It is one of the world's most famous car manufacturers. At Tesla's production facility in Fremont, California - the rolled-up aluminum turns into fully assembled cars in just 48 hours. Vehicles begin to be built in the stamping area where metal sheets can be opened and cut to turn doors, hoods, trunks and other parts. The machine that presses itself in various ways works with extreme accuracy. See how the arm of a robot barely survives a crushing blow. The parts are then placed on a conveyor belt provided by CleanTechnica. Staff inspects everything - in this case, side panels - before sending them to be stored inside a large container. The next stop is the body shop - where the robots come together to form the car's bones. 5,000 welds are required for the Model 3, Tesla’s first inexpensive car. The body line is much more automated than the ones used to make the Model S or Model X. Unlike these two cars, the Model 3 is designed to be made on a larger scale as it attracts more customers. Tesla's production methods could change on the plane. A few years ago, while the company was striving to build cars faster, it decided that about 300 welds were not needed and redesigned the robots to eliminate them to save time. Time is precious if you plan to produce 20 million cars a year by 2030. After the finishing touches, the cars move on to paint. The following comes the main attraction: general assembly. 

All the major parts of the car including the battery are assembled together - known as "marriage". Marriage is the most difficult part. As the saying goes: If you go to hell, keep going. Elon Musk described the whole assembly process as a "hell of production" a few years ago when Tesla struggled to build its own cars fast enough. It even set up an additional assembly line under a large white tent in the factory parking lot to bring out other Models 3. "Large" does not accurately define the size of the tent. It was bigger than two football fields. Tesla blamed the delay on issues at Gigafactory in Nevada where it made its batteries. But in an interview with GSle King for CBS, Musk explained that there are also problems here in Fremont. Elon, part of the thing I heard about the Model 3 is that there are so many robots. That's probably ... yah, yah, I agree. You think so, do you? Yes. That you probably need a lot of people working here. We do. In some cases, robots have actually reduced productivity. Yes, they did. We had this crazy, complex network of conveyor belts and it didn't work, so we removed all of this. Musk spent a lot of time in the factory, including sleeping there all night trying to solve problems.

Tesla has managed to get through that difficult time by striking a better balance between the number of robots it uses and the number of human assisted hands. A good example of that balance is a few blocks from a large factory where Tesla makes chairs. Fine fingers are important in the production of car seats. Pull the artificial material over the seat foam, align it, stretch it, and remove wrinkles. Most automakers use the power to make seats and Tesla used to do the same. But when a contractor had trouble building Model X seats, Tesla decided to move all the work inside the house. The equipment has a big role to play as well, especially when the seats are ready for the final assembly. Even here Tesla is focused on saving time. This tube feeds the robots so they do not have to physically pick them up. The air gun shot them through an empty tube as shown by CleT Technica and shaved for about a moment or more. Every second counts. When the seats are ready, they get into the car. And after the Telas found their tires and wheels, they left the assembly line. Designing one of the most advanced and efficient industries in the world is insane. And now ,Tesla is repeating it in its factories in Berlin and Shanghai. It inevitably helps to get rid of petrol cars.
