Vickers Hardness Variation on the Part and Welding Cord Subjected to Plastic Deformation

By performing Vickers identifications in the area of weld bead and areas adjacent to it, degree plastic deformation can be assessed, highlighting different hardness case welding base material. During this work, welded specimens were made central with a double V-shaped cord. One was loading until breaking, noting that rupture occurred an further away from area. Another 13 required at varying degrees deformation. Stresses above elastic limit create differences those its vicinity. Due fact material have characteristics, much more pronounced deformations occur compared bead. It found suffered significantly greater than Significant relative
