| Abstract: | The effect of pulse gas metal arc welding(GMAW-P) parameters on impact tonghness of welding joint nominal fusion line in TCS345 stainless steel were investigated through orthogonal experiments.The influencing factors such as pulse current,time,frequency and welding speed were considered.The result shows that the microstructure in heat affected zone(HAZ) of TCS345 stainless steel composed of ferrite and martensite.Optimization of GMAW-P process parameters was carried out by the software of MATLAB,that is,pulse current 450 A,pulse time 2.3 ms,pulse frequency 250 Hz,and welding speed 500 mm/min. |
| Keywords: | pulse gas metal arc welding parameters TCS stainless steel nominal fusion line notched impact strength |
