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 metal structure basis (Part 2).
As we mentioned earlier, at any given temperature, the metal atoms are at the strictly defined distance from each other. In other words, they carry in themselve...
The polymorphic transformations in alloys (Part 2).
The polymorphic transformation of the solid solution upon heating and cooling consists of the lattice rearrangement and diffusion redistribution of the componen...
The non-existence of defects monitoring in the weld seams (Part 2).
The second type of the bending test equipment with a mandrel is a standard device in which hardened bearings on the matrix are replaced by rollers. This helps t...
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...
