weld fill in for re-drill

[mikehaugen]

Well anyway now that the jobs all done?.there are still some details of this project that are interesting to me.

There are internal stresses that will be created, and thus lessened by heating the a larger area. Also I think it would weld better. Are you thinking of the internal stresses? In any case, unless this area is highly stressed (or flexed in usage) internal stresses won't matter.

And it's my understanding that mild steel is not capable of hardening or annealing either (just by heat) but I could be wrong. If it was a heat-treated (or heat-treatable) material it would be no fun drilling that wrong hole.

Does anybody have knowledge to share on this?

I'm certainly not a metallugist, but occasionally when I research different metals for projects there seem to be many heat-treatable metals that supposedly have good machining characteristics.

Yes of course but I'd be surprised if the project of this thread would be constructed of a heat treatable material left in an annealed condition. I suppose it could have been carburized, where the surface is hardened for wear-ability, and in that case might respond to quenching.

Interested in the discussion.
