摘　　要：介绍了红外热超声技术的基本原理及其特点,用这种技术对一个碳纤维复合材料T形接头和一块埋有裂纹缺陷的有机玻璃板进行检测,检测出试件表面及亚表面的闭合裂纹缺陷;对两块不同焊接能量激光焊接钢板进行检测,并由实验结果对激光焊接能量和焊缝质量方面给出了分析比较。In this paper,it gives the introduction of uhrasonie infrared thermal wave testing principle,a juncture of carbon fiber composite and an organic glass plate with fatigue crack were tested, and the cracks on the surface or under the subsurface of the sample were found. Then two laser weld steel plates by different welding power were tested, and the results give some analysis in laser power and the quality of the weld seam.

关 键 词：红外热超声 无损检测 裂纹 激光焊缝
