英文摘要	The collapse of three dimensional welding stacking in the end portion of the weld pass was studied by micro plasma arc welding on the 3D motion platform. 3D welding stacking pocess was tracked in real time by using a CCD camera. The change of the weld pool and the droplet transferring were observed and analyzed. The influence of welding force and welding parameters on the collapse was investigated. Experimental results showed that the reasons of the collapse in the end portion of the weld pass include the flow of molten metal and the lack of the filler metal due to the fact the liquid metal pressed to the rear end of the weld pool, which can not be returned and the last molten droplet on the wire is not transfer to the weld pool. Especially, the accumulation of sinking in the end of stacking wall resulted in the droplet not transfer stably to the molten pool, and it makes the collapse further exacerbate. As the result, 3D welding stacking process is hardly continued. © 2018, Editorial Board of Transactions of the China Welding Institution, Magazine Agency Welding. All right reserved.
