Study on Behaviour of Molten Pool in Arc Welding (2nd Report) : Numerical Analysis of Molten Pool Surface Profile
The molten pool surface profile in arc welding has been analyzed numerically by a finite difference method.In the first part of this report, the numerical method has been discussed and it is made clear that an iterative method of finite difference is useful to solve the non-linear partial differential equation which describes the molten pool surface profile.In the second part, the iterative method has been applied to some typical problems in arc welding and satisfactory results have been obtained.From these numerical analyses, it is concluded that the method, used in this work, is quite available for further investigation of molten pool phenomena in arc welding.
