Gas and Powder Flow Optimization in a Four-Jet Laser Cladding Head
- 41 Downloads
Gas and powder flow structure in a four-jet nozzle of a laser cladding head was optimized using a shadow imaging device and high-speed tracer visualization. Experimental results show that an excessive protective gas flow rate can lead to the spatial defocusing of transport gas jets.
