Because nozzle shape with oblique cut models is asymmetric, the disturbance produced at the exit of nozzle is reflected on the longer side and causes shock waves in the inner flow.
The results show that the stable and reliable shielding gas can be obtained with a simple gas cooling TIG gun when it possesses oblique holes on the nozzle device.
