Visual testing requires acute precision. ISO 17637 places strict demands on the personnel executing the inspection to eliminate human error. Certification Standards iso 17637 pdf
in metallic materials. It provides the framework for ensuring that welds are inspected consistently and accurately throughout the entire fabrication process—from initial joint preparation to the final finished product. Scope and Application The standard specifically covers: Fusion-Welded Joints
The standard applies to the inspection of all types of fusion welds, including butt welds, fillet welds, and branch connections. It covers the entire lifecycle of a weld inspection, spanning pre-welding preparation, in-process monitoring, and post-welding final evaluation. The Role of the ISO 17637 PDF in Industry
magnification) are permitted to inspect fine surface cracks or micro-porosity. Removal of all slag, spatter, and protective coatings
Prior to striking the arc, the inspector verifies that the joint setup aligns with the welding procedure specification (WPS). Checks include:
Lenses with 2x to 5x magnification (preferably with an integrated scale).
Before an arc is struck, the inspector must check the fundamental geometry of the fit-up to avoid sub-surface defects. Name of the inspection body, contract details, date
For multi-pass welds, checking the weld between passes prevents subsurface defects from being buried. In-process inspection includes verifying: The cleanliness and profile of each individual weld run.
The minimum light intensity at the weld surface must be 500 lx . However, for optimal inspection accuracy and complex geometries, a level of 1000 lx is highly recommended.
