TAILIEUCHUNG - Numerical simulation of temperature field during welding of K type pipe joint

This paper studies the finite element method (FEM) to simulate the temperature field during welding of K type pipe joint. Temperature variations at a point (node) in the heat source movement are examined. Using Gas Metal Arc Welding - GMAW, the welding method is now widely used in the fabrication of steel structure. | Journal of Science & Technology 127 (2018) 006-010 Numerical Simulation of Temperature Field During Welding of K Type Pipe Joint Nguyen Hong Thanh1,2*, Nguyen Tien Duong2, Ha Xuan Hung3 1 Nam Dinh University of Technology Education, Loc Ha, Nam Dinh, Viet Nam Hanoi University of Science and Technology, No. 1, Dai Co Viet, Hai Ba Trung, Ha Noi, Viet Nam 3 University of Labour and Social Affairs, No. 43, Tran Duy Hung, Cau Giay, Ha Noi, Viet Nam Received: January 07, 2016; Accepted: May 25, 2018 2 Abstract This paper studies the finite element method (FEM) to simulate the temperature field during welding of K type pipe joint. Temperature variations at a point (node) in the heat source movement are examined. Using Gas Metal Arc Welding - GMAW, the welding method is now widely used in the fabrication of steel structure. The modeling and simulation of the temperature fie ld when welding K joint connection made on the basis of the model Solid (3D). In this paper we use VisualMessh / VisualWeld of ESI Group to model and simulate it. This is a useful simulation tool because it can solve the complex problems of thermomechanical and metallurgical in welding including nonlinear problems, pseudo steady state, kinetics, . Keywords: GMAW, Temperature field, Piping joint, K Joint, Welding numerical simulation. 1. Introduction distortion and phase transformation). The software allows modelling and simulating the welding process most sufficiently and practically. * Simulation allows shortening research time, reducing research cost and reducing the number of experiements. On that basis, the authors choose the software VisualWeld to simulate the structural carbon steel K pipe welding joint in order to study the heat transfer and the formation of residual stress and distortion during GMAW welding. Welding simulation is one of the most useful methods to predict the temparature field, residual stress and distortion using FEM. It is widely known that the temparature process .
