When using SMAW ("stick") welding, galvanized steel can be welded in the same manner as uncoated steel. ... The thicker the zinc coating, the more fumes are generated, and those fumes have to be able to escape easily into the atmosphere and not be forced through the liquid weld metal.
non ferrous
ferrous metals contain iron, non-ferrous metals do not.
Silver is non-ferrous. Ferrous is a term refering to the presence of iron, so silver can only be ferrous if it were a silver-iron alloy.
Any piping containing Iron, usually Cast Iron, Steel & Galvanized pipe.
Most codes do not allow Galvanized piping/fittings on gas piping. I have used galvanized pipe/fittings on exterior gas piping before in the state of Michigan but other states do not allows this. Check with your local code authorities.

Lead, plastic. various ferrous and non ferrous metals and glass piping
Depends on the water quality and what type of galvanized piping was used
Galvanized piping or painted depending on local codes and type of fuel (gas) NO drip legs where the piping is subject to freeze ups
What is the application as many times such as natural gas it is permissible as gas lines exposed to the elements have to be protected painted / insulated or galvanized piping vanized piping
Domestic or Heating?=If your asking about domestic the material would have to depend on the PH of the water supply. Copper tubing type "L" is generally used but it is subject to the velocity and the water temperature.==Galvanized piping is also used but it can be s problem where mineral deposits can form inside the piping and dielectric fittings should be used to prevent electrolytic action from occurring when mixing ferrous and non ferrous metals=
Yes. Use a threaded fitting, male or female as needed on the copper and screw the galvanized into it.You must use a dielectric fitting to connect copper to galvanized pipe. If you don't, a galvanic reaction will occur and the piping will corrode and leak. You can use a Dielectric Union or a Threaded Brass fitting to join the two types of piping together.UNIONS can leak the best answer would have been a dielectric nipple

Galvanization usually refers to a thin coating of zinc applied mechanically or (usually) electrolytically to steel or cast iron pipework, as a protective coating against rust. Iron and steel (an alloy of iron with carbon and other materials) are ferrous. Overall galvanized pipework is ferrous. The zinc coating is not. Similarly, any coating of paint or rubber doesn't alter the underlying ferrous nature of iron pipe.
