Hello,
I am seeking advice on welding procedures on welding a pipe made from Outokumpu SMO 654 (high-molybdenum content austenitic stainless steel) to a ship's shell made from carbon steel grade AH36 (ASTM A131M), thickness 8mm.

Well, if you're going to use SMAW, then here's what Avesta which is now also part of Outokumpu recommends for electrodes:

http://www.avestawelding.com/3246.epibrw

Here's the Avesta Welding manual in .pdf format which is part of Outokumpu Stainless, so if you want to know more specifics including welding parameters, and cautions as well as specific info on filler metals, then all you need to do is to look it up in the table of contents and you're "in like flint!!!"

Page 113 in the book for information on SMAW, or MMA electrodes, and page 228 for GTAW, TIG wires for both similar as well as dissimilar applications such as yours...P16 (Chemical composition corresponds to Alloy 59 - ERNiCrMo-13)  is the grade of filler metal you're looking to use whether it be for SMAW , GMAW or GTAW :

ENJOY and HAPPY THANKSGIVING!!! :) :) :)

Respectfully,
Henry

I believe Bohler own Avesta wlding consumables not Outokompu

They are indeed owned presently by Bohler as of 2005, but the poster didn't ask the question of who owned Avesta... However, I stand corrected in that it has been taken over by BOHLER-UDDELHOLM since October of 2005...  This is from their "History" link:

"2005
BÖHLER-UDDEHOLM sets new records for sales, earnings and order intake. The acquisition of Edelstahlwerke Buderus AG (Germany) is concluded in late June, setting a key milestone for the growth course of the Group. At the end of October, the takeover of Avesta Welding AB (Sweden) is finalized. BÖHLER-UDDEHOLM successfully completes a capital increase at the beginning of June.

2006
BÖHLER-UDDEHOLM closes its third consecutive record year. The integration of the Buderus Edelstahl companies and Avesta Welding AB is completed. The Group increases capital expenditure significantly, constructs a production facility for welding consumables in Suzhou (China) and acquires Helmold, a producer of special cutting rules in the USA."

Inconel 625 is a  ERNiCrMo-3 as opposed to a ERNiCrMo-13 filler... So if you can find a filler that's close to the chemical composition of the P16 then use it as well especially for "Dissimilar" welding as is your specific application... Also, Inconel 625 has a small amount of Cu (Copper)which may be detrimental to the weld grain boundaries upon solidification when welding the 654 SMO to the carbon steel which is the application the poster described.

What's important as well is this: when the weld is NOT to be subsequently annealed, an overalloyed filler metal should be used... Because of the high corrosion resistance of 654 SMO, the degree of overalloying required is unusually high and so in comparison to Inconel 625 filler, there's not enough Mo for overalloying which is why P16, or a chemical composition equivalent is recommended instead for use on 654 SMO. It's all explained quite plainly and quite clearly in these two .pdf's as well as in the Avesta Welding Manual as well.

And to add to what I already posted stefano, here is another filler metal that Avesta recommends as well for SMO 654 ,and it's brand name by Avesta is P54... However, since doing a little more digging, I don't recommend it for you application since it has a small amount of Cu in it's chemical composition, and may just cause problems in the weld upon solidification, so I wouldn't recommend it for your application.

Also, here's another .pdf for you to upload from Avesta Welding which covers welding wire for processes such s: GTAW (TIG), GMAW (MIG) ans SAW otherwise known as submerged arc welding:

Here's another .pdf for Metso Materials Technologies version of SMO 654:

Here's their overall brochure and their homepage:

Note: if you click on the link ni the homepage named: "news and Info" you will be sent to their complete document library covering all of their filler metal offerings.

And finally, since this is your first post, I would like to "Weldcome" you stefano to "The World's Greatest Welding Forum!!!" :) :) :)

Stefano, all you need to do is to read this thread regarding nanjing's behavior in other forums such as the UK forum, and you will understand exactly what type of individual this person is like, and how his reputation for being obnoxious, combative, arrogant, totally unprofessional speaks for itself!!! ;)

http://www.aws.org/cgi-bin/mwf/topic_show.pl?pid=142148;hl=UK%20forum

I'm not going to apologize for his behavior since it is "Stu Pid*******" that needs to apologize (we looked him up and that's the only full name that registered unfortunately! ;) ) I will apologize for not being able to do more to convince you not to listen to this obviously unstable individual! :( The information I posted speaks for itself and comes from the REAL experts themselves as opposed to someone who trolls the forums to start fights with anyone he chooses, so you decide which advice you would rather choose from - I rest my case.

Respectfully,
Henry

Dear respectful Henry, you do not have to consider apologising for me, I tell it how it is. Whether you are not in the front-line in welding, spending all your time posting links to welding information that you do not understand or divulging a convicted paedophile when asked, I will speak out. I have been in the welding business a long time and have a good name and people trust me (and pay me very well for it!).
You screwed up on welder 5354's question and you were not even man enough to admit it. You went to the absolute ludicrous stage of sending me threatening e-mails "to come and sneak up behind me" in China. Henry? no I do not think so. Every post I comment on you jump on and as per usual you are wrong. Welding 654 to carbon steel and you recommend an extremely expensive consumable when you can use a dissimilar weld with 309. (Why somebody is welding 654SMO to a ships hull in the first place is worth a question on it's own!).

Stefano, if you want real advice come to the experts who do this for a living. Do not listen to "the want to be Welding Engineers".

Respectfully NKG.

[Ok guys that is enough, Henry this is exactly what I'm talking about in the other thread where I was trying to get the topic back on track for the OP and was blasted for meddling in the conversation between you and Inspector 3.2. Now, You and NKG have successfully done it again in this thread, the OP didn't ask for your opinions about each other, he asked a different question altogether, so let's leave the personal attacks and insults at the door.]-moderator

I would never even consider apologizing to you here or anywhere els for that matter!!! You need to stop your lousy attitude towards everyone els in here especially to actual AWS members in here as well!!! Btw, are you and AWS member??? If you are ,then you are representing the organization in the most unprofessional manner!!! You then twist your own harassing behavior towards me by posting theses lie!!! You need to grow some cojones and post more information regarding yourself instead of hiding behind your presently nonexistant profile information...

You need to start behaving like a gentleman instead of sending people who you have dispute with in here, some really dispicable e-mail messages which I have copied and pasted as well as made both Ross and John Wright aware of your actions!!! So don't try to twist the truth around and instead, cut yourself a huge piece - no better yet, take an entire Humble Pie and start changing the way you behave in here!!!

I am an Individual member of this American Welding Society are you??? If not, then learn to behave in here because I am going to bring this to the attention to both Ross and John's superiors so that they can do what they need to as far as you are concerned!!! Make no mistake about it! You will be made aware of to the appropriate channels!
That is all I'm going to say to you from now on, but if you think I'm bluffing, then you will be making a serious mistake with respect to any future participation in this forum - CAPECHE?? You want to continue with your utter blather in here, then do so knowing that your days in here will soon be numbered - PERIOD!

Hi Stefano, weld it using inconel 625, a real common consumable.
Parent - By Nanjing Date 11-28-2009 05:30
Stefano, don't pay attention to all the rubbish. 625 is ok, in fact manufacturer states you can even use 309 for dissimilar joint. 654 has typical copper content of 0.5% and 309 has max 0.75% compared to 625's 0.5%. Remember this is a dissimilar joint and you need not look for the corrosion resistance of the 654.
