Abstract

Weld inspection of stainless steel pipes and pressure vessels is one of the most challenging and difficult inspections for ultrasonic testing. This is due to variations in grain structure and associated anisotropy. Anisotropy causes grain scattering and adversely affects propagation of sound waves. The effect is more telling for shear waves, which, in many cases, have almost no ability to penetrate the weld volume. Longitudinal waves are affected to a lesser degree by anisotropy and can be applied for such tests. Angle beam or refracted longitudinal waves are, therefore, the accepted method for stainless steel weld inspections.

不锈钢管焊缝的相控阵超声检测

不锈钢管道和压力容器的焊缝检测是超声波检测中最具挑战性和难度的检测之一。这是由于晶粒结构和相关各向异性的变化。各向异性会导致颗粒散射，并对声波的传播产生不利影响。剪切波的影响更能说明问题，在许多情况下，剪切波几乎没有穿透焊缝体积的能力。纵波受各向异性的影响较小，可用于此类测试。因此，角束或折射纵波是不锈钢焊缝检查的公认方法。
