Cast Iron pot welding stitch repair 

i would have scrapped the pot & bought a new 1, but your effort to fix the thing was remarkable.

Question will it hold liquid or did you just do this to keep it together for lawn ornament purposes.?

you have to preheat the entire pot, not only a spot. Otherwise, this is similar to spot welding, there was a localized expansion. You can do no preaheat at all, with the right stick.

I just watched myself do the same rust flinging. Good times in a shitty dream..

JB Weld..?

What size and type rod are you using? Great video!

It doesn't take that much effort to prep the entire crack area a few mm either side of the crack, inside and out. Keeps further impurities out of the weld pool - less to burn away and more to fuse.

Never get cast iron cherry red that's too hot
