Thermal stresses developed in weld-bonded joints

The weld-bonding process is essentially the spot-resistance welding of parts that subsequently have their overlapping areas adhesive-bonded. Two distinct techniques are normally used for manufacturing weld-bonded structures namely; weld through and flow-in. The present work is concerned with the thermal stresses developed in weld-bonded joints, throughout their manufacturing stage. The most influential factors that have been studied and evaluated are the weld bonding technique, the type of adhesive material, the electrode pressure and the bond line thickness.
