Excellent ! Tells me what I needed to know to make this a lasting
repair . Preheat to ~450-500° , weld with 7018 , and slow cooling looks
like the best way to get a solid weld with small chance of stress
cracking . BTW , at some point someone corrected that .65/.065 mistake .

Thanks !

Sorry, but I just can't keep it to myself. How old is the Bush Hog? How much more do you think it will survive? What was the original material?

As I see it you are replacing the original material with one that is about twice as strong. And you are making the part three times as thick.

So my guess is that your repair will last about 6 times as long as the original part. So say the Bush Hog is 7 years old, then your repair will probably last for 42 years or until about 2059.

But maybe worth doing it right so you know how to do it.
