dictates WHAT is acceptable (the quality levels for imperfections).
Checking the placement, size, and quality of any tack welds used to hold the assembly together. Phase 2: During Welding (Interpass Inspection)
Searching for is the first step. The second step is ensuring you obtain the legitimate, current version from an accredited standards provider. The third and most important step is implementing the standard correctly – training your staff, calibrating equipment, and producing compliant reports.
ISO 17637 (16 pages, including annexes) is organized into key sections that guide the inspector through the process: iso 17637 pdf
Designed for fusion welding processes (e.g., MIG, TIG, MMA, SAW).
Re-inspect repaired areas using the same original requirements to ensure all imperfections were effectively removed. Acceptance Criteria and Reference Standards
Inspecting the surrounding base metal for arc strikes or tool gouges. Documenting the Visual Inspection Report dictates WHAT is acceptable (the quality levels for
The inspector’s eye must be positioned within 600 mm of the weld surface. The viewing angle relative to the surface must not be less than 30 degrees .
A: Single-user licenses prohibit sharing. For a team of 5+ inspectors, buy a multi-user or corporate license from ANSI or the ISO store.
: Verification of the joint preparation, including shape and dimensions. In-Process Inspection The second step is ensuring you obtain the
Once welding is complete and the joint has cooled sufficiently, the final evaluation takes place. The weld is assessed across its entire length to identify surface-breaking defects such as: Undercutting at the toe of the weld. Excessive or insufficient weld reinforcement (cap height). Surface porosity, blowholes, and crater cracks.
If your project follows ISO or EN standards, . If it follows AWS or ASME, you will use those respectively, though ISO 17637 remains a good reference.
Visual testing requires acute precision. ISO 17637 places strict demands on the personnel executing the inspection to eliminate human error. Certification Standards
