摘要

耐热镍合金是制造高温核电站结构件的理想材料。镍合金是一种难以焊接的材料，这是限制其使用的主要因素之一。本文介绍了耐热镍合金牌号 CrNi62MoCh2-VI（EC 199-VI）焊接技术的开发和工业应用成果。本文还介绍了焊接接头的质量控制结果。值得注意的是，CrNi62MoCh2-VI 合金的焊接接头具有抗晶间腐蚀的性能，并显示出更好的机械特性。

Development and industrial exploitation of welding technology for heat-resistant nickel alloys for high-temperature nuclear power plants

Heat-resistant nickel alloys are promising materials for manufacturing structural elements used in high-temperature nuclear power plants. Nickel alloys are characterized as difficult-to-weld materials; this is one of the main factors limiting their use. This paper presents the results of the development and industrial exploitation of welding technology for heat-resistant nickel alloy grade CrNi₆₂MoCh₂-VI (EC 199-VI). The quality control results of the obtained welded joints are presented. Notably, the welded joints of the CrNi₆₂MoCh₂-VI alloy exhibit resistance to intercrystalline corrosion and demonstrate improved mechanical characteristics.
