The embodiment of the invention provides a vehicle frame, a welding joint structure of the vehicle frame and a manufacturing method. The welding joint structure comprises an aluminum extrusion type joint and a casting joint, and a welding gap, a welding groove and a reinforcing ring are arranged at the butt joint position of the aluminum extrusion type joint and the casting joint. In the welding process, welding flux can be completely filled in a welding gap and a welding groove to form a full welding seam, large welding current heat input can be borne, the defects of through welding or undercut and the like can be avoided, a large-range effective penetration depth can be obtained after welding is completed, and the overall structural strength is improved.

    本申请实施例提供一种车架、其焊接接头结构与制造方法。焊接接头结构包括铝挤型接头和铸造接头,在两者对接的位置处具有焊接间隙、焊接坡口以及加强环。在焊接时,使焊料可以完全填充在焊接间隙和焊接坡口内,形成饱满的焊缝,并且可以承受较大焊接电流热输入,除了可规避焊透或咬边等缺陷的产生外,在焊接完成后,还可以获得大范围的有效熔深,使整体的结构强度获得提升。
