With the development of humanity and develop promising new technologies in industrial production, invented a fundamentally new types of equipment. These scientific knowledge to help people improve and to strive for new achievements. Currently, the industry can get a strong connection elements with different methods of welding. Welding itself was invented not so long ago, but within a short period of time it managed to establish itself firmly in the modern life and has found wide application in all industries. But what is welding? Welding – a power-consuming process of obtaining one-piece construction expense of establishment of the atomic-molecular bonds between the two elements that you want to connect through the full or local heating, or plastic deformation.

Welding is divided into classes: 1. Thermal. To know more about this subject visit electric cigarettes . Thermal class is also subdivided into: a. Arc Electric Welding: manual arc welding, welding consumable electrode welding with consumable electrode arc welding with flux b. Flame welding and in.

Electroslag welding, plasma welding, the, etc. Electro-Radiation, Radiation is welding. 2. Thermomechanical. Also subdivided into: a. Contact: butt, embossed, spot-b. Diffusion; in. Blacksmith, welding, the use of high-current, on friction welding. 3. Mechanical Class: explosion welding. For each welding may require special welding electrodes CL. Then there are such methods, when an employee must perform their work in different spatial positions, in such cases it is necessary to choose the right welding electrodes. Properties of welding electrodes are directly dependent on the coating. There are four types of coverage: 1.Kislye; 2.Osnovnye; 3.Tsellyuloznye; 4.Rutilovye. Now let's talk about each coverage separately.
