1. A method for evaluating a welded part, comprising:

  • sampling information about yield loads corresponding to welding degrees of a plurality of welded parts in their welding conditions;

    making a correspondence data including the welding degrees and the corresponding yield loads;

    searching a relationship between the welding degrees and the yield loads and determining a compressive load for inspection on the ground of the searched relationship;

    applying the determined compressive load for inspection on the welded part;

    measuring an amount of strain of the welded part when the determined compressive load is applied thereon; and

    evaluating the welding condition of the welded part by judging whether or not the measured amount of strain on measurement is included in a predetermined range.
