【摘要】 对SM600B无缝药芯焊兰在日本进口NK-HLTEN62U高强度钢上的应用情况作了介绍。通过试验及在大型水轮机座环上的试验表明,该药芯焊丝在技术性和经济性方面均优于日本进口的LB62和LB62UL焊条。更多还原

【Abstract】 The paper introduces that with SM 600B flux cored wire the FCAW process is applied to weld NK-HLTEN62U steel. The results show that the process with such flux cored wire possesses the better technical and economical features than the process of SMAW has with LB62 and LB62UL Coated electrodes made of Japan. The conclusion above is further demonstrated through the experiments in lab. and application in welding for bottom ring of hydro-turblne.更多还原
