FIELD: process engineering.
SUBSTANCE: invention relates to welding and can be used for welding of long length shaped metal structures, for example, freight car sidewalls. Sidewalls are welded at the assemble bench bearing surface, the locking elements being secured at said bench. Welding hardware is displaced along the frame surface with the help of gantries in crosswise and lengthwise directions. Note here that said gantries are provided with drive motor mounted at the guides located along said frame.
EFFECT: lower production costs, higher quality of welds, decreased warpage of the walls.
