Welding works.

There are different types of technologies used for welding. In each case, select the most effective and appropriate way.

Manual arc welding. In manual arc welding with coated metal electrodes, arc lights from the electrode to the product, melted edge welded product and melting metal electrode rod and coated electrodes. Crystallization of the base metal and the electrode rod forms a weld.

Resistance welding - is the formation of compound by heating a metal passing through it an electric current and a plastic deformation zone compounds compressive force.


Methods for welding:

  1. Spot welding
  2. projection welding
  3. seam welding
  4. Butt welding
  5. Capacitor welding

Plasma welding. The plasma arc is characterized by a very high temperature (up to 30,000 0 C) and a wide range of regulation of its technological properties.

Gas welding. Flame treatment of metals - a number of processes associated with the processing of metals high-temperature gas flame.

Electron beam welding. The essence of the process is to use the kinetic energy of the flow of electrons moving at high speeds in vacuo. When welding with an electron beam penetration is conical. Melting the metal is on the front wall of the crater, and the molten metal is moved along the side walls to the back wall, where it crystallizes.

Friction welding. Friction welding - a kind of pressure welding, in which the heating is carried out by friction caused by the movement (rotation) of one of the connected parts to be welded.

Laser welding. The irradiation of the surface of the body with light energy quanta (portions) of the light is absorbed by the surface. Generated heat, the surface temperature increases. If the light energy to concentrate on a small portion of the surface, it is possible to obtain a high temperature. This is the basis welding light beam optical maser - laser.
