Training of file saw workers

Teaching plan of welding technology specialty

First, the training object and educational system

Training goal: dual-use talents.

Educational system: 1 year

Second, the occupation post analysis

Welding is an important part of manufacturing industry, which is widely used and develops rapidly, and occupies an important position in manufacturing industry. China is a big country in steel production, steel use and welding in the world. With the continuous emergence of high-tech and new technology, machinery manufacturing, installation and maintenance industries are gradually developing in the direction of refinement, and the requirements for welding technology are getting higher and higher. In recent years, the use of CO2 gas shielded welding has increased rapidly. The technical transformation of welding mechanization and automation has been accelerated; In automobiles, auto parts, rolling stock and other manufacturing industries, the number of welding robots is increasing rapidly. The welding automation rate is rapidly improved. At present, the welding talents in China are mainly junior welders, and the proportion of middle and senior workers is extremely low, which seriously restricts the development of China's welding manufacturing industry. High-and middle-level workers are urgently needed talents for China's economic development.

Third, the employment situation

Graduates are mainly engaged in welding technology in steel structure construction enterprises, petrochemical equipment installation enterprises, machinery manufacturing enterprises and automobile manufacturing enterprises. Engaged in welding, cutting, welding process service, welding inspection, welding equipment debugging, processing, assembly and welding related work of ordinary metal materials and special steel in machinery manufacturing and machinery maintenance enterprises.

Fourth, the training objectives

Six, curriculum and requirements

1, mechanical drawing

Make students master the basic knowledge of mechanical drawing, basic projection theory and relevant national standards. We should give priority to map recognition and combine map recognition with drawing. Emphasis is placed on cultivating students' drawing reading ability, which requires students to understand the assembly drawings of parts with moderate complexity, master the basic knowledge and skills of drawing, and have the ability to draw complex parts drawings and simple assembly drawings.

2, tolerance and technical measurement

To enable students to master the dimensional tolerance, form and position tolerance, surface roughness, the solution and marking of various codes, the calculation and application of various matching systems, and the correct use, management and maintenance of commonly used measuring instruments.

3, metal materials and heat treatment

Enable students to master the brand, composition, performance and application scope of commonly used metal materials, initially understand the internal structure of metal materials, and understand the general relationship between composition, structure and performance of metal materials. Master the general principles, common methods and applications of heat treatment of metal materials.

4, electrotechnics

Enable students to acquire the necessary knowledge of electrical principles, electrical drive control circuits, electrical instruments, etc. Understand the basic structure, patterns, symbols and main uses of electrical equipment commonly used in general machinery industry, acquire the basic knowledge of correct use, maintenance and safe use of electricity, understand the control circuit diagram of general simple appliances, and understand the basic knowledge of industrial electronics.

5, welder technology

Enable students to fully grasp the technical theory and process knowledge needed for this type of work, and have independent process analysis ability and necessary operation ability for typical workpiece processing methods. Make clear the performance, structure, working principle, relationship and adjustment and maintenance methods of the main equipment and tools of this type of work. Understand the structural principle and correct use and maintenance methods of the main equipment of this type of work. Will consult relevant technical manuals to reach the operating level of intermediate skilled workers.

Welding practice: covered electrode arc welding, CO2 gas shielded welding, manual TIG welding, other welding and cutting methods, metal material welding, typical welding structure welding, welding production and application, etc.

6, riveting process
