Full title and description

ISO/TR 17671-2:2002 — Welding — Recommendations for welding of metallic materials — Part 2: Arc welding of ferritic steels. This technical report gives practical guidance for manual, semi-mechanized, mechanized and automatic arc welding of ferritic steels (excluding ferritic stainless steels) across a range of product forms, and explains detrimental phenomena that can occur with advice on how to avoid them.

Abstract

Provides recommendations and guidance to support satisfactory arc welding of ferritic steels, addressing joint preparation, welding processes, preheating, interpass temperature, and actions to reduce common detrimental effects in the weld and heat‑affected zone. The document is intended to be generally applicable regardless of fabrication type, while allowing for additional requirements from specific application standards.

Scope

Gives guidance for arc welding of ferritic steels (excluding ferritic stainless steels) in all product forms. It covers manual, semi‑mechanized, mechanized and automatic arc welding methods, describes possible detrimental phenomena (for example those affecting weld metal and heat‑affected zones) and provides practical advice on joint preparation, welding parameters, preheat and interpass control, and measures to avoid welding defects. Application standards may impose additional requirements beyond this technical report.

Key topics and requirements

• Joint preparation and fit-up recommendations for arc welding ferritic steels.
• Guidance on selection of welding processes (manual, semi‑mechanized, mechanized, automatic) and suitable welding parameters.
• Preheating, interpass temperature control and post‑weld heat treatment considerations to reduce risk of hydrogen‑induced cracking and adverse HAZ properties.
• Discussion of common detrimental phenomena (weld metal/HAZ cracking, hardening, excessive distortion) and mitigation strategies.
• References to related normative guidance (grouping systems and measurement methods) to support implementation.

Typical use and users

Used by welding engineers, metallurgists, fabricators, quality managers, standards committees and technical specifiers to develop welding procedures, training material and fabrication instructions for ferritic steel components and structures. It supports writers of application standards and procedure qualification documents seeking practical, process‑level guidance.

Related standards

Closely related to other parts of the ISO/TR 17671 series (Part 1: General guidance for arc welding; Part 3: Arc welding of stainless steels) and to ISO/TR 15608 (material grouping system) and ISO 13916 (measurement of preheating and interpass temperatures). Users commonly consult Part 1 for general fusion‑welding guidance and Part 3 for stainless steel–specific recommendations.
