Welding is a kind of processing technology and connection mode to use the heating, pressure, or the heating and pressure together, then makes the same or the opposite property atoms combined together. Welding have very wide applications in many industries, it can not only be used for metal, but also can be used for nonmetal. Welding technology is mainly used in metal mother material, the commonly used method has electric arc welding, argon arc welding, CO2 protection welding, oxygen welding, acetylene welding, laser welding, electric pressure welding slag and so on. The nonmetal and plastic material can also be used for welding. The metal welding methods have totally more than 40 kinds, they are mainly divided into welded, bonding and brazing three categories. The electric welding is to heat the interface to a melting state in the welding process, do not add any pressure to complete the welding. When welding, the heat source will stay welding workpiece rapidly melting at the two heating interface, form into a melting pool. Molten pool move forward with heat source on the pool, after cooling it will form a continuous seam and the two workpiece connection will become one. In the process of welding, if atmospheric directly contact with the high temperature molten pool, the oxygen in the atmosphere will metal oxide and various alloy elements. The nitrogen in the atmosphere steam into the pool, it will later form into gas hole, slag, crack and other defects in the process of cooling in welding, so that the weld quality and performance is affected. So the Welding And Fabrication technology play a very important role in the development of modern industry.
Material Choice of Aerospace Components
In recent years, with the rapid development of the aerospace industry in our country, the industry that are engaged in the manufacturing of Aerospace Components is increasing day by day. Since the aerospace components are used in the spaceships or planes, so the quality of the all the components must meet the requirements. Usually the choice of material for aerospace components are should be very strict. From the very small screw to the large steel board, all aerospace components should be supplied from the normal manufacturers specializing in the producing of parts for aerospace use. As we all know that Foshan is a famous metal city, it has the name of"the First Aluminum City in China", and at the same time, it is also famous for the large aerospace components enterprise. In the aerospace components, alumium is the most widely used material in the manufacturing of aerospace components due to its special performance that many other metals don't have.
Good Vision for Precision Components
Hardware accessories is always one of the necessary equipments in daily life. We have to use various hardwares almost every day. But as for those hardware specially for certain professional fields. For example, the precision components and fixtures for industries such as solar energy, electronics, optical-communication, medical equipment and office automation. With the rapid development of China's industry and economy, we can expect a bright future in the field of precision components.
