Paper Title:
Residual Stresses and Distortions in Aluminum Alloy Sheet after Welding under Pre-Tension
  Abstract

By applying the elastic pre-tension method, 5A05 aluminium alloy sheets with 4mm thickness were welded. It is shown that the peak value of residual stresses and their distribution vicinity, the longitudinal buckling distortions and plane deformations of specimens after welding under pre-tension were obviously reduced. It is considered that pre-tension counteracts the compression stress in regions close to the weld generated by thermal expansion, consequently reduces the compression plastic deformations and the tensile stresses in these regions when cooling down, and accordingly diminishes the compressive stresses far from the weld.
