see my post ,
6881 has a much higher tensile strenth than 7018 or 6010. i would have gone 7018 personally as 6881 rods are ridiculous money, but 6881 will be more than adequate for this imo.
i was replying to different posts.
i was comparing to 6013 .
im sure the repair he has done will be fine, he looks a very good welder.

Me personally, I wouldnt have considered using dissimilar for welding the linkarm, as its no special steel(s) infact they will bend if you catch them hard enough (sideways, /a hard bang to the to the side ) ive done it before, they can be pressed out again, maybe not quite as good as new but....
it wont be made of high carbon steel ,
I wouldve used 7018, ( i like oerlikon supercitos spelling?) on my AC welder whatever ammps and set on 75 ocv.

All I can say is that in 50 years of farming, I've never had to do it. When I retired, I had a 34 year old Fiat 780 DT with 6500 hours on it. It was the main ploughing tractor for a long time. Lower link sensing too, so it took some punishment.
6500hrs in 34 years, 190 odd hours a year ?
The tractor belonging to that arm has clocked up 19800 hours of torture so far.

Never seen a massey arm bend, seen a couple break when the check chains gave way buckraking. They broke clean with no distortion or bending.

What process do you favour for cast exhaust manifolds?
If it's cast steel, then anything... probably MIG if it can be cleaned up properly. Or TIG, which is my preferred process since it's the one I'm best at.

If it's cast iron, then pure nickel cast iron MMA welding rods, lots of pre heat and slow cool down afterwards. I try my best to avoid cast iron though!

I suggest you take it off and weld on a new one. However, I don't insist on this as I'm just an amateur. Maybe ask the same question to a qualified welding specialist. I've been practicing for some time, and it really interests me, but I still don't cope with all the situations I encounter. I guess it's time to sign up for a welding training course and obtain a certification in this area. I was thinking about https://ratemywelder.com/welding-schools/ since they provide online courses, which save so much time. Did somebody here work with them?
That's a great idea, I've been sat here for this last 16 months looking at this wondering what to do with it and participating in an online course of a practical course is just the solution. (y)
