Is 6013 rod still OK if its not good metal or is their a better rod for general repairs.
Grind out the rust until you get to good material. 6013 will cope with a little surface rust but its far from ideal.
Trying to weld a rusty surface is a disaster, the rods burn away and you don't get a weld at all.
For reference, there is nothing in rust that is weldable.

In reality, is the cost of a couple of grinding discs excessive? because by the time you've bodged the job and done it again it will have cost you more in time alone, than the cost of a couple of grinding discs and a few minutes cleaning.
Doesn't matter how much you grind it. Its still not good metal.
Its a temporary fix on the farm until a new one can be made.
Well in that case it’s a temp repair then usually the aim is just to get something to stick, be it a patch or a horrible snotty lump! Don’t think a change in rod will make it any better / easier but a change in process might, mig would be a little more forgiving but I understand if it’s in the middle of a field it might not be practical to drag a set out...
Pure rust is unweldable.
Some 6013 are more tolerant of a LITTLE rust than others.
There's no magic fix, like Rrobson says it'll just be something to get a snotty lump to stick the joints together for long enough to bail you out...
Its sorted now. I just seen youtube videos that something like a 6011 would burn into it better than a filler rod like 6013 and wondered would it be worth while getting some for future.
