Powder Feeder

The gravity laser cladding powder feeder is a key device in laser cladding technology that is suitable for the off-axis powder feeding process. It relies on the weight of the powder itself to complete the transportation and does not require or only requires a small amount of auxiliary gas. It has significant advantages in improving powder utilization and reducing costs. This equipment is a laser cladding accessory device that conveys alloy powder to the cladding area of the workpiece by its own gravity and is often used in conjunction with the off-axis powder feeding cladding process. During operation, the alloy powder in the powder storage structure is directionally conveyed to the surface of the workpiece through the preset powder distribution and feeding channels under the action of gravity to complete the powder spreading. Subsequently, the laser beam scans the preset powder and melts it to form a cladding layer. Some advanced models are equipped with structures such as scrapers and turntables to regulate flow, or have auxiliary gas channels to prevent minor blockages, but their core power remains gravity.
