| 中文摘要: |
| 针对目前不锈钢薄板在焊接时，存在的焊接结构件变形、焊接质量差、使用性能低等缺点，为进一步改善薄板焊
接加工工艺，对焊接变形影响因素进行分析，重点从输入热源、焊缝尺寸、初始粗糙度、板厚和焊接装配等因素出发阐述
了对焊接变形的影响。提出在焊接时需要通过进一步畸化焊接温度场、增强焊接结构件刚度、设计施加辅助热源或冷
源、夹具约束或者旋转挤压等组合装置来达到控制薄板的挠曲变形的目的。最后提出有限元仿真技术在焊接中的应用
将会更加科学地分析和预测焊接变形。 |

| At present. there are shortcomings of welded structure deformation, poor welding quality and low performance in the welding of stainless steel sheet. In order to further improve sheet metal welding process. welding deformation factors were reviewed in the article. After a brief introduction of common plate deformation, the impact of welding deformation from input heat, weld size. initial roughness,described. And further distortion of welding temperature thickness, welding assembly and other factors were focus field or enhancement of welding structure stiffness were presented in the article. an auxiliary source of heat or cold. fixtures constraints. the device of rotating extrusion were designed to reach sheet deflection control purpose. The article notes that the application of finite element simulation technology in the welding will more scientifically analyze and predict welding deformation. |
