As an advanced material processing technology, explosion bonded clad plate has been widely used in aerospace, nuclear industry, chemical industry and other fields. However, its quality and performance are often affected by a variety of factors. In this paper, these influencing factors will be discussed in depth in order to provide useful reference for improving the quality and performance of explosion bonded clad plate.
The selection and pretreatment of raw materials are the primary factors affecting the quality and performance of explosion bonded clad plate. The chemical composition, physical properties and surface state of the raw materials will directly affect the bonding strength of the welding interface and the overall performance of explosion bonded clad plate. Therefore, when selecting raw materials, their applicability and stability should be fully considered to ensure that the quality of raw materials meets relevant standards. At the same time, the appropriate pretreatment of raw materials, such as cleaning, grinding, oil removal, etc., can effectively improve the cleanliness of the welding interface and the bonding quality.
The technical parameters of explosive welding are the key factors affecting the quality and performance of explosion bonded clad plate. Including explosion energy, explosion speed, explosion Angle, welding gap and so on. The reasonable selection and adjustment of these parameters directly affect the shape, structure and performance of the welding interface. The high explosion energy may cause the interface to melt too much and form a brittle phase. The lack of energy may cause the interface to bond poorly. Therefore, in the actual production process, the best process parameters should be determined through testing and optimization according to the specific materials and requirements.
Post-treatment and heat treatment are important means to improve the quality and performance of explosion bonded clad plate. Through appropriate post-treatment, such as cutting, dressing, grinding, etc., defects and residual stresses in the welding process can be eliminated, and the appearance quality and dimensional accuracy of the composite board can be improved. The heat treatment can further improve the strength and toughness of explosion bonded clad plate by adjusting the structure and properties of the material. It should be noted that the temperature and time should be strictly controlled during the post-treatment and heat treatment process to avoid adverse effects on the material.
Environmental factors and operating level are also factors that can not be ignored to affect the quality and performance of explosion bonded clad plate. Environmental factors include temperature, humidity, air pressure, etc. Changes in these conditions may affect the stability and reliability of explosion bonded clad plate. Therefore, environmental factors should be strictly controlled in the production process to ensure that they are within the appropriate range. At the same time, the skill level and experience accumulation of the operator will also have an important impact on the quality of welding. Skilled operators can accurately master welding skills, timely detection and treatment of problems, so as to improve the quality and performance of the composite board.
In summary, there are many factors affecting the quality and performance of explosion bonded clad plate, involving raw materials, process parameters, post-treatment and heat treatment, as well as environment and operation. In the actual production process, these factors should be comprehensively considered, and controlled and optimized through scientific methods and means to improve the quality and performance of explosion bonded clad plate to meet a variety of complex and demanding application needs.
