The role of residual stress to hardening and cracking on quenched and tempered ARMOR steel welded joints
The welded joint always leaves residual stress when welding is complete; this stress produces distortion and reduces the distance between of microstructures in the joint. The purpose of this study was to observe the pattern of residual stress before and after welding of Q900&T125 Steel and Q900&T175 Steel. The material used in this study is Hot Rolled Plate Steel 10 mm thick. The material cut into two parts. Both are heated at 900° C, held for 30 minutes, and cooled in water.
