Joining Technologies

Resistance spot welding technologies of high strength steel (HSS) sheets were investigated in order to get high reliability in welded-joints of automobile components. Suitable welding current range shifted to lower currant side by the effect of electric resistance increase of steel sheet and the width of this range was affected by electrode force. Vickers hardness […]

Multi-material design is a clear trend towards achieving optimum lightweight results without compromising on crash safety. Structural adhesive bonding as a joining technique now creates the chance for another route in modern car manufacturing.

Aluminum, or aluminium if you prefer, was first discovered in the early 1800’s and produced in quantity in 1824. By the turn of the century, aluminium was being reliably cast, rolled and formed. Automakers quickly discovered its attributes and it has played an important roll in automobile construction ever since. Aluminum has been used for […]

When designing with aluminum, engineers must not base decisions on prior experiences with steel, or with any other material. Alloy selection, joint design and welding-process selection should all be functions of the base material.
