标准中对于焊缝射线检测透照厚度比有着明确的规定,根据这些规定可以计算透照角度,从而计算透照次数。但是一些特殊情况如柱面对接环形焊缝的射线检测,根据透照厚度比计算透照次数相对复杂,本文通过数学计算证明,给出了柱面对接环焊缝的透照次数和相应的透照布置,可用于指导实际检测。
The standard for the penetration of ray-ray detection of weld thickness ratio has a clear rule, according to these provisions can calculate the perspective of transillumination to calculate the number of transillumination. However, in some special cases, such as cylindrical abutting annular weld ray detection, according to the transillumination thickness than the calculation of the number of transillumination is relatively complicated, this paper through mathematical calculations show that the cylindrical abutting ring weld penetration number and corresponding The translucent layout, can be used to guide the actual test.
