Welding A36 to 1018

By wrd Date 07-09-2005 00:09

I want to weld a CF 1018 bar to a A36 hot rolled plate. I'm using the 1018 as a boss and want to use the CF 1018 material because of tighter tolerances than hot rolled A36 round. Are there any weldability issues between hot rolled A36 and CF1018? Does anyone know where I could find more information on this?

The combination should weld beautifully just as if you were doing A-36 to A-36. No big deal.

How about welding an A307 or A325 nut to an A36 plate? Is there a reference that I can use to prove my position?
Thanks,
Jim

A307 and A325 are both unlisted materials so "technically" would require that a procedure qualification be written. They weld beautifully however to A36 using "plain jane" 70 series carbon steel filler metals.

What "position" is it that you want to prove?

Jim,

Your nut is probably ASTM A563, not A325. A325 is your high strength bolt. This too, is an unlisted material in D1.1.

I would like to prove that it works and somehow quantify how much weld is required to resist the load on the part.

The welding part of it will work beautifully but I have to remind you that you may need to qualify a welding procedure (depending on your industry and customer requirements). Can't comment regarding your load and the ability of the weld to resist the load.
