采用爆炸焊接工艺生产双金属耐腐蚀钢管。不锈钢管（内管）和碳钢管（外管）的可焊性窗口通过使用可用的半经验关系来确定。通过有限元模拟计算了作为最重要碰撞参数的管道冲击速度。研究了爆炸质量减少对管道粘合界面的直接影响。光学显微镜研究表明，随着爆炸载荷的减少，会发生从波状界面到平滑界面的转变。
Bi-metallic corrosion resistant steel pipes were produced through explosive welding process. The weldability window of the stainless steel pipe (inner pipe) and the carbon steel pipe (outer pipe) was determined by the use of available semi-empirical relations. The impact velocity of the pipes as the most important collision parameter was calculated by the finite element simulation. Direct effect of the explosive mass reduction on the bonding interface of the pipes was studied. Optical microscopy study showed that a transition from a wavy interface to a smooth one occurs with decrease in explosive load.
