摘要

文章对 EP718 镍合金接头的焊接区和焊接影响区 (WAZ) 的结构和特性进行了研究。这些焊点是在氩气环境下通过机器人脉冲气体金属弧焊(GMA 焊接)和电极横向摆动获得的。与之前使用脉冲 GMA 焊接的实验相比,所研究的高温镍合金焊接接头的宏观截面显示出极其不典型的 WAZ 细粒结构,其中有局部晶粒生长区域。通过脉冲 GMA 焊接获得的厚度为 4 毫米的 EP718 合金样品焊接接头的极限抗拉强度为 1056 兆帕。厚度为 4 毫米的 EP718 合金焊接接头在 650 °C 下的短期强度达到了 949 兆帕。根据 EDXS 分析,在这些区域的边界上可分辨出 TixNy 类型的颗粒和 MxCy 类型的碳化物。这些颗粒是在温度范围为 700-1200 °C 的 WAZ 区域形成的。对 WAZ 的详细 EDXS 分析表明,钼和硫在某些部分的含量增加,铌和铁的含量同时减少,铌和钼的含量也有所增加(与初始合金相比增加了 50-70%)。

Study of the Structure and Properties of EP718 Alloy Welded Joints Produced by Robotic GMA Welding

The article presents a study of the structure and properties of the welding zone and the weld-affected zone (WAZ) of the EP718 nickel alloy joints. The joints are obtained by robotic pulsed gas metal arc welding in argon (GMA welding) with transverse oscillations of the electrode. The studied macrosections of welded joints of high-temperature nickel alloys show an extremely atypical picture of the fine-grained structure of the WAZ with local grain growth regions, comparing to previous experiments using pulsed GMA welding. The welded joints of the EP718 alloy samples of 4 mm thickness obtained by pulsed GMA welding demonstrated the ultimate tensile strength of 1056 MPa. The short-term strength of welded joints of the EP718 alloy 4 mm thickness at 650 °C reached the value of 949 MPa. According to EDXS analysis, particles of the TixNy type and carbides of the MxCy type are distinguished along the boundaries of such areas. These particles are formed in the WAZ zone in the temperature range of 700–1200 °C. A detailed EDXS analysis of WAZ revealed an increased content of molybdenum and sulfur in certain sections with a simultaneous decreased content of niobium and iron, as well as sections with increased (by 50–70% compared to the initial alloy) concentrations of niobium and molybdenum.
