Full title and description

STB BS 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. This document gives standardized rules for preparing butt‑weld test pieces and extracting specimens used to determine strength and impact properties when testing welding consumables for arc welding of steel.

Abstract

Specifies preparation of butt‑weld test pieces and specimen locations for single‑run and two‑run welding techniques applied to steel. It is intended to ensure reproducible specimen geometry and welding/heat‑treatment practice when assessing weld metal tensile and impact properties of welding consumables; it is not suitable for electro‑slag or electro‑gas welding.

Scope

Applies to the preparation of butt weld test pieces and specimens used to determine mechanical (tensile) and impact properties of welded joints when testing welding consumables for arc welding of steel using single‑run and two‑run techniques. The standard defines test‑piece types, plate preparation, welding position and conditions, heat treatment allowances, and specimen extraction positions and dimensions. It excludes electro‑slag and electro‑gas welding.

Key topics and requirements

• Standardized test‑piece geometries and types for single‑run and two‑run techniques (bevels, plate thickness ranges and tolerances).
• Requirements for test‑plate material selection in line with relevant consumable classification standards.
• Assembly, clamping and preparation rules (flat assembly, no post‑weld straightening; run‑on/run‑off and backing allowances where permitted).
• Welding conditions and practice: welding in the flat position, control/measurement of preheat and interpass temperatures, and adherence to approved welding parameters.
• Heat‑treatment instructions (where required) and hydrogen‑removal provisions (timing and temperature limits).
• Specimen positions and dimensions for transverse tensile, all‑weld‑metal tensile and notched impact specimens; references to relevant test standards for specimen geometry and testing.

Typical use and users

Used by welding consumable manufacturers, independent testing laboratories, conformity assessment bodies, R&D and quality engineers to prepare reproducible test pieces for classification, product datasheets, performance testing and comparative evaluation of electrodes, fluxes and welding wires intended for arc welding of steel. Test houses performing tensile and impact testing on weld metal will use this standard to ensure specimen preparation consistency.

Related standards

Part of the ISO 15792 series (see ISO 15792‑1 and ISO 15792‑3). ISO 15792‑1 covers all‑weld‑metal test pieces for steel, nickel and nickel alloys (2020 revision); ISO 15792‑3 covers positional capacity and root‑penetration classification for fillet welds. This part also cross‑references specimen and test method standards used in mechanical testing (for example standards covering specimen geometry and tensile/impact test procedures referenced within the document).

FAQ

Q: What is this standard?

A: ISO 15792‑2:2020 (adopted as BS EN ISO 15792‑2:2020) specifies how to prepare butt‑weld test pieces and extract specimens for single‑run and two‑run welding technique tests on steel welding consumables.

Q: What does it cover?

A: It covers test‑piece geometries, plate preparation, permitted backing/run‑on arrangements, welding conditions, heat‑treatment allowances, and positions/dimensions for tensile and impact specimens used to assess weld metal properties when testing consumables for arc welding of steel. It explicitly excludes electro‑slag and electro‑gas welding.

Q: Who typically uses it?

A: Manufacturers of welding consumables, accredited test laboratories, certification and conformity assessment bodies, welding engineers and R&D teams who need consistent, repeatable specimen preparation for product classification and mechanical testing.

Q: Is it current or superseded?

A: The 2nd edition was published in 2020 and the ISO record shows the publication as the current confirmed edition (last review/confirmation recorded by ISO). National adoptions (EN, BS, etc.) were published in 2020. Consult your national standards body for the latest status and any national implementation notes.

Q: Is it part of a series?

A: Yes — ISO 15792 is a multi‑part series. Relevant parts include ISO 15792‑1 (all‑weld‑metal specimens; revised 2020) and ISO 15792‑3 (fillet weld classification tests).

Q: What are the key keywords?

A: Welding consumables, test methods, butt weld, single‑run, two‑run, specimen preparation, weld metal tensile, impact toughness, steel.
