本CWA为测量钢板中易发生氢脆现象的扩散氢含量提供了一套指南。从钢铁生产到零件制造，直到部件的使用寿命，氢的吸收可以在几个过程中发生。 目前的风险评估方法包括复杂的实验室测试，包括耗时的样品制备和长时间的测试。这些程序不适用于快速、简单且可能无需维护的工业监控- 需要侵入式Metodology。 在该框架中，HELIOS 4热探针在工业规模上执行非破坏性扩散氢测量方法，以评估高强度钢零件的安全操作。该创新技术允许直接在金属板卷和零件上进行测量，最终在过程失控时立即采取纠正措施，提高最终用户的安全性。

This CWA provides a set of guidelines for the measurement of diffusible hydrogen content in steel sheets, that can be susceptible to hydrogen embrittlement phenomenon. Hydrogen pick up can take place in several processes from steel production, through part manufacturing, till the service life of component. Current risk assessment methods consists in complicated laboratory tests that involve time consuming sample preparation and long test duration. These procedure are not suitable for industrial monitoring where quick, easy and possibly non-intrusive metodologies are required. In this framework, the HELIOS 4 HOT PROBE performs non-destructive diffusible hydrogen measuring method at industrial scale, in order to assess the safe operation of high strength steel parts. The innovative technique allows measurements directly on sheet metal coils and parts, to eventually immediately apply corrective actions in case of process out of control, increasing the safety of the final user.
