NBT47014-2023: For tube sheet welding procedure qualification specimens, what is the impact of triangular and square arrangements on the qualification process? Can’t figure it out
Triangle arrangement and square arrangement are different ways of arranging tubes on the tube sheet, and these different arrangements have varying effects on the stress distribution in the welds and the heat-affected zone. When conducting process evaluation, it is necessary to do so based on the actual arrangement, as this can affect the selection of welding parameters and the assessment of welding quality. Therefore, the impact of triangular and square arrangements on the evaluation mainly lies in simulating actual welding conditions to ensure the accuracy of the evaluation results. .
