Full title and description

ISO 10446:1990 — Welding — All-weld metal test assembly for the classification of corrosion-resisting chromium and chromium‑nickel steel covered arc welding electrodes. Describes the preparation and welding of an all‑weld metal test assembly used to classify the mechanical properties of corrosion‑resisting chromium and chromium‑nickel covered‑arc electrodes.

Abstract

This International Standard specifies the procedure for preparing and welding an all‑weld metal test assembly so that deposited weld metal from covered arc welding electrodes can be compared and classified. Recommended electrode diameters for testing are 3.2 mm to 5.0 mm; the procedure includes details for preparation of deposited weld metal and the test assembly backing.

Scope

Specifies the method for preparing and depositing weld metal in an all‑weld metal test assembly used to classify corrosion‑resisting chromium and chromium‑nickel steel covered arc welding electrodes. The scope is limited to providing a consistent specimen geometry and welding procedure so that mechanical test results (tensile, impact, etc.) from deposited weld metal are comparable between electrode types and origins. Recommended electrode diameters for testing are 3.2 mm to 5.0 mm.

Key topics and requirements

• Definition and preparation of an all‑weld metal test assembly (specimen geometry and backing arrangement).
• Welding procedure details to deposit test weld metal representative of covered‑arc electrodes.
• Recommended electrode diameters for test pieces (3.2 mm to 5.0 mm).
• Requirements to permit comparable mechanical testing of deposited weld metal from different electrode sources (so classification is consistent).

Typical use and users

Used by manufacturers of covered arc welding electrodes, welding research and testing laboratories, conformity assessment bodies, standards committees, and industrial users who need to classify and compare the mechanical properties of deposited weld metal from corrosion‑resisting chromium and chromium‑nickel electrodes. The standard supports quality control, product classification, and comparative testing.

Related standards

Belongs to the suite of ISO and IIW standards on welding and welding consumables under ISO/TC 44. Other related standards cover classification and testing of welding consumables (for example various ISO standards on electrode and wire classifications and testing methods). Note that several historical ISO welding standards have subsequently been reviewed or withdrawn as the committee work evolved.

FAQ

Q: What is this standard?

A: ISO 10446:1990 is an ISO international standard titled "Welding — All‑weld metal test assembly for the classification of corrosion‑resisting chromium and chromium‑nickel steel covered arc welding electrodes", describing how to prepare and weld test assemblies used to classify covered‑arc electrodes.

Q: What does it cover?

A: It covers the preparation and welding of an all‑weld metal test assembly and the associated requirements to produce deposited weld metal suitable for mechanical classification and comparison, with recommended electrode diameters of 3.2 mm to 5.0 mm.

Q: Who typically uses it?

A: Electrode manufacturers, test laboratories, conformity assessment bodies, welding engineers, and standards committees involved in classification and comparative testing of welding consumables.

Q: Is it current or superseded?

A: ISO 10446:1990 has been withdrawn. National sources list it as withdrawn (withdrawal noted in national catalogs); there is no widely cited single direct replacement listed on the ISO catalogue entry. Users should consult current ISO/TC 44 documents and more recent ISO welding‑consumable standards for up‑to‑date classification and testing methods.

Q: Is it part of a series?

A: It is part of the body of welding and welding‑consumable standards developed under ISO/TC 44 and in collaboration with the International Institute of Welding (IIW). Related classification and testing standards for welding consumables appear elsewhere in the ISO/TC 44 portfolio.

Q: What are the key keywords?

A: Welding; all‑weld metal test assembly; covered arc electrode; stainless/chromium‑nickel steels; electrode classification; deposited weld metal; mechanical testing; IIW; ISO.
