The demand on clad pipelines which are combined corrosion resistance alloy (CRA) with carbon steel has been increasing recently. Metal inert gas (MIG) welding with nickel based alloy wire is usually applied for the girth welding of stainless clad pipes. On the work-barge to lay offshore pipelines, however, it has some difficulties. To solve those assignments, FSW+ MAG welding process has been developed. In this study, several FSW conditions were examined, and sound FSW joint without dilution between stainless steel and carbon steel were obtained. Then, corrosion resistance and mechanical properties of FSW+MAG welding joints were evaluated.
