Transfer behaviors of carbon and manganese of flux-cored wire in gas shielded arc welding

In this paper,the transfer behaviors of carbon and manganese of flux cored wire in gas shielded arc welding were studied.The experimental results show that the element Mn was the lose regardless of CO₂ or Ar+20%CO₂ shielding gas and as the oxidizability of the arc or the wire increases the lose aggravates.Therefore,by decreasing the oxidizability of the arc or the wire Mn lose can effectively decrease.For the element C,as the oxidizability of the wire increases the transfer changed from increase to lose and as the oxidizability of the arc increases the transfer increase occurs more easily.Therefore,by decreasing the oxidizability of the arc and by increasing oxidizability of the wire,the transfer increase can be restrained.
