国外船用激光焊接波纹夹芯板的开发与应用

激光焊接波纹夹芯板（LASCOR）结构能够减轻重量，减少占据空间，降低噪音和振动，增强防火安全性和热绝缘性，改善防撞击性，通过精确预制可降低制造成本，便于快速组装，通过板和接头的模块制造，可灵活组装。采用激光焊接可减少焊接变形和提高生产率，改善焊缝耐蚀性。该结构已在舰船（甲板、舱室隔板、升降机门、机库房门、航空母舰的偏流板），海洋平台（住居舱室、平台），桥梁面板，汽车，列车和建筑等部门得到广泛的应用。文中概述了目前美欧各国LASCOR结构在海军和船舶制造工业中取得的成果，以期对我国造船工业和海军舰艇夹层结构的开发研究有所启示。

Introduction to Development and Applications of Marine Laser Welded Lightweight Sandwich Panel in the US Navy and European Countries

The laser welded lightweight sandwich panel(LASCOR)structure has many advantages,including weight saving,smaller space,lower noise and vibration,improved fireproofing,enhanced thermal insulation,improved impact resistance,lower manufacturing cost with precise prefabricating method,easy and quick assembling.Utilizing laser welding can reduce welding distortion and increase productivity,as well as improve corrosion resistance of the weld.It has widely been used for deck,bulkhead,elevator door,hangar door,and jet deflector panel in a naval ship,deckhouse and platform of an offshore platform,bridge faceplate,car,train,and construction etc.The results obtained in the US Navy and the shipbuilding industry of European countries are summarized in order to provide a reference to Chinese researchers in this field.
