3.5. The Relationship of Tensile Specimen Fracture Zone and Energy-Input
4. Modeling of the Energy-Input
5. Conclusions
- (1)
- When forging pressure is kept constant, the tensile strength increases with the increase of energy-input until reaching a maximum and then decreases.
- (2)
- Though the maximum temperature has no obvious variation regularity with the change of energy-input, the thermal cycle has a positive correlation with the increase of energy-input, i.e., as energy-input increases, the duration time from the commencement of welding to joint cooling to room temperature increases.
- (3)
- An empirical model was established that describes energy-input as a function of the welding parameters. The accuracy of the model was verified by extra RFW experiments.
- (4)
- An empirical model for the optimal energy-input of different forging pressures was obtained. Then, the optimal energy-input for 170 MPa forging pressure was calculated. Three group experiments were made based on the calculated energy-input value. The joints’ tensile strength coefficients of these three experiments were 93%, 90%, and 96%, respectively. The results proved the accuracy of the model for optimal energy-input.
