Weld access hole

The weld access 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 has an impact on the performance of moment connections due to factors such as stress concentrations[3]
