A Weld Detection System For Measuring Residual Stress Of Welded Products And A Method Thereof

Abstract: The present disclosure provides a weld detection system (102) and a method (300) for residual stress measurement. The weld detection system includes a fixture (106) adapted to support an electric resistance (ER) welded product (104). Further, the weld detection system includes a control circuitry (118) configured to receive real-time visual media of the welded product while rotating about a central axis (X-X’) of the welded product in the fixture. The control circuitry detects a weld region (202) in the welded product by applying image processing techniques to the real-time visual media. Further, the control circuitry assigns a label indicative of a reference position (204) to the weld region. The control circuitry facilitates rotation of the welded product about the central axis for a preferred circumferential location from the reference position to compute residual stress in the welded product.
