Welding Technology…
Resistance welding, mechanical joining and adhesive bonding are highly productive and cost-effective joining technologies widely applied in manufacturing industry especially in automotive, aerospace, electronics and electrical industries. Resistance spot welding is predominantly used for joining thin sheets such as assembly of car body-in-white. Resistance projection welding is more used for joining complex or small parts such as nut welding, electronic circuits and electrical connectors. Mechanical joining processes including self-piercing riveting (SPR) and clinching are mostly used for assembly of cars with aluminum sheets, and also for joining dissimilar materials such as aluminum and steel or metal and carbon fiber materials. Adhesive bonding is increasingly used in car body assembly often combining with spot welding or SPR to improve the overall strength and stiffness of the car and crash performance.
These welding and joining technologies are constantly advanced through technological innovations aided with welding simulations and optimizations.
