I've had some luck with easy-outs and more luck with the stubby screw extractors Sears sells.
Welding a nut on reminds me of back 40 years ago. I was working in a machine shop and at morning coffe break one Friday I was livid. I had spent the week on one part and in the last operation, I broke off an 0-80 tap.
Geno, the welder asked why I was so peed and I told him my sad tale
He told me, after break, to bring the part and the rest of the tap to the welding shop.
10 minuted later I showed up with the part and the tap. He went in a cabinet and came out with a helmet he kept in a wooden box and in a felt draw string bag, sat at the welding bench, fiddled with some settings and welded the tap back together. He clamped the part to the bench and handed me a tap key and a loupe. The sucker came right out!
