If you use Argon/C02 gas with your 220v mig welder on 'real hot' setting, it should have worked just fine. I weld hardened steel 1-3/8" ball bearings to a grade 8 bolt for one of my shop solutions and none of them have failed yet. You can always pre-heat before welding to give it a little more depth.
