对不同厚度的5A06铝合金桁条焊后角变形进行了测量,并对其角变形变化规律进行了分析和总结,找出了影响桁条焊接角变形变化的关键因素,建立了桁条组件参数与焊前预置夹角关系数据库,用于指导实际工程生产。结果表明,桁条组件参数与焊前预置夹角关系数据库可有效指导桁条的加工和桁条组件的焊接。
After welding, the deformation of 5A06 aluminum alloy beams with different thicknesses was measured. The deformation and deformation of 5A06 aluminum alloy bars were analyzed and summarized. The key factors affecting the deformation of the welding angles of the stringers were found. Pre-weld angle preset relationship database, used to guide the actual production. The results show that the relation between the parameters of the stringer assembly and the pre-welding preset angle can effectively guide the processing of the stringer and the welding of the stringer assembly.
