This paper presents the modeling and simulation of TIG welding in PSpice simulator. The TIG welder unit is modeled by use of a transistor chopper, a PWM generator and an analog PID regulator. The load of the welder unit is the electric arc. The arc model is formed based on the combination and modifications of classical Cassie and Mayr equations. The combination of these two models gives an acceptable...
Development of engineering has resulted product development in model space. Product, analysis, production, and other engineering objects are defined, placed in product structure and related by arbitrary relationships. This model is well-proved and serves Internet based every day work of engineer groups in leading industries. The next step is establishment of a more efficient, knowledge and intelligent...
