The automatic control device of powder feeding for laser cladding integrates the special Z-type measuring path and the sensor into the powder feeder of scraper type. According to the powder flux variation and the program's request, it fulfils the aim to adjust the powder flux automatically by controlling the gap between the powder-mouth and dial or by controlling the rotational speed of the dial, with the help of examining the powder flow signals in the path and analyzing the examined signals.
