Pro tip: Some national bodies offer a "read-only" PDF for a lower price, but you cannot print or copy-paste. For field use, buy the full PDF license.
ISO 17637 is rarely used in isolation. It is the "how-to" guide for inspection, but it is usually paired with:
In a typical project specification, ISO 17637 tells you how to look, and ISO 5817 tells you what constitutes a defect (e.g., how big a pore is allowed to be).
While the search for a free ISO 17637 PDF is tempting, the risks of using an illegitimate copy far outweigh the benefits. Visual testing is the first line of defense against weld failure, and using the wrong version (or a corrupted file) could lead to catastrophic structural failures or costly litigation.
Invest in the official document from the ISO store or your national standards body. By doing so, you ensure you are working with the latest legal requirements, clear diagrams, and accurate measurement clauses.
Remember: ISO 17637 gives you the method. Pair it with ISO 5817 (for acceptance) and your client’s specific code requirements. Whether you are inspecting a pipeline, a skyscraper beam, or a submarine hull—this standard ensures that what you see is truly what you get.

ISO 17637:2016 is the primary international standard for the visual testing (VT) of fusion-welded joints
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
: It applies to any metallic material joined via fusion welding. Pre-Welding Inspection
: Verification of the joint preparation, including shape and dimensions. In-Process Inspection
: Monitoring the weld during the process, ensuring each layer is cleaned before the next is applied. Post-Welding Inspection
: Evaluation of the finished weld, its profile, dimensions, and surfaces. Key Technical Requirements
ISO 17637 defines critical environmental and procedural conditions to ensure inspection reliability: Illuminance (Lighting)
: 350 lux is the absolute minimum requirement for the surface being inspected. Recommended
: 500 lux is generally recommended for better detection of fine defects.
: Using tinted safety goggles or sunglasses increases the minimum lux requirement for the inspector. Personnel Qualification iso 17637 pdf
: Inspectors must have appropriate knowledge and experience in welding and visual testing. Many regional versions, like BS EN ISO 17637
, emphasize that personnel should be trained and qualified to recognized industry standards.
: Common tools used under this standard include magnifying glasses (typically 2x to 5x), weld gauges for measuring fillet size and reinforcement height, and flashlights or boroscopes for internal root inspections. Visual Inspection Stages
The standard breaks down the inspection into three distinct phases: Before Welding
: Inspectors check for contaminants (oil, rust), correct bevel angles, and proper fit-up/alignment. During Welding
: Observation of the arc, slag removal between passes, and checking for obvious defects like cracks or lack of fusion before they are buried by subsequent layers. After Welding
: The finished weld is checked for cleaning, overall profile, and surface defects such as undercut, porosity, or overlap. Standard Evolution and Availability Current Version : ISO 17637:2016. Superceded Standards : It replaced older national standards such as in Europe and in Turkey. Official Access : While summaries are available on platforms like

The standard outlines specific technical requirements to ensure that visual inspections are reliable and standardized across the industry. Testing Conditions & Environment Illuminance : A minimum surface light level of is required, though is strongly recommended for better visibility. : The inspector's eye should ideally be within of the surface, with a viewing angle not less than 30 raised to the composed with power Personnel Qualifications
: Inspectors must be appropriately qualified and experienced to identify surface discontinuities and interpret results. Inspection Phases Before Welding
: Checking joint preparation, including shape, dimensions, and cleanliness. During Welding
: Ensuring each run or layer is cleaned and free of defects before the next is applied. After Welding
: Examining the finished weld for profile accuracy, dimensions, and the absence of surface-breaking defects like cracks or porosity. Typical Inspection Checklist Requirement Weld Profile
Must be smooth and even, avoiding excessive convexity or concavity. Surface Defects No cracks, porosity, or lack of fusion are permitted.
All slag and spatter should be removed for a clear inspection. Dimensions Weld size must meet the specifications defined in the Welding Procedure Specification (WPS) Where to Access the PDF

Viewing Conditions: For direct inspection, the inspector's eye should be within 600 mm of the weld surface and positioned at an angle of at least 30 degrees.
Remote Inspection: When direct access is restricted, tools like mirrors, boroscopes, fiber-optic cables, or cameras are permitted.
Personnel Qualification: Inspection and evaluation must be performed by qualified personnel. It is recommended that they be certified according to ISO 9712 or an equivalent industry-recognized standard. Critical Inspection Stages
ISO 17637 is not limited to finished welds; it covers the entire welding lifecycle to prevent defects early. Inspection Stage Key Checklist Items Pre-Weld
Verify joint preparation dimensions, cleanliness, and correct assembly (fit-up) per the Welding Procedure Specification (WPS). During Welding
Inspect individual runs/layers for cleanliness and visible defects like cracks or cavities before adding the next layer. Post-Weld
Assess the finished weld profile, dimensions, and root conditions. Check for proper cleaning and removal of slag. Repaired Welds
Re-inspect repaired areas using the same original requirements to ensure all imperfections were effectively removed. Acceptance Criteria and Reference Standards
ISO 17637 itself does not specify numerical limits for defects. Instead, it is used in conjunction with application-specific standards that define quality levels: ISO 17637:2003(en), Non-destructive testing of welds
