Study of the Contact Thermal Compression Behavior of Copper using Scanning Contact Potentiometry Method and Finite Element Analysis

The issue of tracking residual stresses initiation in welding copper under various affected conditions is essential increasing safety through improving the quality particular, nuclear industry. This study investigated behavior welded numerically and experimentally contact-heating compression test with constant clamping force. scanning contact potentiometry (SCP) method was used to track development within weld zone. Furthermore, finite element analysis (FEA) simulate effect thermal variations, a compressive force, on mechanical factors that contribute formation Additionally, electron microscope (SEM) energy-dispersive X-ray spectroscopy (EDS) were get further information about topography composition specimen's surface. SCP results show stress initiated from volume after 200 °C, oxidation, its began surface 250 °C. Using relationship between maximum values linearized von Mises ADS at high SLS = 4.523, it found generation 150 °C zone, linearly increase temperature due expansion, which associated variation values. Comparison potentiograms 300 FEA have shown distribution stress, normal total deformation are matching those localized zone.
