| Abstract: | Aiming at the welding performance of dissimilar steel between the compositions of pillow beam(560W carbon steel)and longitudinal beam(301LN stainless steel)at the bottom end of an urban rail transit vehicle,according to the relevant data and standards,the gas metal arc welding(GMAW)method is adopted and ER309LS1 welding wire is used for a welding process test.The welding process performance between 550w and 301LN dissimilar steels is verified by means of flaw detection,mechanical properties,observation of low power weld microstructure and hardness testing.Results show that the tensile and bending properties of the samples are good and can meet the requirements of relevant standards.The weld joint is also qualified,the weld penetration and fusion quality both meet the standard requirements.Thus,the feasibility of the dissimilar steel welding process between 560W carbon steel and 301LN stainless steel are determined. |
