Unitec S-165

I'm rooting through some old stuff

I came across some of pops welding rods - wrapped in newspaper 1989 or older = that's 25ish years old.

I've got flux coated braze, 6013, 7018, 7014, 308ss


Would you believe that the 7018 has the nicest flux coating - hard and intact.

The 7014 is soft and powdery - but I'll try to dry it out and see if it hardens, maybe try it on some non critical projects.
There is what I consider a lot of it.

The braze flux is completely gone maybe good with external flux


I've got one labelled
Unitec S-165 3/32"
I can't find any reference to what that is, some maintenance rod from an out of business firm ?
amperage, polarity, prep and usage ?


I can't find any info on this at all.

It is a maintenance type rod. Looks like the 1/16" electrode. I don't think Unitec is in business anymore. We used it for any dissimilar metal joining, stainless or even cast iron in a pinch, or it was great for getting broken bolts out. I would build the broken bolt up until it was above the surface then weld a washer to this and then a nut to the washer and then back out the broken bolt. Use bees wax on the whole thing to give it some lube so it comes out easier, better than anything else and no noxious fumes. This rod can take a lot of torque and has a very high tensile strength also. This is similar to the Eutectic rod 608 cgs (9598?). I don't have the info on it anymore but I imagine it has a high nickel content.
The 7018 and 7014 are what is know as "low hydrogen" electrodes and need to be kept dry. They may be able to be salvaged if you can reheat them to be sure any moisture picked up in the flux coating is driven off by the reheating process.
 
So if I treat the unitec like 309 or 312 stainless i'm good ?


Are you sure that 7014 is a low hydrogen rod ?
 
7014 is not a low hydrogen electrode. It's a rutile electrode similar usability to 7024. The difference between the 7024 and 7014 being the 7014 is suitable for all position welding. Hence the 70"1"4. The 1 indicates all position whereas the 2 indicates flat or horizontal only. The iron powder electrodes like higher than typical amperage that you'd use with other electrodes.

You are correct. My mistake, the 7018 is low hydrogen, not the 7014. I have not used 7014, and looking at it is recommended for downhand on light material (sheet metal). We only used 6013 for this purpose, or Gmaw. Thanks.

I even had to correct myself, it's 8:30 on New Year's Day, not exactly wearing my CWI hat lol. I personally don't care for 7014 and would much rather use 6013 as you suggest in that application.

Count- about the green rod, try a bead with it. If it's stainless it will have a straw color to it. A lot of stainless rod has a blackish looking flux. Honestly if it was me, I wouldn't weld anything critical with it. It's just like using mystery steel in knifemaking, you just don't know what it is. When dealing with welding I like to know exactly what I'm using, backed up by documents.

I am not into blades, which I guess this site is really all about. I came across the question re s-165 rod and thought I'd give the info for it since we used that rod quite often and it is not a very commonly known rod. I don't imagine they like members conversing unless it is about blade info as if it was an email account, so I'll be taking off, but nice talking to you and a Happy New Year to you also.

In general I agree

But when I have to pay $35 plus for a pound of stainless rod, it would be nice to use this stuff up for the non critical stuff.
 
Welder78,
Thanks for the info. A little chatting off topic is fine. If you wanted to send Kevin and email, left-click his username header and the window will have his email link and profile info link.
