摘　　要：为了有效地监控T型贴角焊缝的内部质量,通过理论分析和可靠性试验,验证了T型贴角焊缝进行超声波探伤的可行性,确定了T型贴角焊缝超声波探伤的探头角度,设计制作了探头移动范围曲线(A-R)和闸门宽度范围曲线(A-S),使缺陷的判断简单化,并制订了该类焊缝的探伤工艺和缺陷的评定标准。In order to control the internal quality of T-joint fillet weld effectively, the feasibility of ultrasonic testing method for T-joint fillet weld was verified through theoretical analysis and reliability experiments. Suitable probe angle was chosen. For judging defect simply, the A-R and A-S curves were designed and drawn. And testing technique and criteria for evaluation of defect were written.
