UNS N10003高温合金的焊接工艺及质量控制
|
摘要
针对哈氏合金UNS N10003材料的特点,分析了该材料的焊接工艺性能,通过制定合理的焊接工艺及焊接质量控制措施,解决了UNS N10003材料焊接过程中易出现的热裂纹、层道间未熔合、未焊透、气孔等焊接缺陷问题。根据技术条件和图样的要求进行了焊接工艺评定,经过严格的无损及力学性能检测,结果合格,满足了业主对TMSR钍基熔盐堆核能系统中核心设备SF0主容器及堆芯构件的焊接要求。
The welding technological properties of Hastelloy UNS N10003 was analyzed based on its' characteristics. The welding defects usually produced in the welding of UNS N10003 such as hot crack, interlayer incomplete fusion, incomplete penetration, pores and so on was solved by making reasonable measures of welding procedure and quality control. The welding procedure qualification was performed base on the technical condition and requirement of the drawing.Strict nondestructive and mechanical performance tests were carried out. The results are qualified, which meets the owner's welding requirements for core equipment SF0 main vessel and core structure in TMSR nuclear energy system.
