HIVEMIND HELP ME! Repair of metal colander

[u/je9183]

This colander's base has broken after many years of use. It was spot welded on in the factory. Do you think it may be possible to use a flux core or stick welder to repair it by just tapping it? I am aware that the metal is really thin and may burn through if you do it for too long.

The other alternative I was thinking was to drill it and rivet it.

Let me know your suggestions for welding, riveting, or an alternative.
