介绍了对接焊缝错边与余高同时存在时,压力容器圆筒体焊缝余高的检测原理及方法,并提出了余高的筒化计算式。作者利用自制的固定弦长三点式组合样板测量焊缝余高,可以获得较高的检测精度。
This paper introduces the principle and method of detecting the weld seam height of the cylinder of pressure vessel while the misalignment and residual height of the butt weld occur simultaneously. The author uses the homemade fixed chord three-point combination model to measure the remaining weld heights, which can achieve higher detection accuracy.
