Contact-Resistance Assessment of the Stress-Strain Condition of Welded Joints

Viktor M. Kislitsyn, Sergei A. Voronin

NDT-related diagnostics have triggered renewed popularity of the contact-resistance method indicating linear dependence between the electric resistance of metals and tensile stress having significant resistance sensitivity. The contact-resistance method enables the indication of a moment where elastic stresses transform into plastic stresses and can also be used to detect welding imperfections.
