Welding filler metal

What's a good filler metal to weld cast to stainless steel

electrode · Fri Jan 27, 2017 7:56 pm

What type stainless? Here is a video that shows something similar:

A nickel rod would be a good choice although expensive or 309, 312 stainless or maybe even 316.

Or super missileweld.

It is my understanding that Super Missle Rod (is a trade name) is actually 312 filler.

Yes, I found that out years after I was first introduced to super missileweld when I first used it for stick welding. I bought some tig filler (split 10 pounds) with a friend and then after that found out that it is possibly 312. I wonder if they didn't add something else to is or really pulled a fast one by naming it "Super Missileweld".

Anyhow, the OP will need to let us know what his situation is on his parts for better answering what to use. Low stress static parts or high stress needs to be safe stuff.

I would disagree. The chemical composition is sufficiently different, IMO.

That's interesting. I have heard that super missileweld was the same as 312 but this may prove it is not. I always wanted to know for sure and this looks like the answer I have been seeking. And there is your nickel for the cast end of it.

I thought the formula was proprietary and under wraps but this chart is a keeper.

Thanks!

Oscar, can you tell me where your chart came from? Below is what I found on the Harris website. From what I saw it seems their rod is only available as a stick electrode.

I am not Oscar (of course not), but it looks like he was using a spreadsheet. Look here and click on Resource Tab and then on the MSDS sheet PDF and I think that is a good source for the info and maybe where Oscar got it from. The tig version is called "3SMW" it looks like.

http://www.harrisproductsgroup.com/en/P ... /3SMW.aspx

edit: I guess that isn't where he got the info because that MSDS sheet doesn't confirm the following:
Titanium
Tantalum
Niobium

Oscar, where did you get that info and do you have a copy of the whole spreadsheet??

That's strange, the doc I found says it's a trade secret, your MSDS gives the values Oscar has and when I went back and looked at the MSDS for 3SMW it lists nickel as 7-13% See HERE and open the MSDS

Electrode, the MSDS sheet you found shows values for many SST wires, I went to the sheet they provide for just the 3SMW in the link I provided above.

Too many open pages, try this one under the SDS index go to Welding > maintaince and Repair > SMW

Here you go:

Harris Chart, Part I, Section 2, 2nd Line

I don't see where it says 7-13%?

Yeah, that one is goofy. I you look at the first two entries:

Iron 40 - 70%
Chromium (as Cr) 30 - 60%

That means if they have 70% Iron and 60% Chromium they have 130% and that is too much.

And the Niobium, titanium, and tantalum etc have "NE" for not established and your chart has some figures in there...

Well, I need to go outside and burn the brush pile that is 15 foot tall so I will check back later.

Don't use gasoline! You don''t wanna know how I know that

Pfffft... I dunno about you guys but I have a life, I'm gonna go build a fort out of my welders.. them I'm gonna label some more stuff.. then I'm gonna organize all my rods in chronological order.

Hopefully get it all done before my wife wakes up and makes me do real work....

.... and even a rookie knows you don't use gasoline on a brush pile. Wheres the fun in that. Time to break out the thermic lance kit you got on ebay cheap that time and light er up.

I never did get pics but I soaked a brush pile in gas on a perfectly still day...figured I'd let it soak for a little while, came back..poured a trail of gas, lit the match and the whole pile exploded because of the vapor...I had long hair until that day

I have used diesel fuel ever since that day. My kids got to see it

There was alcohol involved

Not sure where you're getting that. 3-SMW is the TIG filler rod.

I got the values for my chart from the MSDS that also lists other wire in the SS categories. Look closely.
