This paper was to study the solidification crack generation of a root pass in one side FCAW process on the SPPV490 is a high strength pressure vessel steel on the 590MPa class and SWS400 is a welding structure steel. A main parameters of it were welding materials and welding conditions. For the purpose of it, a shape coefficiency and linear regression analysis were used. And then the crack generation rate was discussed to the SPPV490 and SWS400.
