汽车盒式梁车架焊接工艺分析和设计

Analysis and Design of Welding Technology for Automobile Box-beam Frame

盒式梁车架总成主要靠焊接连接,焊缝复杂,弧焊后变形量大,影响悬架、转向、发动机等系统的后续装配精度。为了保证车架的焊接质量,文章夹具结构、焊接顺序和焊接设备等方面提出对盒式梁汽车车架的焊接变形及质量控制方法。

The box-beam frame assembly is mainly welded,the weld seam is complex,and the deformation after arc welding is large,which affects the subsequent assembly accuracy of suspension,steering,engine and other systems.In order to ensure the welding quality of the frame,the welding deformation and quality control methods of the box-beam frame are put forward in the aspects of fixture structure,welding sequence and welding equipment.
