As per title, using an arc welder, can I weld box section to a disc? If so, what rods should I use. Doesn’t need to be super strong, it’s just a base so the disc can sit above the ground horizontally. Cheers.

Should be fine with normal rods, I’ve done it with standard mig wire

Mig wire with argoshield gas is equivalent to 7018 rods

Don’t think so! Dissimilar rod would be best.

As an aside: I've heard or maybe read on here that the way to drill one is to put a decent sized nail in a pillar drill and give it some until the disc glows red. Let it cool naturally and it will be soft enough in that area to drill with a standard drill.

What do you mean when you say what mix?

I don't know somuch
Id prob try mig first
If it did owt nasty try dissimilar
But my logic would be that those two metals are dissimilar

What is the OP actually making? I’m presuming a fire dish or something of that ilk. If so just mig it, why complicate things?
312's at a guess.....

totaly agree if a stand for a bench grinder it may need to be a bit better but if worryed just use low hygen rods and heaps of heat will work

It’s a fire pit, got 10 to make. I don’t have a mig welder, just want to cheaply make a bases to keep the disks of the ground. In fact, I’ll probably just make square frames and just sit the the discs on them.

just crank your welder up a bit and GP rods would work ok for that
Triangular frames... 3 point location, no rocking.
613 's will do it.
... try some Bohler phoenix blau 30 rods ... bit extra money than common or garden ones but worth it ir.

Am I the only one here who would nave just welded it with the normal mig or standard general purpose rods without even giving it a thought???
All this different rod numbers, mixes, disimilar rods, making me feel a bit of an amateur!!!!
I own 5 welders and have been welding stuff for near 40 years and I am still learning but keep it simple guys ! !

Yes, ordinary rods when we found out the application.
But the first post led me to believe it was for a disc harrow that was going to be used again in anger and possibly for a customer. So I put the belt and braces on from the start ............
