X-raying Welded Steel Frame joint
(OP)
In other countries, steel frame are welded without x-raying the connections. Is it a requirement in the US that each joint is x-rayed to see perfect welding and is this really necessary? In steel frame building, welding is the most important factor and failure of it would lead to collapse of building in the event of even low intensity seismic activities.

AWS D1.1 only requires volumetric NDT when the connection is subject to certain fatigue categories and the load is tensile.
Many designers and owner require complete joint penetration groove welds loaded in tension to be volumetrically examined for peace of mind and to ensure the contractor is in compliance with the code.
