Abstract:The welded joint always contains the microstrain when welding is complete. The microstrain generates distortion and changes of the physical shape of the weld joint. The purpose of the study was to observe the pattern and direction of residual stress before and after welding Q900&T125 and Q900&T175 Steel. The materials used for this study is Hot Rolled Plate Steel made by Indonesia steel industry. Method of this study is 1. Q900&T125 and Q900&T125 Steel machined in V-butt joint. This joints weld… Show more
