Abstract :

Quality assurance has been of a great concern in the process of resistance spot welding, since considerable variation in the weld quality often arises even when the machine variables are held constant. Resistance spot welding is used frequently as a successful joining method for a variety of work commonly in automotive and other manufacturing processes. Spot weld nugget is generally hidden between two sheets, causing its inspection difficult and expensive. Undersized nuggets and excessive–indentation of electrodes reveals the lack of fusion between the parts that can make the weld sub–standard. Visual inspection, pry testing and physical teardown with chisel and hammer method or a combination of them are being used traditionally. This is occur in three stages: Electrodes seated in a weld head are ought to the surface of the parts to be joined and force is applied. Thicker stock is more difficult to spot weld because the heat flows into the surrounding metal more easily. It can be easily identified on many sheet metal goods, such as metal buckets. A large current through the spot will melt the metal and form the weld. The advantages of super capacitor based automated spot welding is widely used in the automotive industries and the process is simple and fully automated so does not required high skills labour and high production rate.
