Overview

EN ISO 15792-2:2020 - "Welding consumables - Test methods - Part 2: Preparation of single-run and two-run technique test pieces and specimens in steel" - specifies how to prepare butt-weld test pieces and specimens used to determine the strength and impact properties of welded joints when testing welding consumables for arc welding of steel. It applies to single-run and two-run techniques and is not suitable for electro‑slag or electro‑gas welding.

Key topics and requirements

• Scope: Preparation of butt weld test pieces for testing welding consumables (arc welding of steel); excludes electro‑slag/gas methods.
• Test-piece types: Several standardised test-piece configurations (types 2.1–2.6) with defined plate thicknesses, bevels and tolerances to represent single-run and two-run techniques.
• Material: Test plate material shall follow the relevant consumable classification standard.
• Assembly & preparation:
  • Plates must be preset/restrained to produce a flat welded test piece; the welded assembly shall not be straightened afterwards.
  • Backing systems and run‑on/run‑off plates are permitted for single‑run technique.
  • If thermal cutting is used, provide at least 10 mm machining allowance on either side.
• Welding conditions:
  • Welding performed in the flat position.
  • Start at room temperature or after required preheating; interpass and preheat temperatures measured (e.g., thermocouples, crayons) and controlled per consumable standard.
  • Welding parameters (current, voltage, travel speed, bead size) must be within manufacturer recommendations and, for classification, within the consumable standard limits.
• Heat treatment:
  • All required heat treatments (except hydrogen-removal) applied to completed test piece or sections with machining allowance.
  • Hydrogen removal may be done before or after final machining; may be held ≤250 °C for up to 16 h.
• Specimen location & dimensions:
  • Positions for notched impact specimens, transverse tensile and all-weld-metal tensile specimens shown in figures; follow ISO 9016, ISO 4136 and ISO 5178 for specimen geometry and testing.
  • Typical impact specimen sizes: 10 × 10 mm (subsize 5 × 10 mm where applicable).

Applications

• Classification and performance testing of welding consumables (fluxes, electrodes, tubular cored wires) intended for arc welding of steel.
• Laboratory test programs to determine weld metal tensile strength and impact toughness for product datasheets, conformity assessment and R&D.
• Defining consistent specimen preparation for comparative testing across manufacturers and test houses.

Who should use this standard

• Welding consumable manufacturers and product development teams
• Independent test laboratories and certification bodies
• Quality, welding and metallurgical engineers involved in consumable selection and validation
• Standards committees and technical assessors preparing conformity reports

Related standards

• ISO 4136 - Transverse tensile test on welds
• ISO 5178 - Longitudinal tensile test on weld metal
• ISO 9016 - Impact tests - specimen location and notch orientation
• ISO 13916 - Temperature-measurement guidance for preheat/interpass

Using EN ISO 15792-2:2020 ensures reproducible preparation of butt-weld test pieces for reliable evaluation of welding consumables under single‑run and two‑run welding techniques.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
