The amount of metal evaporating from the cathode spot (Part 1).
When welding with the direct polarity, the dimensions of the anode spot determine the width of the weld. At the same time, at the given current and voltage, on ...

The crystals shape (Part 1).
The shape formed in the melt of the crystals depends on the growth conditions (overheating and supercooling liquid heat removal direction, and other impurities)...
The polymorphic transformations in alloys (Part 4).
The polymorphic transformations in alloys lying outside the eutectoid (KML) and peritectoid (MKL) lines do not differ from the one considered earlier (see Fig. ...
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 ...
