I'm in need of putting together a weld procedure for welding stainless steel to carbon steel but can not find any guidance in AWSD1.1 to help me with this, can any of you?
Parent - - By RonG (****) Date 07-09-2010 19:38
Your a little shy on information Bryon. What grades of SS, what Carbon steel and what filler? Also it would not hurt to mention an application. With that info there are lots of qualified folks here that can help you.

ok ron i need your guidance.

I am lookin at ss inserts for the doors, roof, etc on these sa200's. So I can sell to customers. The inserts will need to have carbon steel tabs on them so to ease installation for my customers.....????????

kaye you weld stainless to carbon with stainless rod or wire piece of cake

HI Kay, 309L would be the filler of choice. Runs and looks good and top quality weld.

BTW Kay, would you happen to have a old/new F163 Crankshaft dampener pully laying around?

Agree 309 would be the filler of choice.  Only problem and its really just a technicality depending on your business, AWS D1.1 doesnt address stainless steels or welding of dissimilar metals as you've already seen.  So, depends if youre customer has any issues with that or not.  ASME IX would cover it all the way around but to qualify the WPS you'd need tensile and bends for a butt test, fillets are easier.

Correct me if I am wrong but doesn't D1.6 apply when joining SS to MS?

Not unless its changed since I was on that Committee (which is a real possibility!).  I believe D1.6 is stainless steels only.
Parent - - By jrw159 (*****) Date 07-11-2010 12:41
So in the event of qualifying a procedure for SS to MS what code would one use?

jrw159
Parent - - By jon20013 (*****) Date 07-11-2010 12:50
Well, I think I mentioned above ASME IX would be the more common one.

LOL, sorry I missed that. So if generally working to AWS D1.1 in structural applications and one needed to qualify a procedure for joining SS to MS or weathering steel this note would/could apply?

"Welding qualifications to ASME 9 are for use with the ASME boiler and pressure vessel code or the ASME pipework codes. For use with any other code or standard, agreement between all contracting parties should be obtained."

John, INCO makes a few fillers referred to as Transition filler for joining dissimilar metals but even generic versions are pretty pricey. 

Another advantage to the 309 and INCO is a in some instances you can forgo PWHT. It’s almost a must in the repair business when working on large expensive finished machined components that you don't want to stick in an oven.

An alternate to ASME IX and maybe more palatable to AWS would be AWS B2.1, which is being tailored almost exactly after ASME IX.  In my own thoughts, one day B2.1 may even supercede ASME IX only to be superceded yet again by one of the ISO Standards we're also working on in unification works.
Parent - - By KSellon (****) Date 07-15-2010 18:48
I do
Parent - - By RonG (****) Date 07-15-2010 20:44
OK .......? Any thing you do is fine by me.
Parent - By KSellon (****) Date 07-16-2010 22:42
I have what youre looking for ( f163)
Parent - - By Bryan Bidewell (*) Date 07-12-2010 13:17
The grades of the materials I am looking to weld are A564 or A693 with regards to the Stainless Steel to A527 50 Carbon Steel. In terms of the filler this is part of what i am looking for recommendations on?
Parent - By RonG (****) Date 07-12-2010 14:33
Bryon, the A693 (I think that was with drawn a few years ago) is Zink coated sheet metal best I can figure. I doubt you intend to PWHT. Not knowing the application.....My thoughts would be turn to
INCO A (ENiCrFe-2)(SAW),

INCO 182 (ENiCrFe-3)(SAW),

or INCO 82 (ENiCr-3)(GTAW). You don't need to buy INCO (pretty pricey) but like American filler metals brand works as well.

The SS you mention is a PH material, didn’t know if you were aware of that, you will loose that quality at the weld.

Again not knowing the application, I will just throw in that you can Butter the SS side with 630 before making the joint, just a thought.

Ladies and Gentlemen:
       AWS D1.6 is the American Welding Society "Stainless Steel Welding Code" says qualify on carbon steel to. Lincoln / 888-921-9353 said last time I called use there consumable but no guarantees. I am not familiar with A527 50. It is not listed the reference I have handy. 572 is. Engineering judgment from far away guessing is where I am not going. I hope this is helpful.
Sincerely
