Characteristics of weld-bonded commercial aluminum sheets (B.S. 1050)

The aim of the present work is directed towards the manufacturing and characteristics of weld-bonded commercial aluminum sheets. Dynamic response (natural frequency and damping), nugget size, and tensile shear strength were tested and reported. The present work demonstrates a tremendous improvement in tensile shear strength associated with higher damping capacity for weld-bonded joints. However, the natural frequency seems to be independent on shear strength as well as joining technique (spot welding or weld bonding).
