How Resistance Welding is Used Today

Picture
          Today Resistance Welding is used in many different applications.  Take for instance the picture of the truck on the left, most of the body panels have been welded by using a resistance welding process know as spot welding.  This process is perfect for the manufacturing of vehicles due to the increased speed and the increased ability to design crumple zones.  Most vehicles (mainly cars) are pretty much sheet metal that is spot welded together to form the entire structure of the car.  This allows for the vehicle to be lighter (save's gas and materials) and also safer for the operator.  The increased safety is due to the crumple zones that the cars are now manufactured with.  The crumple zone is where the vehicle will fold and crush absorbing energy so that the operator of the vehicle will survive but it causes the vehicle to be totaled pretty much every time.  Resistance Welding is also used in manufacturing fuel tanks, medical equipment such as tables, refrigerators, and many other house hold items.
