Galvanize weld connection
Galvanize weld connection
(OP)
I have L4x4X1/2" galvanize angle irons with nelson studds staggerd into them. now am faced with cutting off the studds a nd putting them into the center of the angle irons. i am faced with galvanize angle irons that have to be rewelded into the center of the L4x4x1/2". what recommendations do you have for me?

I'm assuming you can't shoot the studs into the angle and that you'll be fillet-welding them instead. Check with the electrode manufacturer to see if they recommend its use for welding through galvanizing, or if you need to grind off the zinc. Is this a D1.1 structural welding application? See the "Welding galvanized carbon steel thread" at Thread178-98196 .
Also, AWS has a publication called "Welding Zinc-Coated Steels". I don't have a copy so I can't tell you what's in it, but there's probably something useful there. See http://www.aws.org/cgi-bin/shop/flyall.html?mv_arg=WZC (or look in the "Base Metal Weldability" section of their online catalog).
