Welding Cracks are more significant than other types of welding defects as their geometry produces a very large stress concentration at the crack tip making them prone to cause fracture. Lack of fusion can be categorized into three groups: The following parameters can contribute to the lack of fusion welding defect: To prevent or reduce the possibility of incomplete fusion the following steps can be followed: When the weld metal doesnt completely penetrate the joint, It creates the weld defect known as lack of penetration or incomplete penetration. equations, such as in the use of subscripts, superscripts,
