摘要 |
A build-up spraying apparatus is disclosed which is capable of positionally adjusting the spreading rate of build-up metal powder on an article along the spreading direction to satisfactorily carry out partial or local build-up as well as uniform build-up as desired. The build-up spraying apparatus includes a fluid control device for spreading build-up metal powder having a pair of control gas injection nozzles formed at the both sides of the interior thereof and a control gas switching cycle setting means for supplying two systems of control gas to the fluid control device at a predetermined cycle to positionally control the spreading rate of build-up metal powder in the spreading direction. The apparatus also includes at least one heating burner body for heating build-up metal powder ejected from the fluid control device, the heating burner body being adapted to vary the amount of heat according to the difference in injection rate of build-up metal powder in the spreading direction. |
