英文摘要	The behavior of the welding pool plays an important role in determining the quality of the weld, and the surface behavior of the welding pool contains some important information as feedback to adjust welding parameters. In order to study the dynamic characteristics of the molten pool surface in the TIG welding process with the filler wire, a grid structure laser measurement platform, based on the principle of surface reflection, was designed to observe the molten pool surface in this work. CCD was used to record the imaging on the projection screen. A new three-dimensional reconstruction algorithm was proposed for calculation of the welding pool surface. This algorithm analyzes the image which is captured by the CCD to restore the three-dimensional topography of the fixed-point wire-filled TIG welding pool, so as to obtain the three-dimensional topography evolution the during welding process. The difference between the obtained weld pool height and the experimental results is very small.
