1. The examination content of the welding direction postgraduate examination mainly covers the following aspects:
Basic knowledge of welding: This part mainly includes the basic principles of welding, the physical and chemical processes of the welding process, the formation and characteristics of welded joints, etc.
Welding Methods and Techniques: Candidates need to master common welding methods and techniques, such as manual arc welding, gas shielded welding, laser welding, brazing, etc., as well as understand the advantages, disadvantages and application scope of these methods.
Welding materials: The selection and use of welding materials is crucial to the welding results. Candidates need to understand the properties, classification, and usage methods of commonly used welding materials, as well as precautions in the welding process.
Welding Defects and Quality Control: Candidates need to understand the defects that may occur in the welding process, such as porosity, slag inclusion, lack of fusion, etc., and how to reduce or avoid these defects through quality control means.
Welding Process Qualification: Candidates need to understand the basic concepts and methods of welding process qualification, and how to formulate a reasonable welding process according to the mechanical properties and corrosion resistance requirements of welded joints.
Second, is it easy to take the postgraduate examination in the welding direction?
In terms of difficulty, the difficulty of the postgraduate examination in the welding direction varies from person to person. For students who already have certain welding knowledge and skills, it is not very difficult. However, for students who have not been exposed to the welding field, it takes more time and energy to learn and master the relevant knowledge and skills Xi.
In general, the difficulty of the postgraduate examination in the welding direction is not very large, but candidates need to have a relatively solid basic knowledge and skills. If candidates can prepare carefully, understand and grasp the content of the exam, they may achieve good results.
As for the difficulty of the graduate school entrance examination, it actually depends largely on the individual's ability and effort. If candidates have a solid academic foundation, good study habits and correct learning methods XiXi the Xi, and at the same time can devote themselves to and actively prepare for the exam during the preparation period, then the difficulty of the postgraduate entrance examination will be relatively low.
