导管是航空飞机上最关键的组成部件之一。目前,国内航空飞机导管制造的焊接方式主要采用手工钨极氩弧焊,铝合金导管数量大、形状复杂多变、壁厚薄的特点致使焊接工作强度大,质量不稳定,为了满足导管数字化制造的需求,解决铝合金导管焊接变形这一难题具有重要的意义。
Catheters are one of the most critical components on an aircraft. At present, the welding methods used in the manufacturing of domestic aviation aircraft ducts are mainly made by manual TIG welding. The number of aluminum alloy ducts is large, the shape is complicated and changeable, and the thin wall thickness results in large welding work intensity and unstable quality. In order to meet the needs of catheter digital manufacture Demand, solve the problem of aluminum alloy pipe welding deformation is of great significance.
