identify the features of the profession "Welder (electric welding and gas welding work)”, the dominant activities of this profession, important qualities, knowledge and skills that a future specialist should possess;
find out what role physics plays in the development of my profession.
The task of the work is to develop a booklet on the profession "Welder (electric welding and gas welding)" as agitation and career guidance.

welding of parts, products,

Types of activity of the welder:

welding of parts, products,

different kind

technical compliance
In the process of welding, an experienced craftsman, like a sculptor, creates complex objects from metal: from a water supply system to restoring the geometry of a car body.

Profession requirements for a person:

Physical strength and endurance, since the work of the welder is mostly manual. Visual acuity and color perception. Flexibility and mobility of the hands. Developed vestibular apparatus, good coordination of movements. The ability to focus for a long time. Spatial imagination and technical thinking. Accuracy, emotional stability, balance

Profession risks

The advantages of the profession include prestige and high demand in the labor market. Young specialists who have just graduated from college will not have to look for a job for a long time. Welders without experience are willingly accepted into housing and communal services, into private service organizations. With the acquisition of experience, they are entrusted with more responsible affairs and work in industry, at construction sites. Accordingly, the salary increases.

The disadvantages of the profession are difficult working conditions, work on open construction sites in any weather, a large load on vision due to the high brightness of the electric arc, infrared and ultraviolet radiation. Electric welders belong to the professions of the "hot shop" due to the high hazard of production due to the large release of gases and heat during welding.

Physics in the profession of a welder: Conclusion:

Knowledge of physical laws in the field of electricity, thermal phenomena, molecular physics is the foundation for studying the functioning of devices and instruments, technological skills in mastering the profession "Welder (electric welding and gas welding)".
The task of the work is to create a booklet on the profession as an agitation

Physical phenomena are an integral part of the world around us, which is based on the laws of this science. Therefore, it is not at all surprising that any profession, whatever it may be, is somehow connected with physics.

I want to become a doctor in the future. For this profession, such subjects as chemistry and biology are of paramount importance, therefore, it is their applicants who pass when entering a medical university. But physics for the doctor is also far from last.

This science underlies the work of many body systems. So, our heart in combination with blood vessels is nothing more than a biological pump, on the work of which, for example, human pressure depends. We perceive visual information with the help of the organs of vision, and the lens located inside each eye acts as a biconvex lens that refracts light.

Based on the laws of such a branch of physics as optics, not only our eyes work, but also many medical equipment. First of all, these are microscopes necessary for studying the structure of human body tissues and microorganisms.

X-ray machines and magnetic resonance tomographs, which are used in clinics to study the state of human internal organs, are also equipment whose operation is determined by knowledge of the principles of various physical processes. Ultrasound also became possible only after the discovery sound waves with high vibration frequency (ultrasound).

Of particular importance is physics for dentistry. In the future, I want to become an orthopedist and install dental prosthetic structures, so it is very important for me to understand the various properties of solids and study the laws of mechanics. Without this knowledge, I will not be able to work in my chosen profession, and therefore, already now, while studying at school, I am doing my best to master a difficult, but so necessary science for a doctor.

Physics is the science of nature in the most general sense. It studies mechanical, electrical, magnetic, thermal, sound and light phenomena. Physics is called "fundamental science". Therefore, its laws are used in almost all areas: medicine, construction, in all areas related to technology, in electronics and electrical engineering, optics, astronomy, geodesy, etc.

Physics in construction

Building physics studies in detail the phenomena and processes associated with the construction and operation of buildings and structures. These phenomena and properties are characterized by physical quantities. Construction activities are inextricably linked with certain environmental conditions: temperature, humidity, air composition, substance density.

First you need to study the area where the construction will take place. This is what geodesists do. Engineering geodesy studies the methods and means of geodetic work in the design, construction and operation of various engineering structures. The tasks of geodesy are solved on the basis of the results of special measurements performed using geodetic instruments, since it is necessary to evaluate the site of the proposed construction. you need to get information about the terrain. All these calculations serve as the basis for the design of structures and buildings. And here you can not do without the laws of physics!

Physics in the profession of Architect

The profession of an architect involves architectural design at a professional level. The duties of a specialist include the organization of the architectural environment, the design of buildings and the development of space-planning and architectural solutions.

In architecture, the laws of physics are of great importance, which help to consider the role of the concepts STABILITY, STRENGTH, RIGIDITY OF STRUCTURES, as well as the role of floors and foundations in the construction of buildings, deformation of structural elements and calculation. Using the laws of statics for

Physics in the medical profession

At present, the line of contact between physics and medicine is extensive, and their contacts are constantly expanding and strengthening. There is not a single branch of medicine where physical instruments are not used to establish diseases and their cures.

The most important part of the human body is the circulatory system. The action of the human circulatory system can be compared to the work of a hydraulic machine. The heart works like a pump that pushes blood through the blood vessels. During heart contraction, blood is forced out of the heart into the arteries, passing through valves that prevent it from returning to the heart. Then it relaxes and during this time it fills with blood from the veins and lungs. Opening simple ways Blood pressure measurements have made it easier for doctors to recognize diseases that are characterized by abnormal blood pressure.

Physics in the profession of a cook

Molecular physics and thermodynamics are very important branches of physics for a cook. As the saying goes- good result It cannot be accidental... So, to prepare a good steak, you need to put it on a hot frying pan and add a small amount of fat or oil.

The oil will clog the holes in the meat and it will cook juicy.

Physics in the profession of a photographer

The profession of a photographer is closely connected with the science of "Physics".

Concepts such as focus, lens, etc. belong to this profession.

The main element of the apparatus is the lens. Without it, there would be no microscope, no telescope, no glasses... And this means that many people over 50 could not read, biologists could not study cells, and astronomers could not study space.

Physics as a nuclear engineer

Here, physics is used to solve the problems of nuclear energy enrichment.

Nuclear physicists, together with atomic physicists, study the structure of the atom and the processes in it, and not infrequently make great discoveries.

Physics as a petroleum engineer

The use of internal combustion engines, the development of mechanical engineering, and the aviation industry became possible with the discovery of more and more new oil fields. Huge oil reserves allow the development of the industry.

In this profession, researchers are discovering new ways to improve oil and natural gas production.

Physics in machine, aircraft and rocket science

A designer of rockets, space stations, satellites, anti-missile systems must know physics and understand the essence of physical processes...

Specialist in informatics and computer technology

In modern life, a lot of information technology tools have appeared, with the help of which you can create presentations for lessons, recreate experiments and scientific discoveries of ancient scientists, and all this with the help of animation, raster and vector graphics, video. All these methods greatly facilitate the life of modern teachers and teachers.

The impulse turns into numbers, numbers into binary code... that's why physics is present in computer science.

The objectives of our lesson: Educational: to show the role of physics in modern working professions; Educational: to cultivate purposefulness, independence, attentiveness Developing: to develop cognitive and Creative skills for self-study Equipment: computer: presentation: "Physics in your profession" (Wednesday power point, Paint, Word), video clips, animations 2
