Full title and description

Resistance welding — Testing of welds — Peel and chisel testing of resistance spot and projection welds. This international standard specifies recommended procedures and tooling for performing peel and chisel tests on resistance spot and embossed projection welds to assess weld dimensions and failure modes and to verify weld quality by non‑destructive chisel testing.

Abstract

This document prescribes the procedures and recommended tooling to be used for peel and chisel testing of resistance spot and embossed projection welds. It applies to welds made in two or more sheets with sheet thicknesses in the range 0.5 mm to 3.0 mm. The tests aim to determine weld size and failure mode when welds are destructively tested and to permit verification of welds by non‑destructive chisel tests. The standard notes that mechanized peel testing for seam welds is covered by ISO 14270.

Scope

Specifies the procedures and recommended tooling for peel and chisel testing of resistance spot and embossed projection welds in assemblies of two or more sheets having sheet thicknesses between 0.5 mm and 3.0 mm. The scope covers test specimen preparation, test execution (peel and chisel), observation and recording of failure mode, and use of chisel tests for verification of welds where destructive peel testing is not appropriate. The document explicitly indicates mechanized peel testing of seam welds is covered elsewhere (ISO 14270).

Key topics and requirements

• Defined procedures for manual peel testing of spot and projection welds.
• Recommended tooling and fixture arrangements for peel and chisel tests.
• Applicable sheet thickness range: 0.5 mm to 3.0 mm.
• Objectives: determine weld size and failure mode under destructive testing; permit verification using non‑destructive chisel tests.
• Requirements for specimen preparation, test orientation, and recordkeeping of results and observed failure modes.
• Cross‑reference: mechanized peel testing of seam welds is handled in ISO 14270.

Key procedural and scope elements summarized from the ISO standard description.

Typical use and users

Used by welding engineers, quality and inspection personnel, metallurgical and mechanical test laboratories, OEM manufacturing quality teams (automotive, aerospace, white goods, heavy industry), standards committees and training organizations. Typical applications include production verification of spot/projection welds, failure‑mode analysis during qualification testing, and routine non‑destructive chisel checks during quality control.

Related standards

ISO 14270 (mechanized peel testing of seam welds) is explicitly referenced by ISO 10447:2022 for seam‑weld peel testing methods. ISO 10447 is issued under the work of ISO/TC 44/SC 6 (resistance welding) and complements other ISO and regional welding‑test standards used for weld quality assessment.

FAQ

Q: What is this standard?

A: An ISO international standard specifying procedures and recommended tooling for peel and chisel testing of resistance spot and projection welds to evaluate weld size and failure mode and to provide a chisel test method for verification.

Q: What does it cover?

A: It covers manual peel testing and chisel testing procedures, specimen preparation, recommended tooling and fixtures, applicable thickness range (0.5 mm to 3.0 mm), and the purposes of the tests (destructive determination of weld size/failure mode and non‑destructive verification by chisel tests).

Q: Who typically uses it?

A: Welding engineers, production and quality inspectors, test laboratories, OEM and supplier quality teams in automotive, aerospace, appliance and general manufacturing, and organizations performing weld qualifications and failure investigations.

Q: Is it current or superseded?

A: Current. ISO 10447:2022 (Edition 4, published November 2022) is the active edition; it replaces ISO 10447:2015.

Q: Is it part of a series?

A: It is part of the body of ISO resistance‑welding standards developed under ISO/TC 44/SC 6; related documents address other test methods and seam‑weld mechanized peel testing (for example ISO 14270).

Q: What are the key keywords?

A: Resistance welding, spot weld, projection weld, peel test, chisel test, weld testing, nondestructive verification, destructive testing, weld failure mode.
