Full title and description

Fatigue — Fatigue testing of welded components — Guidance. This technical report gives guidance on best practice for fatigue testing (constant- or variable-amplitude) of welded components in the medium- and high-cycle regimes, and covers specimen manufacture, preparation, presentation and evaluation of results.

Abstract

ISO/TR 14345:2012 provides practical guidance for performing fatigue tests on welded components where nominal stresses do not exceed yield. It concentrates on medium‑ and high‑cycle fatigue under stress control (constant or variable amplitude), describes the steps for manufacturing and preparing welded test specimens, and gives recommendations for presenting and evaluating test results. The report explicitly excludes corrosion and high‑temperature fatigue testing and does not specifically treat low‑cycle fatigue under strain control.

Scope

Provides guidance on fatigue testing of welded components in the medium‑ and high‑cycle regimes under constant‑ or variable‑amplitude loading where applied nominal stresses remain below yield. It covers specimen design and manufacture, weld preparation, test procedures in stress‑control regimes, and the presentation and evaluation of fatigue test results. It does not cover corrosion‑ influenced fatigue or high‑temperature fatigue and does not specifically address low‑cycle, strain‑controlled testing.

Key topics and requirements

• Recommended best practices for fatigue testing of welded components (constant and variable amplitude).
• Guidance on specimen manufacture, welding procedures for test specimens, and specimen preparation/finishing.
• Test set‑up and execution considerations for medium‑ and high‑cycle fatigue under stress control.
• Presentation, reporting and evaluation of test results, including data treatment and interpretation for welded joints.
• Explicit exclusions: corrosion‑fatigue, high‑temperature fatigue; low‑cycle, strain‑controlled testing is not the primary focus.

Typical use and users

Used by structural and mechanical engineers, welding engineers, materials and metallurgical laboratories, fatigue testing facilities, research organizations, and certification bodies involved in the assessment of welded structures and components. It is applied when establishing or harmonizing laboratory procedures, validating test methods, preparing test reports, or comparing fatigue data for welded joints.

Related standards

National and regional bodies have published or sold reproductions/adoptions (for example BSI and DIN catalog entries for PD/ISO/TR 14345:2012). Related documents include other ISO/IEC/BSI/DIN standards and test methods covering fatigue testing, statistical analysis of fatigue data, and welding practice; users often consult national standards and recognized test methods (e.g., comparable ASTM fatigue test methods) alongside this report when specifying or performing tests.
