SYSTEM AND METHOD OF MINIMIZING WELD DISTORTION USING PNEUMATIC VIBRATION

摘要

A new technique in welding is provided that utilizes vibration during the welding process. The technique requires a pneumatic control panel having a master pneumatic input and dual pneumatic outputs. Each pneumatic output powers a pneumatic vibrator arranged in a particular orientation with respect to the weldment. The vibrators may be arranged such that the axes of rotation of the vibrators are orthogonal to the vector of the weld seam. The vibrators are set using the pneumatic control panel to vibration frequencies that are out of phase sufficient to form a beat frequency in the weldment. The weld produced when the welding occurs during this vibration yields less distortion and stronger and more predictable welds.
