Title: Exploring the beauty of craftsmanship in making large outdoor stainless steel spheres
In the corners of the city, you can often see some eye-catching outdoor sculptures in parks, squares, art galleries, etc., many of which are large stainless steel spheres. These spheres are graceful in shape, smooth and bright, giving people a visual impact. So, how are these made? Today, let’s explore the manufacturing process of large outdoor stainless steel spheres.
cutting material
First of all, making stainless steel spheres requires a large amount of stainless steel materials. Generally speaking, stainless steel plates are the most commonly used raw materials. During the production process, these stainless steel plates must first be cut. The accuracy of the cutting process directly affects the smooth progress of subsequent processes. In order to ensure the accuracy and efficiency of cutting, modern manufacturing often uses CNC cutting machines to perform automated cutting through pre-designed programs to ensure that the size and shape of each plate can meet the design requirements.
Welding process
The cut stainless steel plates need to be welded next. Welding is a key link in joining parts together accurately. When making stainless steel spheres, argon arc welding technology is often used. This welding method can ensure the quality and beauty of the weld. During the welding process, the welder needs to weld each part one by one according to the design drawings to ensure that the welding points are firm and the overall structure of the sphere is stable.
hydraulic process
After welding is completed, the next step is to shape the stainless steel sphere. Hydroforming technology is often used here. The so-called hydroforming uses high-pressure water flow to gradually press the stainless steel plate into the shape of a sphere. During the hydroforming process, the size and direction of the water pressure need to be controlled to ensure that the stainless steel plate can be stressed evenly to form a smooth and symmetrical sphere.
Polishing process
Finally, the stainless steel sphere after hydroforming needs to be polished. Polishing is to make the surface of the sphere smoother and brighter, and increase its ornamental value. The polishing process generally uses a combination of mechanical polishing and manual polishing. Through advanced polishing equipment and skilled operating techniques, the surface of the stainless steel sphere can be made to have a mirror-like effect, reflecting charming light.
Through the above process flow, we can see that the process of making large outdoor stainless steel spheres is not simple and requires multiple processes and exquisite skills. Every process carries the wisdom and sweat of the craftsmen, and the beautiful stainless steel spheres finally presented to us are the crystallization of these processes. They are not only a beautiful sight in the urban landscape, but also a manifestation of the beauty of craftsmanship, which makes us marvel at them.
