How to Weld Copper Ground Studs to Steel
Attaching copper to steel requires skill and the proper tools. Brazing is typically used instead of straight welding, as heat is the primary factor in producing a weld that will not cause the steel to become brittle. Silver metal filler is used to seal the two materials during the brazing process. The torch and tungsten from a TIG welder is used to produce heat for brazing. TIG welders can be rented or purchased from retail tool outlets. Does this Spark an idea?
Things You'll Need

1
Use the wire brush to break up any loose pieces of dirt and grime on the area that is being welded. Use a shop towel to wipe away any oil or moisture that may be present.
-
2
Place the copper studs in the positions where they are to be welded. Apply flux to the base of the studs and on the steel in the area that is to be welded.

3
Pre-place the silver filler by bending it into the shape of the copper studs and setting it at the base of each stud. Pre-placing the silver filler metal will save time and help ensure a better weld, as overheating with the torch must be avoided.
-
4
Put on the welding helmet and insulated gloves. Position yourself over the area to be welded. Turn on the torch and adjust it until you have a soft flame large enough to wrap around the copper stud.
-
5
Hold the torch to the base of the copper stud and begin the welding process. Apply steady heat until the silver filler metal begins to melt and form a bond. Use more silver filler if needed to fill in small recesses. Continue using steps 2 and 3 until all the copper studs are welded in place.

6
Clean the area of the weld with a soft stainless steel brush. Use a shop towel to clean any splatter that may have occurred.
