Overview of Welding Technology
1. Definition and classification of welding
Welding is a process in which two or more metallic (or non-metallic) materials are joined together by heat or pressure. According to the way of heating during the welding process, welding method, welding material and other factors, welding can be divided into various types, such as gas shielded welding, arc welding, resistance welding, laser welding, electron beam welding and so on.
2. Development history of welding technology
From the ancient copper welding and iron welding to the gas-shielded welding and electric arc welding at the beginning of the 20th century, welding technology has experienced a long process of development. With the progress of science and technology, welding technology is also constantly innovating. In recent years, advanced technologies such as laser welding, robot welding and digital welding have gradually become the research hotspots in the field of welding.
3. Status of application of welding technology in China
In China, welding technology has been widely used. In the automobile, ship, steel, aerospace and other industries, welding technology plays a vital role. Taking automobile manufacturing as an example, welding quality directly affects the safety performance and durability of automobiles. Therefore, China attaches great importance to the research and application of welding technology. At present, China has mastered a variety of advanced welding technologies, such as laser welding, robotic welding, etc. These technologies have achieved remarkable results in improving production efficiency, reducing production costs and improving product quality. However, compared with the international advanced level, China in the field of welding technology there are still some gaps, it is urgent to increase research and development efforts to catch up.
With the continuous innovation of welding technology, more and more black technology began to emerge in the welding industry. Next, we will discuss these black technology, and analyze their application prospects in the field of welding in China.
