By being welded to connect fixation.
Further, first spandrel girder, the second spandrel girder, third spandrel girder are an integral molding structure.
Using above-mentioned technical solution, when workshop welder is when welding, it is first directed to the rectangular frame structure of vehicle frame
It is welded, then again by sequentially welding third spandrel girder, the first spandrel girder and the second spandrel girder so that the first spandrel girder exists
When being welded, the first spandrel girder need to be only lifted, then be carried out towards the end of the first spandrel girder with third spandrel girder
It is affixed welding, from both ends weld with third spandrel girder by elder generation, then the mode gradually welded toward middle part, can subtract significantly
In addition few the case where deforming upon offset in the welding process, finally carries out welding is located between a pair of first spandrel girder second
Spandrel girder so that the second spandrel girder can not only improve the integral strength of vehicle frame, additionally it is possible to by between a pair of first spandrel girder into
Line position sets positioning, and there is a situation where position deformation displacements for the second spandrel girder during preventing follow-up use.
