摘要

针对800 MPa级高强钢焊丝，采用外加横向磁场辅助MAG焊的方法进行了熔敷金属的制备，通过高速摄像的方法观察和分析了外加横向磁场作用下的电弧形态和熔滴过渡特征，并借助OM和EBSD等方法对比分析了有无外加横向磁场作用下熔敷金属的微观组织形貌，同时测试了熔敷金属的力学性能。研究结果表明：外加横向磁场会使电弧形态和熔滴发生偏转，熔敷金属的组织晶粒平均尺寸相比无磁场时细化了9.3%，织构种类转变为｛111｝<110>，｛111｝<112>，｛110｝<112>，｛001｝<100>；与不加磁场相比，熔敷金属的抗拉强度提高了4.65%，伸长率提升了3.4%，低温冲击韧性提高了28%。

Abstract

For 800 MPa high strength steel welding wire

the deposited metal was prepared by MAG welding assisted by applied transverse magnetic field. The arc shape and droplet transition characteristics under the action of applied transverse magnetic field were observed and analyzed by high-speed camera method. The microstructure of deposited metal with or without external transverse magnetic field was analyzed by OM and EBSD

and the mechanical properties of deposited metal were tested. The results show that the addition of transverse magnetic field can deflect the arc shape and melt drop

and the average grain size of the deposited metal is refined by 9.3% compared with that without magnetic field

and the texture types change to {111}<110>

{111}<112>

{110}<112>

{001}<100>. Compared with no magnetic field

the tensile strength of the deposited metal is increased by 4.65%

the elongation is increased by 3.4%

and the low temperature impact toughness is increased by 28%.
