What SMAW rod for 316SS to A36 structural?

What SMAW rod for 316SS to A36 structural?

(OP)
Guys what filler would you recommend for welding 316 to A36.  This is a horizontal position weld to be made in the field.  The part in question is a 316 beam bracket for a new pipe hanger, Power Piping Fig. 200, that I am fillet-welding to an existing A36 W10x_.  Should I use a SS rod or can we use something like 5P-Plus?

Thanks for your help!

Thanks!
Pete

RE: What SMAW rod for 316SS to A36 structural?

I would use an E309 or ER 309 ss filler metal.

RE: What SMAW rod for 316SS to A36 structural?

Use a 29.9 or a nickel base like Inconel 112 if you want to avoid any problems.

RE: What SMAW rod for 316SS to A36 structural?

Absolutely, do not use 5P+ - a sure invitation to weld cracking!

Guys thanks for the help - I'll get the rod spec to the welder.  Pete

Thanks!
