Study on Pressure Control System of Friction Stir Welding
In this paper,the friction stir welding of 6 series extruded plate and 5 series rolled plate is carried out.By adjusting the welding process parameters,the specific influence of each parameter on the axial pressure and the change law of the axial pressure are obtained.The results show that both the control methods of constant displacement and constant pressure can obtain the weld with good appearance and internal quality.When the welding speed is constant,the axial pressure decreases with the increase of the stirring head speed.When the stirring head speed is constant,the axial pressure increases with the increase of the welding speed.
