In this article, we will explain what ISO/TR 20173 is, what benefits it offers, what challenges it poses, and how you can get it for free. We will also show you some examples of how to use it in practice and give you some tips for improving your welding quality management.


How to get ISO/TR 20173 for free?




ISO/TR 20173 is a document published by the International Organization for Standardization (ISO), a worldwide federation of national standards bodies that develops and publishes voluntary standards for various fields and industries. The document was first published in 2005 and has been revised twice, in 2009 and 2018. The latest edition, ISO/TR 20173:2018, covers grouping systems for the following standardized materials:


  • steel;



  • aluminium and its alloys;



  • nickel and its alloys;



  • copper and its alloys;



  • titanium and its alloys;



  • zirconium and its alloys;



  • cast irons.



The document also includes a number of Canadian, Australian and New Zealand materials commonly used in North America.


The purpose of ISO/TR 20173 is to provide an American grouping system for materials for welding purposes, classified in accordance with the grouping system of ISO/TR 15608. This means that the document helps you to identify which materials are similar or dissimilar in terms of weldability, mechanical properties, chemical composition, and metallurgical behaviour. This can help you to select appropriate welding consumables, procedures, parameters, and quality control methods for your welding projects.


Some of the benefits of using ISO/TR 20173 are:


  • It simplifies the selection of welding consumables by providing a common reference for different materials;



  • It reduces the risk of errors, defects, failures, and rework by ensuring compatibility and consistency between materials and welding processes;



  • It enhances the quality, safety, performance, and reliability of welded products by following internationally recognized standards and best practices;



  • It facilitates communication and cooperation among welders, engineers, inspectors, customers, suppliers, regulators, and other stakeholders by using a common language and terminology.



However, ISO/TR 20173 also has some challenges and limitations that you should be aware of:


  • It is not a mandatory or legally binding document, but rather a guidance document that provides recommendations and suggestions. You are still responsible for verifying the suitability and applicability of the document to your specific situation and needs;



  • It does not cover all possible materials or combinations of materials that may be encountered in welding practice. You may need to consult other sources or experts for additional information or guidance;



  • It does not provide detailed instructions or specifications on how to perform welding operations or tests. You may need to refer to other standards or codes for more technical details or requirements;



  • It may not reflect the latest developments or innovations in materials or welding technology. You may need to update your knowledge and skills regularly to keep up with the changes in the industry.



If you want to get ISO/TR 20173 for free, you have a few options:Carbon steel


Gas metal arc welding (GMAW)


You can use ISO/TR 20173 to find the American grouping number of the carbon steel base metal and the filler metal, and then compare them to see if they are compatible. For example, if the base metal is ASTM A36, which has a grouping number of 1.1, and the filler metal is AWS A5.18 ER70S-6, which also has a grouping number of 1.1, then they are compatible and can be welded together. However, if the base metal is ASTM A516 Grade 70, which has a grouping number of 1.2, and the filler metal is AWS A5.18 ER70S-6, which has a grouping number of 1.1, then they are not compatible and may require preheating, post-weld heat treatment, or other special measures to prevent cracking or other defects.


Aluminium alloy


Gas tungsten arc welding (GTAW)


You can use ISO/TR 20173 to find the American grouping number of the aluminium alloy base metal and the filler metal, and then compare them to see if they are compatible. For example, if the base metal is AA 6061-T6, which has a grouping number of 23, and the filler metal is AWS A5.10 ER4043, which also has a grouping number of 23, then they are compatible and can be welded together. However, if the base metal is AA 2024-T3, which has a grouping number of 21, and the filler metal is AWS A5.10 ER4043, which has a grouping number of 23, then they are not compatible and may require special techniques or procedures to achieve acceptable welds.


Nickel alloy


Shielded metal arc welding (SMAW)


You can use ISO/TR 20173 to find the American grouping number of the nickel alloy base metal and the filler metal, and then compare them to see if they are compatible. For example, if the base metal is UNS N06625 (Inconel 625), which has a grouping number of 43, and the filler metal is AWS A5.11 ENiCrMo-3, which also has a grouping number of 43, then they are compatible and can be welded together. However, if the base metal is UNS N08825 (Incoloy 825), which has a grouping number of 42, and the filler metal is AWS A5.11 ENiCrMo-3, which has a grouping number of 43, then they are not compatible and may require matching filler metals or other precautions to avoid weld failures.


These are just some examples of how to use ISO/TR 20173 in practice. You can apply the same logic to other materials and welding processes as well. However, you should always remember that ISO/TR 20173 is not a substitute for your own judgment and experience. You should always verify the suitability and applicability of the document to your specific situation and needs.


Conclusion




ISO/TR 20173 is a technical report that provides an American grouping system for materials for welding purposes, classified in accordance with the grouping system of ISO/TR 15608. It can help you to simplify the selection of welding consumables, reduce the risk of errors and defects, enhance the quality and safety of welded products, and facilitate communication and cooperation among stakeholders.


However, ISO/TR 20173 also has some challenges and limitations that you should be aware of. It is not a mandatory or legally binding document, but rather a guidance document that provides recommendations and suggestions. It does not cover all possible materials or combinations of materials that may be encountered in welding practice. It does not provide detailed instructions or specifications on how to perform welding operations or tests. It may not reflect the latest developments or innovations in materials or welding technology.


If you want to get ISO/TR 20173 for free, you have a few options. You can download it from the official ISO website if you are a member or a subscriber, or from other websites that offer free downloads of standards. You can also borrow it from a library, a colleague, a friend, or a professional association that has a copy of it.


Once you have obtained ISO/TR 20173, you can use it in practice by finding the American grouping number of the base metal and the filler metal, and comparing them to see if they are compatible. You can also refer to other standards or codes for more technical details or requirements.
