Evaluation of joining strength of aluminum joining methods

알루미늄 결합법들의 결합 강도 평가

The automotive industry is currently trying to develop light- weight vehicle for both improvement of fuel efficiency and reduction of environmental pollution. For the reduction of vehicle weight, the substitution of aluminum for steel has been increased. However, the change of material causes a significant problem with respect to the method of joining. In this paper, strength of several aluminum joining methods such as spot welding, metal insert gas(MIG) welding, adhesive bonding was evaluated by performing lap test.
