The power supply classification features. The potential distribution in the arc. The welding arc properties (Part 1).
The arc power supply is classified according to the following characteristics: by the current type: a) alternate current: transformers, elevated-frequencies gen...
The metal structure basis (Part 3).
During the welding heat is not transmitted in the uniform manner. The certain part of the metal part is heated to a very high temperature, while the metal tempe...
The polymorphic transformations in alloys (Part 3).
The diffusionless transformation can occur as a result of the disordered atomic transitions (it is called «massive»). It is possible to combine the ordered, coo...
The non-existence of defects monitoring in the weld seams (Part 3).
The next type of defects monitoring, which we will consider, is based on the sample destruction of the welded joint with notches along the weld. This type of te...
