of oxygen but tends to have up to 0 05 phosphorus and 0 05 arsenic which can release fumes.
Two basic principles that must be observed in welding cu ni clad steel plate are.
Remove the old union from the steel pipe.
This alloy generally has less than 0 02 oxygen.
Never let the carbon steel weld penetrate the alloy cladding or alloy weld.
