Weld repairing a Quenched and Tempered cast steel

[theedudenator]

I have a steel casting that is quenched and tempered and then machined

Weld repairs were performed after the machining.

I am assuming the casting should be re-heat treated.
Is it typical to just re-temper? or a full Q&T?

Is there a time frame to complete this after the welding is performed?

Are there any specs or standards I should be looking at?

Any specific tests/analysis to check the welds?

tc7 please refer ASTM A148 which defines minor and major weld repairs . Based on this 25% wall thickness is recommended.
