The metal crystallization.
The changing external conditions, we can get one of the three aggregate states. For the metal that does not experience allotropic transformations, that is, it e...

The static volt ampere characteristic of the arc. The external characteristic of the power source.
The static characteristic of the arc is the dependence of the arc voltage on the current Uд = f(Icв) at the constant length (lд = сonst). The numerous studies ...
The fatigue test.
Another type of mechanical testing, which we will consider in this series of articles, is called the fatigue test. This type of test allows you to determine the...
The self-regulation mechanism of the arc column shape (Part 2).
In the actual welding case, when the product under the arc is melted, the crater is formed, the walls of which direct the reflected gas flow not at an angle of ...
The self-regulatory mechanism of the arc column form (Part 1).
It is well known, that the arc column has the shape of the truncated cone, the larger base of which is on the product regardless of polarity. However, the reaso...
