    摘要
  • 摘要: 在第70届国际焊接学会（International Institute of Welding，简称IIW）年会上，电弧焊与填充金属委员会（Commission II-arc welding and filler metals,简称C-II）共收录论文30篇，内容涉及焊缝金属冶金、焊缝金属测试与测量及焊缝金属的分类与标准化等三个主题。焊缝金属冶金主题收到论文11篇，内容涉及焊缝金属中的氢、焊缝金属组织结构、焊接裂纹及高强钢焊接材料等多个方面。焊缝金属测试与测量主题收录论文11篇，内容涉及镍基合金、高强钢和耐热钢等。焊缝金属的分类与标准化领域收到8篇论文，主要涉及扩散氢测量、焊缝金属成分分析等相关内容。

     

    Abstract: In the 70thInternational Institute of Welding（IIW） Annual Assembly and International Conference,the total of 30 papers were accepted by commission II-Arc Welding and Filler Metals（C-II）. The contents of these papers involve three topics,covering the metallurgy of weld metal,testing and measurement of weld metal,and classification and standardization of welding consumables. Among these papers,the topics of 11 papers are about the metallurgy of weld metal,covering hydrogen in weld metal,microstructure and constitution of weld metal,weld metal cracking,and filler metals for high-strength steel. The topics of another 11 papers are related to testing and measurement of weld metal,covering the nickel-base alloys,high-strength steels,and creep and heat resistant steels. Moreover,the last 8 papers concern the classification and standardization of welding consumables,which mainly involve the diffusible hydrogen testing,chemical compositions analysis of weld metal and so on.
