Surface Depression

A three-dimensional model is set up to predict the surface depression of a tungsten inert gas (TIG) weld pool in a full-penetration condition in order to find out the relation between pool depression and weld penetration. It solves pool surface depression, fluid flow and heat transfer simultaneously and determines the configuration of a weld pool surface based on the dynamic balance among arc pressure, pool gravity and surface tension at the deformed weld pool surface. In the numerical simulation, difficulties associated with the irregular shape of the deformed weld pool surface and the liquid/solid interface have been overcome by adopting a boundary-fitted non-orthogonal curvilinear coordinate system. A series of data about pool surface depression under different TIG welding conditions are obtained. The validity of the model is verified through TIG welding experiments.

Abstract In order to study the dynamic characteristics of the weld pool surface during the TIG welding process of the filler wire, an observation test platform for the study of the three-dimensional surface behavior evolution of the TIG weld pool based on the grid structure laser was used to observe the weld pool surface and obtain the reflection grid laser image. The three-dimensional surface evolution of the fixed-point TIG welding pool is accurately restored by the three-dimensional recovery algorithm of the weld pool surface, so as to obtain the three-dimensional surface morphology of the weld pool. The difference between the obtained weld pool height and the experimental results is very small, and the results are basically the same.
