This document describes a novel apparatus designed for imparting vibratory weld conditioning (VWC) to mechanically joined weldments. VWC involves vibrating the workpiece during welding to improve mechanical and metallurgical properties by refining grains and relieving residual stresses. The designed apparatus uses a cam-motor arrangement to impart uniform vibration at a variable frequency, as an alternative to existing vibrator-based methods. The apparatus components include a supporting table, helical springs, a rectangular plate to hold the workpiece, an eccentric shaft driven by a motor to transmit vibration, and ball bearings. Experimental results show that VWC using this apparatus can significantly improve weld microstructure and properties compared to normal welding.
