I would be more worried about your plan to cut, twist and re-weld a link. The twisting will work harden it and possibly induce small cracks.
What kind of chain do you have?
Good point but I wonder if really true about regalvanizing.
I would think the original chain would have t be hardened/annealed before hot dip galvanizing the first time...so I'm not sure a second time would have any affect beyond the first.
The melting point for steel is up over 2500 degrees and zinc is below 800.
Interesting...a quick check didn't reveal the answer but maybe someone has the background or link (no pun)....
