| 摘 要： | 利用激光为背景光的成像系统,摄取电弧形态和熔滴过渡的高速图像,试验了新研制的屈服强度为980MPa级钢配套的两种焊丝电弧形态和熔滴过渡形式.试验在典型焊接参数条件下,采用不同配比的氩、氦混合保护气体MIG焊接方法,对所研制的焊丝与普通焊丝H08Mn2SiA进行了电弧形态和熔滴过渡对比试验.结果表明,所研制的焊丝不仅其熔敷金属力学性能满足要求,而且熔滴过渡性能也优于常用的普通焊丝,为所研制焊丝的焊接工艺性能和实际应用奠定了试验基础.

| Abstract: | Several high-speed images of arc shape and globule transfer are obtained while using laser to be the background light of the imaging system.The arc shape and globule transfer modes of two kinds of newly researched weld wire attached to the steel with the yield intensity of 980 MPa class are studied.On condition of typical welding parameters,the MIG welding method which uses different proportions of mixture of Ar and He as protecting gases is used to conduct contrastive experiments in the arc shape and globu... |
