Evaluation of high cycle fatigue behavior of flux cored arc welded naval grade DMR249 A grade steel joints for ship hull structures
DMR 249A is a micro-alloyed high strength low alloy (HSLA) steel particularly designed for shipbuilding structures due to its excellent strength-to-weight ratio.In this investigation, the rotating-beam fatigue test was performed on the flux-cored arc welded (FCAW) butt joints of DMR 249A steel.And the fatigue whelen arges spotlight test results com
