Today we will talk about how spot welding for 18650 batteries takes place. This method of connection of cans can be found in almost all professional devices. This is largely due to the processes of production of battery packs, the company brazes them robot. Of course, you can entrust this business to two dozen workers with soldering irons in their hands, but it will be more time-consuming and more energy-consuming.
Spot welding for batteries is a relatively new and sought-after type for battery Assembly. In fact, this type of soldering, let's call it so, came to us from the automotive industry. For many years, the car body, or rather their components, were fastened together by point (contact welding). What are its main advantages? Perhaps the priority should be attributed to the speed and reliability of the connection. Imagine if every seam in a car was first treated with solder, then heated and brazed, about the same thing would be with the use of conventional welding. In addition, a reliable weld in modern conditions can provide only laser welding, but also point at the time coped with this perfectly.
When replacing the batteries in the screwdriver, it is necessary to clearly understand what exactly is meant. Let us explain, the word battery in this case can denote as the battery pack inserted into the screwdriver, and its elements, more precisely banks.
