Embodiment Construction

[0019] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0020] refer to Figure 1-3 As shown, the embodiment of the present invention provides a welding method for a vehicle frame longitudinal beam, comprising the following steps:

[0021] S11 , defining a plurality of welding positions 40 on one side of the preset separation line 30 of the longitudinal beam inner panel segment 10 and the longitudinal beam outer panel segment 20 .

[0022] Such as figure 2 As shown, these welding positions 40 are distributed on the side of the preset separation line 30 of the longitudinal beam inner panel segment 10 and the longitudinal beam outer panel segment 20 , and are staggered from each other.

[0023] S12. By welding multiple welding positions 40, the longitudinal beam inner plate segment 10 and ...

Abstract

The invention provides a frame side-rail welding method used for solving the problem of high possibility of deformation of a frame side rail in the conventional frame side-rail welding method. The welding method comprises the steps as follows: defining a plurality of welding positions on one side of a preset partition line of a side-rail inner plate section and a side-rail outer plate section; and welding the side-rail inner plate section and the side-rail outer plate section by welding the welding positions to form a frame side-rail section, wherein the welding positions are welded in sequence from the preset partition line of the side-rail inner plate section to a free end and each pair of the welding positions are welded in the direction from the free end to the preset partition line. According to the welding method, the Z-direction deformation difference of the frame side rail is minimized, so that the frame side rail cannot be easily deformed.

Description

technical field [0001] The invention relates to the technical field of longitudinal beam welding, in particular to a welding method for vehicle frame longitudinal beams. Background technique [0002] The automobile frame is not only the main body of the connection of various parts on the chassis, but also the reference part and important connecting part when the body and chassis are assembled, which requires a very high overall manufacturing precision of the frame to ensure that each part and its related parts Match accurately. The existing frame longitudinal beam is usually welded by the combination of the longitudinal beam inner plate and the longitudinal beam outer plate. When the operator welds the longitudinal beam inner plate and the longitudinal beam outer plate, the welding seam is very long, which may easily cause the frame longitudinal beam out of shape. Contents of the invention [0003] An embodiment of the present invention provides a welding method for a ve...
