Comparison of Numerical Simulation with Experimental Measurement of Temperature Field and Welding Deformation in Different Welding Sequences of Welding T-Joint

The estimation of temperature field and welding deformation plays an important role in welding technology. The accuracy of the numerical simulation will reduce the cost of experimental measurement. This paper suggests the numerical simulation of the temperature field and welding deformation of the welding fillet joint, or welding T-joint, in different welding sequences. The first contribution of this paper is proposing the numerical model to simulate the heat transfer between the metal plates and the thermocouple sensor. The second contribution is that the paper shows the mechanical deformation in many welding sequences and concludes which welding sequence can give the smallest deformation. The proposed numerical model is verified by the experimental results.
