| 摘要: |
| 提出了旋转冲击控制应力变形的新方法,并研制了一套旋转冲击装置.工作时通过电锤带动装配在其上的压杆施加旋转冲击作用于焊缝及焊趾部位,使其延展产生拉伸塑性应变来抵消焊接过程产生的残余压缩塑性应变,从而有效的控制了工件的焊接变形.应用所研制的装置,对2A12T4铝合金进行控制焊接变形的试验,发现旋转冲击可以起到减小焊后工件中残余变形、细化焊缝晶粒、提高强度的作用. |

| Abstract: |
| A new technology called impactive rotating is put forward to control weld distortion,the integrated device of impactive rotating has also been designed.Driven special columned pressure pole with a electric hammer,impactive force with rotating action is exerted to the metal of the welding bead and the toe of weld.The metal stretch and generate tensile plastic strain to counteract the residual compression plastic strain,generated in the welding process,and finally the welding distortion has been reduced.The result of experiment applied the equipment for the high strength aluminum alloy indicted that this technology can decrease the weld distortion as wll as refine grain and enhance strength of joint weld metal. |
| Key words: impactive rotating electric hammer residual distortion weld |
