Weld access hole
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.
