摘要
在电子束焊接试验的基础上,研究了真空电子束焊接2A12时焊缝接头的力学性能;探讨了电子束焊接2A12时,影响焊缝强度的主要因素是在焊接过程中产生的气孔缺陷,同时分析了2A12铝合金焊缝气孔产生的倾向和表面焊前清理、焊接参数、预热以及重熔方法之间的关系。结果表明,在采取一定的焊接工艺措施后,接头中的气孔缺陷可得到很好地控制,保证了焊缝所需的力学性能,满足设计使用要求。
Based on the electron beam welding tests of 2A12 aluminum alloy,it describes the mechanics performance of welded joint about the vacuum electron-beam welding 2A12. It describes the primary factor of the influence about welded intensity of welding 2A12 is the pore flaw which is produced in the welding process ,and it analyzes the relationship between the generation of pore in welding zone and the cleaning of su（face before welding,welding process parameter,preheating and remelting.The result indicates that after taking certain welding technology measure ,the pore flaw has been controlled well,and we have achieved the mechanics performance and satisfied the design requirements.
