摘要：The pulsed metal inert gas welding and continuous metal inert gas welding with various parameters are implemented on 2-mm-thick Invar36 alloy plates. The pulsed metal inert gas welding and continuous metal inert gas welding with the same filler metal and base metal are compared by considering the morphology, microstructure of weld seam and mechanical properties. It is indicated that the size of weld seam obtained in pulsed welding is significantly different from that in continuous welding. Meanwhile, it reveals that there is a triangle zone at the bottom of weld seam in both types of welding technology for Invar36 alloy. The microstructure in triangle zone of pulsed welding and continuous welding is focused. In addition, the essential difference between pulsed metal inert gas welding and continuous metal inert gas welding is discussed in detail by analyzing the formation mode of the droplet metal at the end of wire. © IMechE 2017.
