Full title and description

STB DIN EN ISO 13919-1:2020-03 — Welding — Guidance for quality levels for imperfections — Part 1: Metallic materials (ISO 13919-1:2019, adopted as EN ISO and published as a national standard).

Abstract

This standard gives guidance for establishing acceptance levels for welding imperfections in metallic materials. It specifies quality levels that can be used to evaluate the acceptability of imperfections found in welded joints, and provides illustrative diagrams and dimensional limits for common imperfection types. The standard is intended to support designers, fabricators, weld inspectors and quality managers in defining and applying quality criteria for welded components and assemblies.

Scope

ISO 13919-1 provides guidance on establishing quality levels for imperfections detected in welded joints of metallic materials. It defines quality levels (e.g., B, C, D or numbered levels) and gives representative illustrations and dimensional limits for defects such as porosity, inclusions, undercut, lack of fusion, cracks, and excessive convexity or concavity. The document is intended for use where acceptance criteria are not specified by the purchaser, design code or regulatory authorities and can be referenced in specifications to indicate the required level of acceptability.

Key topics and requirements

• Definition and classification of common welding imperfections in metallic materials.
• Establishment of quality levels and corresponding acceptance criteria for imperfections.
• Illustrative diagrams and dimensional limits for defects (porosity, slag inclusions, undercut, overlap, incomplete fusion, cracks, etc.).
• Guidance on selection of appropriate quality level depending on service, safety and inspection method.
• Recommendations for specification in procurement and inspection documents when no other criteria apply.

Typical use and users

Used by welding engineers, fabricators, inspectors, quality managers, designers and procurement specialists to define or apply acceptance criteria for weld imperfections in metallic assemblies. It is commonly referenced in welding specifications, quality plans, inspection procedures, and by certification bodies when assessing welded construction where prescriptive codes do not provide specific limits.
