JPH,
My teacher, Buster Grubbs, one of the founders of the Ocmulgee Blacksmith Guild who has been smithing for, uhhh, 20 years or there 'bouts says mild steel wrapped hawks should be arc welded after forge welding because you can't trust a weld in mild steel. He said he had some sent back to him a long time ago, and now, just to make sure, he arc welds a spot in front of the eye.
