ISO 17637 outlines duties across the entire fabrication lifecycle: ISO 17637:2016 - Visual testing of fusion-welded joints
ISO 17637 is an international standard published by the International Organization for Standardization (ISO) that focuses on non-destructive testing (NDT) and specifically deals with "Non-destructive testing - Radiation methods - Computed radiography". iso 17637 pdf
There — just beneath the toe of the weld, running parallel to the joint — a hairline crack. Not yet open to the surface, but visible under magnification. The standard’s Table 2 was explicit: any crack, regardless of size, is unacceptable for Class B. ISO 17637 outlines duties across the entire fabrication
ISO 17637 divides the inspection process into three distinct phases to ensure structural integrity : INTERNATIONAL STANDARD ISO 17637 The standard’s Table 2 was explicit: any crack,
standard, titled " Non-destructive testing of welds — Visual testing of fusion-welded joints
"You threw out the international standard for non-destructive testing of welds?" Elias asked, his voice dangerously quiet. "That’s a massive violation in itself."
