Abstract: A welding device and method for powder welding. The welding device includes at least a first container for fluxing agent in powder form, which first container includes an outlet with an outlet direction arranged for outflow of powder. The welding device further includes a first member for inlet of heated gas into the first container. The welding method includes arranging powder in the first container. Gas is heated and is allowed to pass into the first container for heating of the powder. The powder is then deposited on a welding area.

Abstract: A welding device for powder welding is described, which comprises a welding head for transportation of at least one welding electrode to a welding area, and a powder transportation device for transportation of powder from a container to the welding area. The powder transportation device comprises at least a first pipe which at a first end has an opening which is arranged to be placed in the container in order to transport fluxing agent from the container. The powder transportation device comprises at least a first ejector which is connected to the second end of the first pipe and which is arranged to transport powder from the container via the first pipe using pressurized gas.

Abstract: A welding device (1) for powder welding and a method for powder welding is described. The welding device comprises at least a first container (4) for fluxing agent in powder form, which first container (4) comprises an outlet (6) with an outlet direction (7) arranged for outflow of powder. The welding device (1) comprises a first member for inlet of heated gas into the first container. According to the method powder is arranged in the first container. Gas is heated and is allowed to pass into the first container (4) for heating of the powder. The powder is then fed out on a welding area (3).

Abstract: In a plant for the manufacture of welded gratings composed of longitudinal members and crossbars welded to said longitudinal members, the crossbars are removed one at a time from a store to a retaining device capable of holding two crossbars at a predetermined horizontal spacing between each other. The pair of crossbars is discharged from said retaining device on to a carrying device arranged to carry the pair of crossbars into the welding station and deposit them on the longitudinal members there while still retaining their predetermined horizontal spacing.
