Mate....stop the overkill for an old frame. I welded much worse than that and i'm not a great welder. Even if your tube seat at 1mm away from the original axe.....for a run around no problem at all. Easy to add a reinforcement outside that you weld (a tube inside would be perfect if possible), not pretty but you can still use the bike for few more years.
Now if you want an excuse to justify a new bike to your girlfriend / wife or yourself...that's another story, we've all been there ;-)
