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.

A welding device according to claim 2, wherein the first set of pipes for heated gas is arranged at the outlet of the first container. 4. A welding device according to claim 2, wherein the second set of pipes is in contact with the powder in the second container. 5. A welding device according to claim 4, wherein the second set of pipes for heated gas is arranged at the outlet of the second container. 6. A welding device according to claim 1, wherein the separating wall is movable so that a volume of the first container and a volume of the second container are variable. 7. A welding device according to claim 1, wherein the size of the outlets for at least one of the first container and the second container can be varied to vary the relationship between used powder and unused powder on the welding area. 8. A welding device according to claim 1, comprising a collection device which is arranged to collect unused powder from the welding area and return it to the second container. 9. A welding device according to claim 2, comprising a heating source for providing the heated gas to at least one of: the first plurality of pipes, and the second plurality of pipes. 10. A welding device for powder welding, comprising a welding head for feeding of at least one welding electrode to a welding area, at least a first container for fluxing agent in powder form, and a powder transport device for transport of powder from an outlet of the first container to the welding area, the welding device further comprising a first member for inlet of heated gas into the first container, the first member including a first plurality of pipes transporting the heated gas into the first container and each arranged with a length axis oriented substantially perpendicular to the outlet direction of the first container, a second container for fluxing agent in powder form, wherein the first container is arranged for unused powder and the second container is arranged for used powder and wherein the powder transport device is arranged for transport of powder also from an outlet of the second container to the welding area, a second member for inlet of heated gas into the second container, the second member including a second plurality of pipes each transporting the heated gas into the second container and arranged with a length axis oriented substantially perpendicular to the outlet direction of the second container, wherein the outlet of the second container ends in at least one mixing chamber in a mixing device, and wherein the second member for inlet of heated gas is arranged for inlet of gas into the second chamber via at least one of said at least one mixing chamber and via the outlet of the second container, and wherein the first plurality of pipes of the first member includes a first plurality of holes formed through one or more sidewalls for inlet of heated gas into the first container, each of the first plurality of holes having an outlet direction arranged substantially perpendicular to the outlet direction of the first container and substantially perpendicular to the length axis of the first plurality of pipes, and the second plurality of pipes of the second member includes a second plurality of holes formed through one or more sidewalls for inlet of heated gas into the second container, each of the second plurality of holes having an outlet direction arranged substantially perpendicular to the outlet direction of the second container and substantially perpendicular to the length axis of the second plurality of pipes. 11. A welding device according to claim 10, the first plurality of pipes is exposed to an interior of the first container. 12. A welding device according to claim 11, wherein the first plurality of pipes for heated gas is arranged at the outlet of the first container. 13. A welding device according to claim 11, wherein the second plurality of pipes is exposed to an interior of the second container. 14. A welding device according to claim 13, wherein the second plurality of pipes for heated gas is arranged at the outlet of the second container. 15. A welding device according to claim 10, wherein the separating wall is movable so that a volume of the first container and a volume of the second container are variable. 16. A welding device according to claim 10, wherein the size of the outlets for at least one of the first container and the second container can be varied to vary the relationship between used powder and unused powder on the welding area. 17.
