爆炸焊接界面波形参数的影响因素

Influencing factors of wave parameters for the explosive welded bonding interface

采用不同的爆炸焊接工艺爆炸复合了铝合金/纯铝/钢与铝合金/钢/钢复合板,并对其结合界面形态进行了显微观察与分析,测量了爆炸焊接界面的波形参数,探讨了不同爆炸焊接工艺及不同材料对爆炸复合界面波形参数的影响.结果表明:爆炸焊接界面波形受爆炸焊接工艺及材料性能的影响,当基、复板材料性能相差较大时,易形成平直界面,波形不明显;当基、复板材料相同或相近时,界面易形成有规律的正弦波形.当焊接材料相同时,随着爆炸焊接装药密度的增加,界面波长、波高均有所增加.

Aluminum alloy/aluminum/steel and aluminum alloy/steel/steel cladding plates were exploded by different explosive welding technologies. The bonded interface＇s configuration was observed and analyzed, and the wave parameters were measured by optical microscope. The results show that the wave configuration of the bonded interface depends on the explosive welding technology and material properties. A line-straight bonded interface formed when the properties of the base plate and flyer plate were greatly different. However, a regular sine wave shape was easily generated when the base plate and flyer plate were the same or their properties were similar. The wave length and the wave amplitude become bigger with increasing explosive density.
