Overview

EN ISO 17641-1:2004 - Destructive tests on welds in metallic materials - Hot cracking tests for weldments - Arc welding processes - Part 1: General (ISO 17641-1:2004) is a CEN-adopted ISO standard that provides an introduction to the fundamentals of hot cracking (solidification cracking) in weld metals and parent alloys and gives a concise description of the destructive test methods available for arc welding processes. This Part 1 document is a general, non-prescriptive overview intended to help readers understand the phenomenon and the range of test approaches used to detect and assess hot cracking susceptibility.

Key Topics

• Fundamentals of hot cracking: conceptual explanation of how hot cracking develops in weld metal and adjacent parent material during solidification and cooling.
• Overview of test categories: descriptive coverage of the main types of destructive tests used for arc welding processes (purpose and scope rather than step-by-step procedures).
• Factors affecting cracking: general discussion of metallurgical, thermal and process variables that influence hot cracking susceptibility (material composition, solidification behavior, welding parameters).
• Test selection guidance: brief guidance on how different tests relate to practical welding situations and what they aim to reveal about weldability and crack susceptibility.
• Terminology and scope: standardized terms and the intended scope for hot cracking evaluation in arc welding contexts.

Note: As a general part, EN ISO 17641-1:2004 summarizes test principles rather than specifying detailed test procedures or acceptance criteria.

Applications

EN ISO 17641-1:2004 is useful for:

• Welding engineers and fabricators selecting appropriate destructive tests when evaluating weldability or troubleshooting hot cracking problems.
• Materials and metallurgical laboratories seeking a conceptual framework for hot cracking assessment before applying specific test methods.
• Quality assurance and inspection teams who need to understand the limitations and purposes of destructive crack tests for arc-welded joints.
• Standards committees and researchers who require a common terminology and overview of available test approaches for arc welding processes.

Practical benefits include improved test selection, clearer interpretation of destructive test results, and better-informed welding procedure development to mitigate hot cracking risk.

Related Standards

• Other parts of the ISO 17641 series (test-specific parts) and complementary ISO/CEN welding standards address detailed procedures, specimen geometries and acceptance criteria. Consult the full ISO 17641 series and relevant welding procedure qualification standards for prescriptive test methods.
