摘要

本文介绍了对接焊接接头的硬度分布、宏观组织和微观组织测试结果。对G17CrMo5-5焊接接头冲击断口的表面形态进行了分析。焊接过程是在两种类型的熔体上进行的，即不进行变质处理和在液态金属中添加稀土金属（REM）。焊接接头采用TIG焊接方法。

Analiza morfologii przełomów udarnościowych złączy spawanych ze staliwa dla energetyki typu Cr-Mo z dodatkiem metali ziem rzadkich

The article presents the results of tests of butt welded joints, ie. hardness distribution, macro and microstructure. Analysis of surface morphology of impact fractures of G17CrMo5-5 welded joints was carried out. The welding process was carried out on two types of melts, ie. without modification and with addition of rare earth metals (REM) to liquid metal. Welded joints were made using the TIG method.
