Modelo energético doble elipsoidal oscilatorio para soldadura por arco

In the present work, anoscillatory and double ellipsoidal energetic model of thermal heat source for the cold metal transfer (CMT) welding process simulation was proposed.The sinusoidal solidification sequences model of the surface ripples and the oscillation frequency of the electrical welding parameters was proposed. The model was developed from the mathematical analysis of serial functions of energy and dimensional contribution to the electric arc and the description of electric cyclic phenomena and weld joint formation.As result, the frequency of electrical occurrence and energetic phenomena of the arc must not coincide with the formation of the fused weld pool was obtained, considering the process as periodic sinusoidal functions. It was explained how to determine the value of the medium heat supplied for a sinusoidal approximation of the introduced power behavior.
