PROCESS FOR DETERMINING WELD QUALITY USING FLEXURAL CHARACTERISTICS |
| 摘要 |
A process for determining the quality of a laser weld-seam, whereby a welded plate and a geometrically equivalent non-welded plate are subjected to a physical impact to generate a natural vibration frequency. The natural vibration frequency of the welded plate and the non-welded plate is then measured with an accelerometer and compared. The uniformity of the weld is then determined by the similarity between the natural vibration frequency of the welded plate and the geometrically equivalent non-welded plate. |

1. A process for determining the quality of a laser weld-seam, comprising:
subjecting a welded plate and a geometrically equivalent non-welded plate to a physical impact to generate a natural vibration frequency; measuring the natural vibration frequency of the welded plate and the non-welded plate with an accelerometer; comparing the natural vibration frequency of the welded plate to the natural vibration frequency obtained from the geometrically equivalent non-welded plate; and determining the uniformity of the weld by the similarity between the natural vibration frequency of the welded plate and the geometrically equivalent non-welded plate. |
