摘　　要：T形构件角焊缝在船舶行业极为常见,随着结构强度要求的提升,T形构件及被焊件厚度亦逐渐加大。MAG焊作为船舶行业使用效率最多的高效焊接方式,具有改善焊缝熔深形状及外观成形、控制焊缝冶金质量,减少焊接缺陷、降低焊接施工成本等特点。针对非垂向安装的船舶用高强钢厚板T形构件角焊缝MAG焊接,基于Simufact Welding焊接仿真软件建立贴合实际焊接情景的有限元仿真模型,对其焊接过程的温度场和应力应变场进行研究分析,为实际生产提供理论依据支撑。Fillet welds of T-shaped components are very common in the shipbuilding industry,and with the upgrade of structural strength requirements,the thickness of Tshaped components and welded parts is increased accordingly.MAG welding,as the most efficient welding method in the shipbuilding industry,has the characteristics of improving the penetration shape and appearance of the weld,controlling the metallurgical quality of the weld,reducing welding defects and lowering welding costs.For MAG welding of fillet welds of non-vertically-mounted highstrength steel thick-plate T-shaped components of ships,a finite element simulation model that fits the actual welding scenario is established based on Simufact Welding simulation software,and the temperature field and stress-strain field during welding are studied and analyzed to provide a theoretical basis for practical production.
