                   要求。针对聚变堆真空室T型焊缝,使用相控阵超声检测的方式控制焊缝质量。然而焊缝粗晶的
                   组织特征和真空室的复杂结构给相控阵超声检测带来了挑战。针对此问题,首先通过CIVA软件对
                   探头焦点和焦柱尺寸进行仿真计算,并根据计算结果为检测方案设计提供参考,然后设计了使用双
                   面阵探头在腹板侧面激发扇形扫查,结合线阵探头在翼板外侧面激发角度垂直于熔合线的线性扫
                   查的检测方案,对预埋有典型焊接缺陷的模拟试块进行了检测,实现了缺陷的全检出。该检测方案
                   可为T型焊缝检测的实际应用提供参考。

                      Abstract: As the core component of the fusion reactor device, the weld bevel of the vacuum chamber requires full
                   weld penetration, and the welding quality has strict requirements. In this paper, phased array ultrasonic inspection was
                   used to control the quality of T-shaped welds in the vacuum chamber of a fusion reactor. However, the coarse crystalline
                   organization of the weld and the complex structure of the vacuum chamber brought challenges to the phased array ultrasonic
                   inspection. In this paper, the simulation calculation of the probe focus and focal column size was performed by CIVA
                   software, and the results provided reference for the design of the inspection scheme, and then the full detection of defects
                   was achieved by using the inspection scheme of fan sweeping excited by a double-sided array probe on the side of the web,
                   and linear sweeping with an angle perpendicular to the fusion line excited by a line array probe on the outer side of the wing
                   plate to inspect the demonstration block with typical weld defects. The inspection program can provide guidance for the
                   inspection of T-welds in practical applications.
