Hello guys. Today we will easily become to expand the horizons of the welding process. Namely, let's find out what the temperature is in the arc of manual arc welding.
The arc is formed as follows. At the moment of contact the electrode metal surface is obtained a short circuit between the microprotrusions on the surface of the electrode and the welded metal of high .Tok all density instantly melts the protrusions, and of a second welding arc arises which melts the metal electrode and the metal surface, forming a weld bath.
Let's not long to go to the classification of the processes in welding arc, we just know that the temperature of the welding arc is 7000 - 8000 ° C. A lot, right?
Therefore, the arc as quickly melts all kinds of metal, because their melting point is much smaller. For example the melting temperature of the steel is approximately 1500 degrees that is five times smaller than the arc temperature.
Therefore, doing welding, you need to understand how much heat is released and the process to be extremely cautious, protected by special clothing.
