| Abstract Scope |
Temperature control in friction stir welding (FSW) is crucial for achieving desired weld properties, particularly in aluminum applications. Maintaining a consistent temperature, even with changing boundary conditions, allows better control of the material's thermal history. This control facilitates the development of welding parameters and ensures uniform properties along the weld length. Proportional-Integral-Derivative (PID) control methods can maintain constant temperatures during FSW. These controllers must be specifically tuned to the alloy, material thickness, tool geometry, and the machine. The heat generation varies with different aluminum alloys, requiring tailored PID gains for optimal performance. While PID gains for FSW can have a range of values that perform similarly for the same alloy, tuning controller gains is essential to achieve optimal control performance. We have demonstrated that gains vary with different thicknesses of the same alloy and that the time delay used in the digital controller impacts optimal gain values. |
