The manufacture of parts, the processing of metal structures is a very promising way to earn money. 
Moreover, you can deal with structures for various purposes.
It would seem who might need metal processing services. However, practice shows that many are interested in such works. Orders for services come both from individuals and from various institutions. First of all, the service will attract the attention of collectors, engineers, craftsmen, various factories, educational and medical organizations.
If before all the metal work was done manually. The blacksmiths spent a lot of time and effort manufacturing products. Now almost all operations on metal are performed by special machines. And the first thing you will have to take care of is choosing the necessary equipment for cutting, welding and bending products.
Today, the most advanced technologies are increasingly used in the production of metal parts. The manufacturing processes of products are constantly being improved. The most advanced methods of metal processing are considered plasma, waterjet, laser cutting. Bending of metal is done in one way. These include: free bending and calibration. It makes no sense to list all types of metal welding, there are many of them. As in the case of cutting, one cannot do without new technologies. An embodiment of a high-tech production process can be laser welding of metal.
In general, laser technology does not cease to amaze specialists with its capabilities. Laser cutting is the most rational way to process metals. A concentrated beam controlled by a computer is capable of performing the most complex work. Laser cutting stands out among other methods in that it makes it possible to produce products with an accuracy of 0.1 mm. When cutting, uneven edges are formed. This fact eliminates the need for painstaking processing of sketches before cutting. While with mechanical methods, the thickness of the tool must be taken into account. Laser cutting makes it possible to quickly produce parts, with very little waste remaining. Another advantage of the laser process is its versatility. Laser cutting is effective both when cutting thick and thin sheets, it is possible to work with brittle materials.
Laser technology can be used when joining steels up to 10 millimeters thick. Laser welding of metal is especially interesting when processing small products. It allows you to weld parts, up to 1 mm. The technological process can be successfully used in jewelry to connect gold and platinum jewelry. It is clear that the main advantage of laser technology is its easy beam control, which allows you to work even in the most inaccessible places.
The main disadvantage of laser technology is the high cost of equipment. But with competent organization of production, all the costs of opening an enterprise pay off quite quickly.
When organizing the production of processing structures made of metal, it is worth considering the issues of supplying raw materials and compiling a catalog of services. Usually it’s enough to add to the list of products a set of the most popular goods. In special cases, you can use the services of a designer who will prepare sketches for luxury orders. Often the customer has a finished product design. In this case, it just needs to be transferred to the program for working with the machine.
