7.6.3. Electric welding installation - a complex of functionally connected elements of the corresponding electric welding and general purpose electrical, as well as mechanical and other equipment, automation and instrumentation, ensuring the implementation of the necessary technological process.

The composition of the elements of electric welding installations depends on their purpose, the design of the equipment, the degree of mechanization and automation.

Depending on the above conditions, the structure of electric welding installations includes cable lines, electrical wiring and conductors of external connections between the elements of the installation, as well as within the installation pipelines of water cooling systems and hydraulic drive, lines of compressed air, nitrogen, argon, helium, carbon dioxide and other gases, as well as vacuum.

7.6.4. Welding current source - a special electrical device capable of supplying electrical energy with the appropriate parameters to convert it into the required amount of heat in the zone of melting or heating of the metal (or non-metallic material) to a plastic state for carrying out the processes specified in 7.6.1.

7.6.5. Welding circuit - part of the electrical circuit of the electric welding installation intended for the passage of welding current from the leads¹⁾ source of welding current to the welded part (product).

1. Conclusion - a term according to GOST 18311-80.

7.6.6. Welding post of an electric welding installation is a welder's workplace equipped with a set of tools (equipment, instruments, etc.) for performing electrotechnological processes of welding, deposition, spraying, cutting.

7.6.7. Single-station or multi-station welding current source - sources of welding current that feed one or more welding stations, respectively.

7.6.8. Autonomous electric welding installations - installations with welding current sources equipped with internal combustion engines, in contrast to electric welding installations powered by electrical networks, including those connected to mobile power plants.

7.6.9. According to the degree of mechanization of technological operations, electric welding installations are divided into installations in which these operations are performed manually, semi-automatic (when the electric welding mode is automatically maintained, and the rest of the operations are performed manually) and automatic.

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Birds also have a cerebral cortex 05.10.2012

The cerebral cortex, the layered structure where the most complex information processing supposedly takes place, was thought to exist only in mammals. In humans, the new cortex - the neocortex - makes up the bulk of the cortex, while in lower mammals it is in its infancy. But a new study from the University of Chicago found that birds, too, have cells very similar to the neocortex, although they are anatomically very different from those of mammals.

A paper on a mysterious structure in the avian brain, published in the Proceedings of the National Academy of Sciences, confirms a long-standing hypothesis that has sparked debate for decades. The study sheds light on the evolution of the brain and opens up new models for studying the neocortex. "We used to be able to study cortical neurons only in mammals," says Dr. Clifton Ragsdale, assistant professor of microbiology at the University of Chicago. "Now we can use other objects for our experiments."

Both the mammalian neocortex and a similar structure in the avian brain called the DVR come from embryonic structures called the telencephalon. But while the neocortex is made up of six different layers of the cortex, the DVR contains large clusters of neurons called nuclei.

Neurophysiologist Harvey Karten suggested back in 1960 that the DVR performs the same function as the cerebral cortex, despite fundamental differences in anatomy. Now Dugas-Ford, Rugsdale and their co-author Joanna Rowell have tested this theory using newly discovered arrays of molecular markers. With their help, it is possible to identify individual layers of the cortex - for example, the "input" neurons of the 4th layer or the "output" of the 5th. The scientists then tested whether these markers are expressed in DVR nuclei. It turned out that even in bird species very distant from each other, all markers of levels 4 and 5 were expressed in certain nuclei, exactly where they should have been in the DVR, if we compare it with the cerebral cortex.

Further experiments should test the developmental stages that form these neurons in different structures, as well as the relative pros and cons of anatomical differences. But it is clear that such a structure in birds, like the cerebral cortex, is capable of supporting extended functions, and perhaps even providing advantages over mammals.
