本文综述国内外焊接材料品种结构的演变和焊接冶金问题研究深化的概况。针对冶金企业提出三条建议:(1)加强焊接冶金问题的研究以大力发展易焊结构钢材;(2)重视焊接材料(主要是各种焊丝)品种、质量和数量的开发生产;(3)注意组织协调钢厂、焊接对料生产厂和钢结构制造厂及施工单位的科技力量,共同开发重大工程(如海洋平台、管线、锅炉、压力容器、工程结构、船舰和重型钢轨等)用的各种易焊结构钢材、焊接材料和焊接工艺。
This article summarizes the evolution of welding material variety structure both at home and abroad and the general situation of deepening research on welding metallurgy. For the metallurgical enterprises made three recommendations: (1) to strengthen the study of welding metallurgy to develop easily welded steel structure; (2) emphasis on welding materials (mainly a variety of welding wire) varieties, quality and quantity of development and production; (3) attention Organize and coordinate the scientific and technical strength of steel mills, welding materials manufacturing plants, steel structure manufacturing plants and construction units to jointly develop major projects such as offshore platforms, pipelines, boilers, pressure vessels, engineering structures, ships and heavy rails, etc. A variety of easily welded structural steel, welding materials and welding processes.
