Experimental Analysis of Nozzle Structure on Laser Cutting Section Characteristics
In order to further improve the quality of 304 stainless steel laser processing,a laser cutting test bench was set up to carry out auxiliary gas cutting tests,and the influence of different auxiliary gas pressures on the end surface roughness and slag area was investigated.The results show that the improved nozzle structure can form a higher flow rate in the slit,enhance the bunching,improve the cutting ability,the slag area can be significantly reduced,and the roughness of the cutting section is slightly increased.At 0.6 MPa,the roughness of the second section of the improved nozzle is increased by 3.29％and the slag area is reduced by 15.4％.
