We are using E NicrFe-9 (Weld Metal) electrodes for 9% Nickel plate (Base Metal) welding. Weld metal is having approximately 70% Nickel. The joint is welded from both sides.Is there is any necessary to provide backing strip during radiography to avoid density difference between the Weld metal and Base metal?

It has been a long time since I was involved with this. So, don't take this as expert advice.
I don't think we used a back-up during our X-ray on some 9% nickel cryo tanks. However, one test shot should be all that is necessary to determine if this will be the case.
