Weld access hole

Weld Access Hole Sketch

The weld access hole or rat hole is a structural engineering technique that allows welding flanges of I-beams and T-beams across their full width and also minimize the induction of thermal stresses with a combination of partially releasing the welded section, avoiding welding the T section where the flange joins the web and improving cooling conditions.[1][2]

The configuration adopted for web access holes also affects the performance of moment connections due to factors such as stress concentrations.[3]
