Shell-what is it? Manufacturing process

Shell-what is it? In ordinary people this word will certainly be of interest. After all, it is completely unclear what it means. Nevertheless, this thing is very necessary in any production. Make it with the necessary skills is easy. So, answering the question, the shell, what it is, it should be said, is a blank that is used to create cylindrical and conical structures. Make it from sheet metal by welding. Opposite edges join and form a pipe, reservoir or rim.

Where to begin

Manufacture of shells begins with the selection of suitable material. Many years of practice shows that the best of these is the steel 09X18H10T. It is better than others for welding. In addition, this steel makes it possible to choose from numerous types of welding. The latter is very important. Finding the ideal welding method is very difficult, but necessary. The best in this case is the electro-beam method.

Benefits of ELMs

Shell - what is it, we already found out. Now we will understand why this method of welding is used in its manufacture. First of all, this is the quality of the seam. It turns out to be reliable, and this is of paramount importance. Any defect resulting from welding is easily eliminated. The process can be mechanized. Electron-beam welding provides high performance. If you compare it with other methods, then the indicators of the latter will be 20 times lower. In this connection ELM is the method by which the shell is made. Photos can show - the output is a detail of high quality.

Quality at ELM

It was also noted that when EL welding, heat quickly leaves the working area. Along with a small amount of heat, which is necessary for this welding method, there is an insignificant deformation of the produced objects. Having learned the answer to the question, the shell - what is it, you probably understood - is an object of different size, which is easy to manufacture if you know the technology and have certain skills.
