摘要:
為了解決金屬殼體空間曲線焊縫變形,導致吊掛結構下塌、殼體形狀精度超差等問題,從空間曲線焊縫焊接變形的角度出發,分析變形產生的原因,制定變形控制措施。分析認為影響變形的因素主要有吊掛結構非對稱、固體發動機金屬殼體薄壁弱剛性等結構因素和焊接順序、焊接熱輸入量等工藝因素。并通過經驗總結、數值模擬、工藝試驗等手段,確定了預留抬高量、使用剛性工裝、優化焊接順序、采用TIP TIG焊接等控制措施。經過試驗驗證,上述措施可有效減小空間曲線焊縫焊接變形。
Abstract:
In order to solve the problems that the metal shell with space curve weld is prone to the suspended structure collapse and the shape accuracy which is out of tolerance,the causes of deformation are analyzed and the deformation control measures are developed from the perspective of the welding deformation of space curve weld. The analysis shows that the main influencing factors of deformation are the asymmetry of suspended structure,the thin-wall and the weak rigidity of the solid engine metal shell,the welding sequence,the welding heat input and other technological factors. Through the experience summary,numerical simulation and process test,the control measures such as reserved height,rigid tooling,welding sequence optimization and TIP TIG welding are determined. The experimental results show that the measures above can effectively reduce the deformation of space curve weld.
