Determination of the minimum times of digital radiography needed for pipeline girth weld
There is no simple and effective method to determine the minimum times of digital radiography needed for pipeline girth weld. And the minimum times deduced by referencing to RT has great limitations directly. Based on SY/T 4109. 5-2013, this paper analyzes the factors affecting the minimum times for DWSI and SWSI respectively, and proposes a calculation formula for NDT personnel.
