    What you have described...a room hardened against R.F. energy is a very specialized job. They are a bear to design and there is a MIL-SPEC or MIL-STD for most everything. In fact the only places that I have ever seen them is in military structures, though there may be other uses out there. Shielding for the room/building is pretty straight forward... it is a grounded metal box, no windows and special doors. However, anything to do with the plumbing or electrical systems is very very problematic. Those pipes and wires all act like antennas and are really the hardest parts to sort out. I personally expect that the method is already specified and the fellows asking you the question just have not read the plans/specs yet.

    Bulldog,

    You might want to play with a phosphorous bronze or silicon bronze filler with the mig to see what you get, but TIG is the best option.

    Thanks tackit,
    Your correct most if not all of this stuff is controlled by the government. This is just a question. I make all the precast concrete blocks for the job and the company that I supply to knows that I do alot of custom mold work and was wondering if I could do this kind of work. I thought that it was probably tigged but thought it would be kinda cool if you could mig somthing like copper and brass together. Anybody know?

    I may not be reading you post right but it sounds like certified work, I would think the job would fall under government regs and standards pertain to nuclear material and also specify what welding procedure would be used.

    Welding copper to brass

    Hi everyone,
    I was at a job meeting tonight and was asked if I could weld copper pipe to a brass plate. The pipe is for a sprinkler system in a nuclear vault. It would need to be R.F. proof. I would like to use my mig. I'm sure it can be tigged but would like to try to mig it. Any suggestions???
    Thanks Bulldog
Working...
