We have to weld some tubular weathering steel members that will be AESS so I need to make sure the color match issue is addressed. My Lincoln guy said Ultracore 81Ni is the wire to use (FCAW) in shop.
I wonder if there are any plans to add ASTM A847 to the list of pre-qualified base materials. It looks the same as A588 but a different shape, tube instead of W- shapes and plates.
