Fundamentals in Design of Weld Joints

The Technology of Joining metals by welding has undergone considerable developments since its inception The developments an on going process, has been fuelled by demanding application requirements The design methodology of welded joints and fabrication techniques have also evolved with time So is the case with inspection techniques It IS generally agreed that the presence of discontinuities/defects in welded joints is unavoidable The earlier conventional acceptance standards for welds were closely related to
