Welding distortion control of thin Al alloy plate by static thermal tensioning

Shaoqing GUO , Xiaohong LI , Wenli XU , Xuesong LIU , Xin WAN , Xitang TIAN

The mechanism and effectiveness of welding distortion mitigation by static thermal tensioning were investigated by both finite element analysis and experiments. It shows that preset thermal tensioning can reduce longitudinal plastic compression remained in the weld and its adjacent zone significantl...

金属学报(英文版)

To investigate fatigue crack initiation characteristics of Al-Zn-Mg alloy welded joint, notched specimens were used in fatigue test for the base metal, welding bead and heat affected zone (HAZ). The fatigue fracture surface near the fatigue crack initiation site was observed by scanning electron mic...
