Abstract
To figure out the weldability and welded joint performance on the FCAW of SM490TMC 120mm, several specimens were manufactured and 10 kinds of experiments were implemented. The result of the weld zone chemical composition test, weld metal tensile test, weld zone tensile test, and weld zone impact test has satisfied the KS. Especially, the weld zone tensile test result shows the base metal fracture, which means the weld zone performs enough required performance. In addition, the results of the weld zone bending test, hardness test, macroscopic test, microscopic test, and the maximum hardness in HAZ were showing that the FCAW weld zone has fine quality.
