Embodiment Construction
[0026] Preferred embodiments of the present invention will be described in detail below.
[0027] The reference signs in the accompanying drawings of the specification include:
[0028] Air duct support 1, bent plate 2, automobile beam 3, fillet weld 4, butt weld 5.
[0029] A lightweight aluminum alloy automobile roof welding process, comprising the following steps:
[0030] A. Preparation before welding: pass the car roof air duct bracket through such as Figure 1~2 The extrusion die shown is integrally extruded, and the air duct support is cut equidistantly after the integral extrusion. The cross-section of the extrusion die is the same as the end surface structure formed by two L-shaped angle aluminum tailor-welded on the upper and lower sides of the longitudinal beam. ;
[0031] B. Formal assembly: clamp the air duct support 1, automobile beam 3 and bending plate 2 after equidistant cutting on the welding tool (such as Figure 3-6 As shown), the reverse deformation is...
