| 当镍及镍基合金板材厚度小于l mm时，在焊接过程中容易出现烧穿、气孔和裂纹等缺陷，严重影响了焊接成形
质量。针对超薄镍及镍基合金的特殊性以及在焊接过程中易出现的问题，采用脉冲微束等离子弧方法焊接0.1 mm厚薄
镍板。文中分析了在一定占空比下，不同脉冲频率和不同基脉比对超薄N6镍板的焊缝成形质量的影响，得到合适的焊
接工艺参数。研究结果表明当基脉比为0.4，脉冲频率为500 Hz时，超薄N6板焊缝成形质量最好。通过该研究成功实
现了0.1 mm厚超薄N6的脉冲微束等离子弧焊接。 |
| 英文摘要: |
| When the thickness of nickel and nickel base alloy plate is less than I mm. the defects of burning, porosity
and crack in the welding process can seriously affect welding quality. Aiming at the particularity of nickel and nickel-
based alloys and the problems in the welding process, the impulse micro-plasma arc welding was used to weld 0. I mm
thickness nickel sheet. Under the same duty ratio and different pulse frequency as well as base pulse ratio condition. the
forming quality of nickel plate was analyzed and the suitable process parameters were obtained. The result shows that the
forming quality of nickel plate is the best when the base pulse ratio is 0.4 and pulse frequency is 500 Hz. Through this
research, this paper successfully realizes the pulsed micro plasma arc welding of ultra thin N6 with 0. I mm thickness. |
