Sheath - what is it? For an ordinary person, this word will certainly arouse interest. It's completely unclear what it means. However, this thing is very necessary in any production. It is easy to make it if you have the necessary skills. So, answering the question, the shell - what is it, it should be said - is a blank that is used to create cylindrical and conical structures. It is made from sheet metal by welding. Opposite ends join to form a tube, reservoir, or rim.
Where to start
Manufacture of shells begins with the choice of a suitable material. Long-term practice shows that the best of them is steel 09X18H10T. It is better than others for welding. In addition, this steel allows you to choose from numerous types of welding. The last one is very important. Choosing the perfect welding method is very difficult, but necessary. The best in this case is electro-beammethod.
Advantages of ELM
The shell - what is it, we have already found out. Now let's see why this welding method is used in its manufacture. First of all, it is the quality of the seam. It turns out reliable, and this is of paramount importance. Any defect resulting from welding is easily eliminated. The process can be mechanized. Electron beam welding gives high productivity. If we compare it with other methods, then the indicators of the latter will be 20 times lower. In this regard, ELM is the method by which the shell is made. Photos can show - the output is a high quality item.
ELM quality
It was also noted that during EL welding, heat quickly leaves the working area. Along with a small amount of heat, which is necessary for this welding method, a slight deformation of the manufactured objects is obtained. Having learned the answer to the question, the shell - what is it, you probably understood - this is an object of different sizes, which is easy to make if you know the technology and have certain skills.
