摘要
讲述采用埋弧横焊方式焊接船体CM(Construction Monitoring)节点。使用不同直径的埋弧焊丝进行试验,从工艺性能及力学性能方面进行讨论。结果表明,采用Φ4.0mm的焊丝进行埋弧焊,工艺性能较好,力学性能亦能满足船级社LR和DNV规范要求。将埋弧焊方法与传统半自动CO2气体保护焊焊接方法进行应用对比得知,埋弧焊能够有效提高焊接质量及综合工作效率。
The Submerge Arc Welding（SAW）on CM node is described.The test of SAW with different diameters is carried out,and the technological and mechanical properties are discussed.The results show that the SAW with the diameter of 4.0 mm not only gets good processing properties but also meets the mechanical properties requirement of classification society LR and DNV.The SAW procedure is compared with FCAW procedure,which shows that the SAW procedure can improve the welding quality and working efficiency.
