6) double-wire MIG welding
双丝MIG焊接
1.
Because the heat input quantity during double-wire MIG welding thick plates was great,the welded joint was in the high temperature state for a long period of time and the former solidified metal experienced an "involuntary" aging treatment,which mean that the weld metal had reached the "peak aging" or sub-"peak aging" already.
试验发现20 mm厚2519铝合金双丝MIG焊接接头存在时效弱化问题,这是由于厚板双丝MIG焊热输入量大,接头长时间处于高温状态,已凝固焊缝金属相当于已经接受了一次时效处理,接头在焊后已经达到“峰失效”或接近“峰失效”的欠时效状态。
补充资料:Mig-27战斗机
米格-27是米高扬设计局在米格-23c基础上研制的战斗轰炸机。原称米格-23б,后改称米格-27。1969年完成设计,1970年8月20日首飞,1971年开始批生产,至80年代后期停产时共生产了1000多架,其中1973年改称米格-27以后的各型就有910多架。
值得留意的是上图这架机所属部队是“近卫军”部队,进气口旁有红旗麦穗“近卫军”徽章。“近卫军”是苏联授予表现突出、功勋卓绝的部队的光荣称号。
该机外观上与米格-23相似,但是机头取消了大型对空火控雷达,改为对地光电装置,机头变小并下倾,增大背脊面积,重要部位增加了装甲。由于对地攻击对机动性要求不高,米格-27换装了简化的进气口和喷口。这使得米格-27的超音速性能与米格-23相比有下降,但简化了结构,降低了成本。米格-27采用一台图曼斯基r-29-3000发动机,推力11500千克。固定武器为一门23mm gsh-30-6(9a621)加特林机炮,外挂载重量4吨。图中米格-27正在降落,打开了尾部减速伞,并且放下了前缘襟翼。
