Abstract

A welding device (1) for powder welding is described, which comprises a welding head (2) for transportation of at least one welding electrode (3) to a welding area (4), and a powder transportation device (5) for transportation of powder from a container (6) to the welding area (4). The powder transportation device (5) comprises at least a first pipe (8) which at a first end has an opening (9) which is arranged to be placed in the container (6) in order to transport fluxing agent from the container (6). The powder transportation device (5) comprises at least a first ejector (7) which is connected to the second end of the first pipe (8) and which is arranged to transport powder from the container (6) via the first pipe (8) using pressurized gas.

Description

technical field [0001] The present invention relates to a device and a method for processing powder for welding equipment for powder welding. More specifically, the present invention relates to an apparatus and method for conveying powder from a container to a welding area in powder welding. Background technique [0002] The present invention relates to powder welding, which is a well-known welding technique in which a flux mixture in powder state is applied to a surface and then welded. At least one electrode is moved over the powder-coated surface and a voltage is applied between the at least one electrode and the surface. It is best to weld after the entire welding area has been piled up with powder. [0003] Currently, welding equipment for powder welding is suitable for welding at very high speeds, consuming a large amount of powder per unit time. Existing welding equipment includes at least one powder container in which new powder is mixed with old powder not consum...
