Is this what nickel rod looks like ?

Steve@Advance · Sep 29, 2018

I wonder if that's not forged steel.

Seems like a lot of strain for cast iron on a part like that.

It could be ? Wonder what they welded it with ?

I think nickel rod is silver color

it looks similar to this rod.

I used this rod for a special job on some gravel crushing equipment by request of the customer years ago. Burnt a lot of it as the job lasted 18 days .

What does it cost a pound ?

I would bet that is forged steel, do the grinder test and make sure.

el6147 · Sep 29, 2018

customer provided it for the job, I was told then what the cost was but can't recall what that was. (about twenty years ago) I recall that it was not cheap, burnt the flux off every rod used .

job required something close to a hundred pounds, eighteen 10 hour work days.was never so happy to finish.

was only available in 5lb tubes

That looks like nickle welding to me. It weathers to a gray color and will not rust.

It is expensive, best to go to your welding supply and ask. Ni-Rod is what I use. There are several formulations for welding cast iron and each have a high nickle content. Very important to preheat and weld while it's hot, then wrap it so it cools down slowly. Otherwise you're likely to crack next tot he weld.

That part pictured is probably cast steel. But looks like it was welded as cast iron. You can weld cast steel with your favorite carbon steel weld rod. For heavy sections preheat is also advised.

You can tell cast steel from cast iron using a grinder. Cast iron throws red sparks with no secondary bursts. Steel and cast steel the sparks explode away from the grinder. Find a scrap piece of cast iron like a brake drum or engine block and put the grinder to it. It really is a different spark than what you're used to with steel.

If the part pictured is cracked next to the nickle weld you need to repair it with nickle rod as well, even if it's steel.

My 642 was broken there too. I pulled the 'eye' out once. cut off the broken eye and welded a piece of 1" flat steel in it's place. Ground down to a deep Vee,made a root pass with 6011,ground out the slag. then laid in multiple passes of 7018 and used an air chipper between passes.Acctually built it up above the metal then ground it smooth. It is still holding 3 years later.I think that is a weak spot on those plows as most I've seen are broken there. BTW,that part is NLA (no longer available). The last published price was around 1700.00 dollars.

Wow ! I?m glad whoever welded this did a good job I think I will slow my hydraulics down a bit
