Vehicle cab incorporating a cab frame (4) with a welded roof structure (6). The roof structure comprises partly a roof middle section (26) and partly a pair of roof side sections (28) which are welded to opposite edge portions of the roof middle section (26). The welded connections between the roof middle section and the roof side sections from sheet metal flange joints between sheet metal flanges (26', 28') (which are connected to one another and are directed outwards) of the roof middle section and the respective adjacent roof side sections. The invention also concerns a method of erecting and assembling the aforesaid type of vehicle cab. The roof middle section (26) is first positioned on top of the frame (4) and is welded in a front edge region (36) and in a rear edge region (38). Necessary supplementary welding of the cab frame can be done via the still incomplete roof areas and only thereafter are a pair of roof side sections (28) welded to opposite sides of the roof middle section (26).
