钢结构T型贴角焊缝的超声波探伤

Ultrasonic Testing of T-Joint Fillet Weld in Steel Construction

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。

Abstract: 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.
