What is Welding Metallurgy What is its main research content and learning purpose 10

1. Welder is a better type of technical work.

2. Nowadays, young people rarely learn electric welding, and welding is hard work and tiring work in the impression of ordinary people, but in fact, this understanding is one-sided. Modern welders need a lot of theoretical knowledge and rich practical experience, and people with certain knowledge are easy to become good welders.

3. The salary of a good welder is very high. The monthly salary of welding masters is generally about 10,000 yuan.

4. It is easier for welders to find jobs, and a large number of good welders are needed in shipyards, metal structure factories, petrochemical industries, infrastructure projects, etc.

5. The light radiation and smoke in welding have adverse effects on the body, and labor protection should be done according to the regulations.

If you want to apply for a welder training class to systematically learn welders, you will not only be taught welding, usually electric welding, carbon dioxide protection welding, argon arc welding, argon welding, oxygen cutting, plasma cutting and other unified learning, it is recommended that you can go to a professional school to see.

Welding metallurgy, I feel that it refers to some metallurgical knowledge involved in the process of welding metallurgy, to put it bluntly, some knowledge of physical chemistry. The research content is to change the properties and properties of the weld through chemical elements, such as adding the alloying element MN can play the role of deoxidation, and the alloying element chromium should be appropriately added when welding stainless steel, so as to play the purpose of anti-corrosion. The purpose of learning is to better grasp the quality of welding.

The main research direction of welding. Efficient welding method and process intelligent control: focus on the physical basis and energy transmission mechanism of welding heat source, and high-efficiency and high-energy welding methods; Droplet transition, melt pool behavior and weld forming control; quality sensing and intelligent control of welding process; Welding robot and automation system integration technology and equipment.

1. If you are going to graduate school in the direction of welding, the first choice is Harbin Institute of Technology, which is famous in the country, and there are also Harbin Welding Research Institute, Tsinghua University, Tianjin University, and Huazhong University of Science and Technology. Because the postgraduate examination of welding can study welding processes such as welding power supply, metal welding, TIG, MIG welding, etc., or you can also study welding materials or welding equipment and so on!

2. Of course, you can apply for the major of materials science and engineering, which is mainly divided into three secondary disciplines: materials science, materials processing, and materials physics. The best schools for this type of major are the Institute of Metals of the Chinese Academy of Sciences, the University of Science and Technology Beijing, Tsinghua University, Central South University, Northwest University of Technology, Beihang University, Beijing Institute of Science and Technology, etc.

3. In fact, if you are going to graduate school, you can take the relevant major or other majors, which depends on your personal ability!

Personally, I recommend that you have a bachelor's degree in welding, and if you are admitted to graduate school, you should learn welding! Because welding seems to be much better than the study of pure materials, both in employment and in the future development!

The research on the weldability of materials is mainly to study the following aspects:

1) Weldability study of materials.

2) Research on the process characteristics of welding methods.

3) Research on welding materials.

4) Welding stress and deformation research.

5) Preheating and post-weld heat treatment research.

6) Design and experimental research of welding process equipment.

Welding metallurgy mainly refers to the physical nature of welding, the formation of welded joints, and the basic concepts of welding temperature field. welding chemistry state hail metallurgy; welding materials; solidification of the weld pool and solid-state phase transformation of the weld; structure and properties of the heat-affected zone of welding; Weld cracks.

Material weldability refers to the ability of homogeneous or heterogeneous materials to be welded to form a complete joint and meet the requirements of the intended use under the conditions of the manufacturing process.

Weldability has two meanings:

One is binding performance, that is, the susceptibility to the formation of welding defects under the conditions of a given welding process;

The second is the use performance, which refers to the requirements of the welded joints formed by certain materials under the specified welding process conditions to meet the requirements of the use performance.

Weldability influencing factors:

1) Material factors: welding consumables, base metals;

2) Process factors: welding method, welding process;

3) Banquet positive structural factors: structural form, joint form;

4) Use factors: working conditions, load conditions, requirements.

"Welding Metallurgy" is a major professional course textbook for welding majors in colleges and universities, which is compiled according to the syllabus adopted by the Steering Committee for Welding Teaching in Higher Technical Schools. This book is the "Basic Principles" part, the main contents: the physical nature of welding, the formation of welded joints, the basic concepts of welding temperature field; welding chemical metallurgy; welding materials; solidification of the weld pool and solid-state phase transformation of the weld; structure and properties of the heat-affected zone of welding; Weld cracks.

This book reflects the scientific research achievements of welding technology at home and abroad, and is rich in content and luxuriant. This book is not only used as a backbone textbook for welding majors in colleges and universities, but also the main reference book for technicians engaged in welding research and welding engineering.

Here's my personal summary of the principles of welding metallurgy:

In fact, it is to turn the heat energy formed by the conversion of iron into a liquid state, and then turn the metal into a liquid in part to artificially form the various shapes required. In the process of slow cooling of liquid metals, the change of temperature determines the formation of structure, and the properties of each metal structure are different, but it is called metallurgy to artificially control this temperature change to achieve the required microstructure properties.

Welding, also known as welding and grafting, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure.

Steel smelting refers to the extraction of metals from ores by roasting, smelting, electrolysis and the use of chemicals. Reducing the amount of impurities contained in the metal or increasing the presence of a component in the metal.

The two are fundamentally different and have different roles. However, the two are for industry, production, and life services, steel smelting is the foundation, welding is the auxiliary, and it is impossible to directly use smelted steel in many places, so welding is needed.

The welding process directly affects the service life of the steel, especially some parts that are easy to wear, not only the use of wear-resistant steel can be solved, the specific welding process can find some special steel processing plants, the technology is more advanced, such as the law of the steel bmm, etc.

Welding metallurgy, I feel that it refers to some metallurgical knowledge involved in the process of welding metallurgy, to put it bluntly, some knowledge of physical chemistry. The research content is to change the properties and properties of welds by chemical elements, such as adding alloying elements MN can cause lead.

The role of deoxidation, when welding stainless steel, it is necessary to appropriately add the alloying element chromium Huai to play the purpose of anti-corrosion.
