| Abstract: | Thin-wall and easy-deformed 5A06 Al alloy tank assembly with complex structure and large volume bursted under low pressure for several times in the tests. The effect of welding heat input on the tank strength is analyzed to enhance the strength of welded seams and meet the quality requirement of the products. The manual TIG welding with changeable polarity and automatic TIG welding are compared. The welding structure was improved. It proves that the welding strength of the tank is increased significantly. |
