Full title and description

ISO 4136:2022 — Destructive tests on welds in metallic materials — Transverse tensile test. This International Standard specifies specimen dimensions and the procedure for carrying out transverse tensile tests to determine the tensile strength and the fracture location of welded butt joints in metallic materials.

Abstract

This standard defines the transverse tensile test method for welded butt joints: specimen selection and orientation, test-piece preparation, test conditions and the procedure to apply a uniaxial tensile load across the weld until rupture so that tensile strength and fracture location of the joint can be determined. It applies to metallic materials in all product forms with welded butt joints and relies on general principles from tensile testing standards when not otherwise specified.

Scope

Specifies sizes of test specimens and the procedure for transverse tensile testing of welded butt joints to determine tensile strength and the location of fracture. The standard is applicable to welds in metallic materials of any product form and for any welded butt joint where transverse tensile testing is required. Where not otherwise specified, general principles from ISO tensile testing standards (e.g., ISO 6892 series) apply.

Key topics and requirements

• Specification of specimen dimensions, orientation and the required location of the weld axis within the specimen.
• Rules for extraction and preparation of specimens (permitted and excluded cutting/shearing methods to avoid alteration of properties).
• Test procedure: alignment, application of increasing tensile load until rupture, and determination/reporting of tensile strength and fracture location.
• Test conditions: ambient or controlled temperatures and requirements to record test temperature and any heat treatment or ageing applied to specimens.
• Marking, traceability and reporting requirements (identification of specimen origin, orientation and relevant process or post-weld treatments).

Typical use and users

Used by welding engineers, metallurgists, testing and inspection laboratories, manufacturers and quality assurance personnel to verify weld mechanical performance and to locate the fracture behaviour of butt welds. Typical applications include procedure qualification, welder testing, material conformity checks, and failure investigations in fabrication and manufacturing sectors that use welded metallic components.

Related standards

Referenced/related documents typically include tensile testing standards such as ISO 6892-1 and ISO 6892-2 (general tensile test methods), and other ISO standards on destructive tests of welds (for example standards covering longitudinal tensile tests, cruciform/lapped joint tests, and procedure/qualification standards for welding).
