| Abstract: | The welded joint strength of thin-skinned pressure vessel acts as critical factor of its pressure proof. To study technics of welding and heat treatment for ensuring strength of welded joint in it, 6061 aluminum alloy plates were welded by TIG. And then heat treatment is applied to the plates with "solution treatment + artificial aging". Tensile tests were used to verify the strength of welded joint. Feasible parameters of TIG and heat treatment were confirmed by the tests. The cause of weld defect and the countermeasure are mentioned in this paper. |
