通过对锅炉压力容器用焊接材料的中、美、日和欧洲共86个国家标准,国内外6家著名厂商的726J焊条型号与牌号、555个焊丝型号和牌号、178个焊丝-焊剂型号与牌号进行了全面综合分析对比,总结了我国焊接材料特点,阐明我国承压设备用焊接材料技术要求,指出当前焊丝国家标准两个系统的危害,以及焊丝、埋弧焊焊材标准不保证熔敷金属化学成分与力学性能等的不足,对我国承压设备用焊材的需求及发展提出明确要求。
Through the welding materials of boiler pressure vessel in China, the United States, Japan and Europe, a total of 86 national standards, 6 well-known domestic and foreign manufacturers 726J electrode models and grades, 555 wire models and grades, 178 wire - flux type and grade Conducted a comprehensive and comprehensive analysis and comparison, summarizes the characteristics of China’s welding materials, clarify the technical requirements for welding materials used in pressure equipment in China, pointed out that the current national standard wire system two hazards, as well as wire, submerged arc welding consumable standard does not guarantee the deposited metal Chemical composition and mechanical properties of the lack of China’s pressure equipment welding consumables demand and development made clear requirements.
