This squeezing pressure is controlled.
How does welding spot work. Spot welding is a way to attach two metal pieces together at small circular points. Ad Find China Manufacturers Of Welding Wire. Once that lead is pulled away from the material an electric arc is generated.
Its a little like the sparks you see when pulling jumper cables off a car battery. Spot welding works by producing conductive heat. In this video.
It works by contacting copper alloy electrodes to the sheet surfaces whereby pressure and electric. The two workpieces are held together by copper alloy electrodes. Worlds Strongest Man Takes On The Recycling 15 - GEICO Insurance.
Spot welding is a technique generally used to bond metals shaped into sheets no thicker than 3 millimeters. The simplest form of the process is spot welding where the pressure is provided by clamping two or more overlapping sheets between two electrodes Fig. Refer to Figure a.
Spot welding uses the heat from an electrical current to join 2 pieces of metal quickly and is typically used for joining sheet metal. Its often used in vehicle construction but spot welding. The most common type of resistance welding is spot welding.
Resistance welding utilises the Joule heating effect I2R of an electric current passing through a resistor. How a Spot Weld is formed. This welding process is used primarily for welding two or more metal sheets together by applying pressure and heat from an electric current to the weld area.
Other methods rely on pressure to bind metal together and still others use a combination of both heat and pressure. Copper is known for high heat conductivity. Unlike soldering and brazing where the metal pieces being joined remain unaltered the process of welding always changes the work pieces.

In a typical spot welding application there are two electrodes opposite each other which squeeze the metal pieces together.
The process uses conductive heat to connect the metal by using pressure and an electrical current. It is most commonly used for welding sheet metals. Spot welding also known as resistance spot welding is a resistance welding process.
Its also easy to do with a spot welding machine. Another wire known as an electrode lead is placed on the material to be welded. Spot welds are formed when a large amount of current is passed through the panels for the correct amount of time and with the correct amount of pressure.
