The dependence of local deformations and internal stress fields on welding technique for grade VSt3sp structural steel: I. The influence of welding technique on the mechanical characteristics and acoustic emission parameters of grade VSt3sp steel

Abstract

A staging analysis was carried out for deformation curves and the evolution of local deformation fields in defective and defect-free specimens of welded joints of grade VSt3sp steel that were made using manual arc and manual pulsed arc welding. Stages of elasticity, microplasticity, nucleation and motion of Chernov–Luder’s bands, and parabolic deformation strengthening were considered. The parameters of acoustic-emission signals during tension of specimens with a welded seam were analyzed.
