I recently got a piece of pipe. I believe it is copper nickel alloy. I am going to do a spark test to confirm material. Does copper nickel alloy pipe give off sparks and what color? What other test can I do to determine if it is copper nickel alloy?

Update did a spark test with grinder. No sparks, material removed easily. Not aluminum because it's too heavy. JD Brewer

Is it possible to use dual shield flux core for an open root pass? on a 3G open root 1” plate test with a 60-degree “v” groove. Using 1/16” flux core welding wire
I am taking a structural weld test for a company and this is what they told me before the test. I have not taken the test yet. I have done open root with MIG but not dual shield.
