I - DESIGN OF THE STRUCTURAL COMPONENT The special feature of this type of part is that it combines the functions of front section and rear section of the front side member and that it is made of two different kinds of panels of different thicknesses assembled by laser butt welding. II - AREA TO BE CUT FOR PARTIAL REPLACEMENT 1 - Cut 1: This line shows the centre of the area in which it is possible to carry out a partial replacement. This operation allows you to access the inside of the hollow section of the structural element to straighten it.
In this case, the side member weld line must be staggered from that of its closure panel. 2 - Cut 2: The cut is made along the butt weld. III - ASSEMBLY METHOD FOR A PARTIAL REPLACEMENT Only the connections which are specific to the partial replacement by cutting are indicated.
If there are other issues regarding access to mating faces, the various replacement options are described in the basic instructions for structural bodywork repair (see MR 400). Lines (3) and (4) on the diagram show a butt weld by continuous EGW welding. Weld (4) along the butt weld line. |
