ISO/TR 10809-2:2011的目的是帮助设计工程师了解和掌握铸铁材料族的焊接方法，并充分利用该技术为特定铸铁选择最合适的技术。由于焊接技术的应用和焊接的冶金影响不是通常教给工科学生的科学学科，因此这些用户对铸铁焊接技术的基础知识往往知之甚少。ISO/TR 10809-2:2011解释了什么可以实现，什么不能实现以及为什么。它不是为焊接技术设计的教科书。它帮助用户为特定应用选择最合适的焊接工艺和条件。 ISO/TR 10809-2:2011涵盖了生产（包括精加工和接头焊接）和补焊。

The purpose of ISO/TR 10809-2:2011 is to assist the design engineer to understand and to acquire knowledge of how the family of cast iron materials can be welded and to utilize this technology to its full advantage in selecting the most appropriate technique for a particular cast iron. Because the application of welding technology and the metallurgical implications of welding are not scientific disciplines normally taught to engineering students, such users often have limited knowledge of the fundamentals underpinning welding technology for cast irons. ISO/TR 10809-2:2011 explains what can be achieved, what cannot be achieved and why. It is not designed to be a textbook of welding technology. It helps users to select the most appropriate welding process and conditions for a specific application. ISO/TR 10809-2:2011 covers production (including finishing and joint welding) and repair welding.
