摘　　要：异种钢对接焊在火电厂广泛应用,介绍了一种基于光声效应的激光超声检测技术在异种钢对接焊缝检测方面的应用,通过实验室与射线检测、超声相控阵检测方法的结果对比,总结该技术在异种钢焊缝检测方面的优点和局限性,同时为激光超声应用于异种钢对接焊缝无损检测提供实验依据和思路。Dissimilar steel butt welding is widely used in thermal power plants.Description is made on the application of a laser ultrasonic testing technology based upon photoacoustic effect in the detection of dissimilar steel butt welds.The advantages and limitations of this technology in the detection of dissimilar steel welds are found out by comparison of the results of laboratory,radiographic testing and ultrasonic phased array testing methods,which offers an experimental basis and idea for the application of laser ultrasound in the non-destructive testing of dissimilar steel butt welds.
