Adhesive bonding of oiled steel in the automotive industry

The advantages of adhesive bonding opposed to other joining technologies are as follows: - methods of building using less space, - reduction of weight, - closeness (corrosion protection), - reduction of noise, - possibility of even stress distribution over a large area, - free construction. Experiments with adhesive bonded structural parts have shown that the stability to vibrate and/or the absorption of work could be improved remarkably even after ageing influences compared to resistance spot welding by help of the bonding technic. Without a doubt this fact will help to a further expansion of the bonding technic. Different influences determine wether adhesive bonding is to be used alone or in combination with other joining technologies: production conditions, load of the structural parts, construction. Regarding these there are favourable conditions in the case of the examined joining of the shock absorber. A replacement of resistance projection welding by adhesive bonding is possible . With the combination of adhesive bonding and spot welding a joining method even for oiled steel is available now of that competitiveness will not be limited to the car body construction industry.
