简介:WeldingresearchofA6N01S-T5aluminumalloyprofileforhigh-speedtrainwasdonebyusinglaser-MIGhybridweldingandMIGweldingindividually.Andtheweldappearance,weldingdistortion,mechanicalpropertiesofthejointsandmicrostructureswereanalyzed.Thetestresultsdemonstratedthathigh-efficientweldingfortheprofilecanbeachievedbyusinglaser-MIGhybridwelding,thespeedofwhichcanbeover3.0m/min.Theprocessinghadagoodgapbridgingability,evenifthegapofthebuttjointwasupto2.0mm,agoodweldappearancecanalsobegot.Whilethehybridweldingspeedwasgreaterthan2.5m/min,theweldingdistortionofthelaser-tandemMIGhybridjointswasjustabout33%ofthatoftheMIGjoints,buttheweldingefficiencywasover3timesofMIGwelding.Andtensilestrengthofthehybridjointswas85%ofthatofA6N01S-T5basemetal,9%higherthanthatoftheMIGjoints.Fatiguepropertieswastestedindividuallywithpulsedtensilefatiguemethodintheconditionof1×107lifetime.Thetestresultsdemonstratedthatthefatiguestrengthofthejointswasalittlelowerthanthatofbasematerial,whichcouldbeupto115MPa.Butthefatiguestrengthofhybridweldingjointswas107.5MPa,whichwas23%higherthan87MPaofMIGweldingjoints.
简介:这份报纸在海洋动力学介绍吸收技术当模特儿并且讨论转换的可行性在由吸收单个车站HF检测的光线的速度扎根了的海水流的察觉地区的海表面水流在海洋动力学的波浪雷达模型。基于伴随吸收和POM模型,纸成功地转换通过单个车站HF的海表面水流磨擦了在Zhoushan海的波浪雷达区域。单个车站HF雷达倒置结果也与bistatic相比合成结果和固定的点测量了的HF雷达由Annderaa电流结果米。错误分析证明从单个车站HF雷达的速度和流动方向数据基于伴随吸收和POM建模的流动的获得是可行的,数据获得有高度与流动域的关联和一致性由HF观察了雷达。
