Mystery Rods

[itstippy]

I received a milk crate full of arc welding rods from an estate. Included is an unopened bundle of blue flux coated rods that are not for arc welding and have no identifying marks. I'm guessing they're for oxy acetylene welding, or brazing maybe? I've never done either so am unfamiliar with materials involved. Does anyone recognize these rods and can tell me what they are and what they're used for so I can label them properly? They do not make any spark when held against a grinder, they're too heavy for aluminum, there is no sign of oxydation on the ends, they are non-magnetic, and the metal is shiney silver. Nickel maybe?

Maybe Lagrange 70 rod?? Farm auction perhaps?

He had an excavator; I got a bunch of hard facing sticks he probably used on the buckets, Stoody Micromang and 2134s. I also got a lot of typical stick welding rods. All of that stuff I have ready use for.

Then there's this pack of long, skinny blue rods that I don't know what they are used for. They do not have a bare end for clamping in a stinger; the blue flux goes end-to-end. The metal inside the flux is non-ferrous and shiney.

My guess is nickel-silver brazing rods.

Blue coated, with a gold-end is classic low fuming bronze brazing rod for use with oxyacet heat.

I'd try one and see if it works, 16ga sheetmetal is about right, it should "wet" the steel like solder around an orange heat if I was close on my guess. Also useful for cast iron repairs.

I have some like that. It's Eutectic 16XFC nickel-bronze with a little silver. The XFC is the Xuper flux which is blue

It's used for brazing and bronze welding. It makes good fillet joints.

Thats typical oxy brazing rods. They dont spark because they usualy have alot of brass in them. I bet the flux drips off before the rod melts.
