Welding Tips and Tricks

My buddy gave me a 10 pound bag of this filler . I read it's for power plants, petrochemical pipe, Inconel and welding dissimilar metals . Can I use this on mild steel ? What else could I use this for ? I won't be in a reactor or chemical plant anytime soon ...Thanks

Looks like it's a good high Nickle rod. Think it's used for high temp or corrosive environments. Other than being more expensive it's probably a good rod.

You must have an awesome friend because that is typically a high-dollar rod. Who is the manufacturer of that Inconel625 rod? Also, what is the rod diameter? I might want to buy some off you.

Idk who makes it. Every single rod has a flag tag with 625, a lot number , AFM something .... it's .045
What can I use this rod for , other than it's intended purpose ? I welded some mild steel together and
it welded pretty nice ...weird kinda silver weld . Flows nice too .

That's silver color is from the high chrome content. It says it has a very high tensil strength. Think you can use it on almost anything. The paper work I saw for it said you could even use it for hard surfacing. Exe. You could use it to coat over a wear surface between to parts to make them last longer.

Like if you had to build up a worn spot on a pivot point or a skid plate. I once ran a series of beads in a overlapping x pattern inside of a pipe that they pumped concrete through it kept the concrete from rubbing through the pipe and swing joints so fast on a big boom truck.

Rocket,
What you have is ERNICRMO-3 or 625 Inconel rod. It can be used to weld dissimilar metals and it's used when ever possible to weld Inconel to itself. It's less prone to cracking than most other Inconel rods. It's not easy to make a nice weld with because it's not very fluid, meaning you have to move it where you want it. It looks dirty when you're done.

You can weld cast iron with it, but there's other better choices that have a higher Nickel content. I wouldn't choose it for wear resistance, but if something's taken a beating it might be a good choice. It doesn't work harden as far as I know.

We use it quite a bit in high temperature piping where it transitions from one metal to another.

Jody has at least one video where he talks about using it and other high Nickel rods.

By the way, that's a good friend, that's about a $210 gift.

We've been friends since our Army days ...amazing how both of us clowns have moved up to where we are now ...we've always had a "one hand washes the other" kind of friendship and we've always got our eyes open ...
Anyway, I just welded some mild steel with it. It seemed to weld very nice . So I can basically weld most steels with this rod ?

It will get diluted into the mild steel and flow a little better than it will with a stainless parent metal. Pretty expensive rod to weld mild steel with, but there's no harm in welding non critical stuff with it. Try it on some stainless, 316 or higher grade and you'll see it's sluggish nature rear it's ugly head. Good practice though.

Thanks much Len . So there's no harm, Ok ...but is there any benefit ? I have a few pounds of ER70 and ER80 that I've used on steel sheet, angle and box . I also read on Jody's website, he has a nickel filler he uses called hasteloy that has a similar ratio of Ni Cr Mo . Could I substitute this 625 in the kind of repairs he uses hasteloy ? Or is it totally different ?

I found this on weld.com , it came from one of the applications they say it's used...haha

Washington Alloy 625 is a nickel-chromium-molybdenum filler metal used for MIG, TIG, submerged arc and plasma arc welding on Inconel? alloys 601, 625 and 690 as well as Incoloy alloys 800, 825 and 800HT to themselves or to each other. Washington Alloy 625 is excellent for joining these Inconel and Incoloy alloys to dissimilar metal such as carbon steel, low alloy steel, ferritic and austenitic stainless steels. This filler metal produces weld deposits with excellent corrosion and oxidation resistance against phosphoric acids, organic acids and seawater. Good resistance against pitting and stress corrosion cracking in chloride containing environments. The weld deposits exhibit high strength and fatigue resistance over a broad range of temperatures ranging from cryogenic up to 1800oF.

Applications
Washington Alloy 625 is most commonly used in the chemical processing industry, pollution control equipment, marine equipment, nuclear reactor components, pump shafts. Also used in the aerospace industry for thrust reverser assemblies, fuel nozzles, after-burners and combustion systems.

I'm not looking to sell it , I might consider trading some of it for different rods that I don't have . And yeah he's a good friend from way back , big ugly mean dude ...and smart as heck, moved up pretty high in his field(not welding). Guy can figure anything out for ya...and he usually follows success with a loud "Not bad for a big dumb Po110<k"
...his words, not mine...haha

well let me know if you change your mind.

Inco 625 is one of the fillers I used when I was welding jet engine turbine airfoils and blades. I also used Inco 718 and L605. Inco 625 and L605 were the 2 materials that we used for our certification. L605 would flow nice and it was shiny and smooth when finished. Inco 625 would not flow as easily and it was dull and rough when finished.

Several years ago our weld specialist had to scrap a bunch of our weld wire because they had lost the certification papers that went with it. He gave most of it to me because he thought I might use it for something.

He just got me more of the 625 in 1/16 , and 10 pounds of 617 filler in 3/32 .
As mentioned earlier, i'm doing small fab and repairs for myself and buddies.
Mostly dirtbike stuff, ATV , motorcycles , machines, tools ...steel , SS and stainless to mild steel .
Any benefit or reason not to use this 617 rod ? I notice it has cobalt that the 625 does not .
I have plenty of er70 and 309 that I use, but this 617 and 625 cost me nothing .
I just welded dumper sides on a lumber delivery flat bed F450 dumper truck .
I tried the 625 on a few of the non critical stringer beads welding the 1/8" side plate to the 2"x3" side supports.
It doesn't weld bad at all , welds nice...has just a little mucky discoloration on face of the beads .

I'm a big fan of using the correct wire for the job. I wouldn't use these materials on steel. I would use the ER70S wire on steel and keep the Inco wire for jobs that require that material. The Inco wire might "work", but to me it's not correct. If I was paying you to do a weld job for me and I found out that you use a filler that was not correct I wouldn't be very happy about it and I probably wouldn't be back. This is just my opinion and it may not be correct.

Big Gear Head , reason i'm asking is that I've seen jody use nickel based filler and he says it's good on most kinds of steels.
Other posters and vids say it's good too . I'm trying to figure out what the advantages , or disadvantages are of this 617 filler I just got from the same buddy that gave me the 20 lbs of 625 . I don't think i'll ever weld Inconel , I don't do paid jobs , I do this for myself or friends because I enjoy welding and fixing things in general . Im a medical professional by day . Thanks .

The simple answer is to do a few welds typical of the welds you'd normally do, but with some scraps and cut-offs you don't mind beating the hell out of, cut and etch a few specimens of different positions, and see how you feel about the results. If it will take ten times the abuse you expect your normal welds to take, free rod is great rod.
