Hi
What is the standard to calculate track width required for the current flowing through the track. Is there a rule of thumb that people work by?
My application draws 10 amps AC. What size should i be expecting?

Putting thick lines of solder over the traces helps to increase their ampacity without taking up any more space on the board.
I think it was the lack of a suitable fuse that caused the meltdown more than the technique itself.Hi Hero999,
I'm afraid for good reason that your suggested method burries a great safety risk. I saw this technique used in a UPS. Caused by a malfunction close to a short the copper traces got so hot that the solder melted and flew through the enclosure. If it piles up high enough it will cause more trouble.
A better way is using stranded wire pretinned and solder it onto the copper trace.
Soldering tin has a resistance of five times copper resistance.
