Full title and description

ISO/TR 10809-2:2011 — Cast irons — Part 2: Welding. A technical report providing guidance on welding of the family of cast iron materials, aimed at helping engineers select appropriate welding techniques and conditions for production and repair of cast-iron components.

Abstract

This Technical Report explains the fundamentals and practical considerations for welding cast irons. It describes what can and cannot be achieved when welding different types of cast iron, outlines suitable welding processes and consumables, and gives guidance on joint design, preheat and post-heat practices, and repair procedures. The document is informative (not a normative specification) and is intended to assist design and welding engineers in selecting appropriate welding methods for specific cast-iron applications.

Scope

ISO/TR 10809-2:2011 provides informative guidance on welding cast irons for both production (including finishing and joint welding) and repair operations. It covers the weldability of different cast-iron types (for example grey, ductile/spheroidal, malleable), metallurgical effects of welding, practical welding process options, filler-metal selection, thermal control (preheat/post-heat), joint design and repair techniques, and limitations on achievable properties. The report is intended to support design decisions and process selection rather than to specify mandatory procedures or acceptance criteria.

Key topics and requirements

• Overview of cast-iron types and basic metallurgical behaviour during welding (graphite form, matrix effects, cracking tendencies)
• Assessment of weldability and factors influencing successful welds (composition, section thickness, service requirements)
• Recommended welding processes and methods applicable to cast irons (fusion welding, brazing, friction welding, magnetically impelled arc welding, etc.)
• Guidance on filler metals and consumables suitable for different cast-iron grades
• Preheat, interpass temperature control and post-weld heat treatment recommendations to reduce cracking and distortion
• Joint design and repair technique guidance for production and maintenance welding
• Inspection and testing considerations for welded cast-iron components
• Limitations, achievable properties and when welding is not recommended

Typical use and users

Used by design engineers, welding engineers, foundry and casting engineers, maintenance and repair teams, fabricators, quality and inspection personnel, and educators. Typical applications include specifying repair procedures for cast-iron castings, selecting welding processes and consumables for new or refurbished components, and informing design choices where welding of cast-iron parts is anticipated.
