摘要
工艺焊接性试验结果分析表明,在进口NiSB-162-200纯镍焊缝区存在气孔和显微裂纹,接头熔合线附近有方向性很强的晶粒长大倾向。在此基础上进行了焊接工艺评定,制定了碱蒸发器的焊接工艺规程,产品获得了满意的焊接质量。
The process weldability testing result indicates that the pores anti the metallographic micro-crack are present in the welding zone of pure imported nickel metal NiSB-162-200,and the very obvious tendency of grain growing up exists adjacent to the welding joint fusion line.Based on the analysis.the welding procedure qualification is performed and the welding procedure. specification on the alkali evaporator is established.The satisfactory welding quality of the product is acquired.
