激光焊接技术的应用研究进展与分析

Research Review and Analysis of Laser Welding Application

激光焊接技术因具有热影响区小、质量稳定、焊接变形小、自动化程度高以及可焊接难焊材料等优点,被广泛应用于航空航天、汽车制造、船舶、石油石化、轨道交通等工业领域,并得到广泛的关注。在大量研究国内外有关激光焊接技术相关文献报道的基础上,针对近期激光加工领域中研究比较广泛的几种激光焊接技术的研究进展和应用情况进行了全面概述,主要包括激光自熔焊、激光复合焊、激光-场耦合焊、激光填丝焊、激光填粉焊以及激光双光束焊等,分析了各焊接过程的机理及相关影响因素,并着重介绍了不同激光焊接技术的应用特点和研究进展。以期为激光焊接相关从业者提供全面、翔实、可借鉴的文献参考。

Laser welding technology was widely used in aerospace,automobile manufacturing,shipbuilding,petroleum and petrochemical,rail transit and other industrial fields,and had been widely concerned,because which has the advantages include small heat affected zone,stable welding quality,small welding deformation,high degree of automation,and difficult welding materials could be welded.The application of several kinds of laser welding technology which were studied widely was summarized,which mainly includes the laser self-fusible welding,laser hybrid welding,laser-field coupling welding,laser filler wire welding,laser welding with powder feed,and dual beam laser welding,the mechanism of the welding process and the related influencing factors were analyzed.Finally,the application characteristic and and research progress of the different laser welding technology were emphatically introduced.It’s expected to provide comprehensive,detailed and referential reference for the laser welding industry practitioner.
