Planning to make a helve hammer and will use FE connecting rods

[FERoadster]

Some of the helve hammers I've seen have a connecting rod to the upper arm so I'm planning to use 2 FE D2TE long rods and for strength want to weld them together side by side so the rods should be quite a but stronger. I think FE rods are forged so welding should be strong enough.
What welding rod would you recommend? I've been arc welding since I was 12 so technique won't  be an issue. Just wondering which rod. 6011, 6013 or 7014?
My rotating crankshaft will be a 360 crank shortened to just 2 main bearing mounts and the flywheel flange or the front snout for the pulley.

ESAB 48.00 is what i would use here in sweden dont know if
you have them in USA

[FERoadster]

Couldn't  find an equivalent in a search for the welding stick grade.
Our standards have the first 2 digits the tensile  strength and the 2nd two  the penetration  and polarity.
What does ESAB 48,00 relate to? I could only get to their marketing site.

Thanks and more research needed.

7014. I would prefer 7018, but you probably don't use that due to the storage issues.

Tried to remember what it stands for but 20 years and two strokes since i worked as
a welder so. But its a DC stick, we used it for most welding from ordinary construction
steel to steam boiler tubes, But if you are going to use two rods side by side, and i got
what a helve hammer is there would be no tension on the weld and i realy dont see why weld
them together since the tension would be along the rods and not sideways

[falcongeorge]

The issue with the weld wont be tensile strength, the issue is the welds ductility, or ability to resist cracking, due to the repeated shock loadings. I am suggesting a 70-- series rod because I know the  weld with 7018 in particular, is more ductile, and will not crack as readily as a weld made with 6011 or 6013.

7018 would be my choice, I use it even for cast iron. But in reality about any rod would work for your purpose.

It's cast steel not iron so welding it won't be problem will it crack afterwards time will tell.
I would preheat the rods before welding in a Owen or a grill then weld them then back to Owen and bring the heat slowly down.

Modern trend on these kind of welds is to weld in short stages so don't bring the heat to the piece but that's more for the cast iron.

I'm no professional welder so these are worth what they are.

Heo there is a saying here that real welder can weld a fish sticks to bottom of a boat with esab ok48

And Richard self made metal shaping tools are cool

[Heo]

Mikko, We have the same saying around here, I have worked a lot
with Finnish guys as a welder so maybe were i heard it first
48s are exelent on cast steel
