POWDER CONVEYING SYSTEM FOR A LASER POWDER BUILD-UP WELDING APPARATUS

摘要

An improved powder feed device (1) for a laser build-up welding apparatus is introduced. The powder feed device has a first powder reservoir (2), a second powder reservoir (3), a first powder conveying apparatus (4) and a second powder conveying apparatus (5). The first powder conveying apparatus (4) is configured to transport a powder from the first powder reservoir (2) into the second powder reservoir (3). The second powder conveying apparatus (5) is configured to transport the powder from the second powder reservoir (3) to a transfer location (6).
