1. the detection method of an auto truck beam, is characterized in that, comprising:

  • Auto truck beam is carried out tension test, and detect the yield strength of auto truck beam;

    If described yield strength detected judge that there is yield phenomenon in described auto truck beam, and detection of end;

    If can'"'"'t detect described yield strength, detect pulling strengrth and the extensibility of auto truck beam;

    If described pulling strengrth does not meet the first desired indicator and/or described extensibility does not meet the second desired indicator, judge that there is yield phenomenon in described auto truck beam, and detection of end;

    AndIf described pulling strengrth meets the first desired indicator and described extensibility meets described the second desired indicator, described auto truck beam is carried out chemical composition detection and metallographic structure detection.
