Welding technology has been widely used in the machine tool industry. Welding technology has gradually developed into the leading process in the machine tool industry, which is mainly reflected in the following aspects: first, some backbone enterprises have established welding workshops or metal structure plants with a certain scale, established a complete welding management system, and absorbed and digested the welding process standards of imported products. Welding technology has gradually developed into the leading process in the machine tool industry, which is mainly reflected in the following aspects: first, some backbone enterprises have established a certain scale of welding workshops or metal structure factories, limited materials and their limits, established a complete welding management system, and absorbed and digested the welding process standards of imported products. Second, the welding process flow has been improved from a single processing process to a set of emerging comprehensive engineering technologies from raw material pretreatment, cutting and blanking, forming, welding, post welding inspection and post welding treatment. Third, CNC precision cutting and computer programming nesting technology have been applied. Fourth, CO2 gas and argon rich gas shielded welding or submerged arc welding and other high-precision, advanced and efficient new processes have been promoted and applied. Fifth, X-ray flaw detection and ultrasonic nondestructive testing are widely used to stabilize the internal quality of welds. Fifthly, the new technology of vibration aging is popularized, which achieves the purpose of reducing and homogenizing the residual stress of the welded structure, reduces the deformation of the weldment, and stabilizes the accuracy

at present, the main welding technologies applied in the machine tool industry include the following aspects: the application of steel plate pretreatment technology; Application of NC cutting technology; Application of high efficiency welding technology such as gas shielded welding. Among them, gas shielded welding and other high-efficiency welding technologies have been widely used in machine tool bed, gears, eccentric bodies, rocker shafts, cylinder bodies, pipe flanges and covers that are not processed after welding, and have become one of the main welding processes in the machine tool industry

although the numerical control rate of the output of China's machine tool industry has increased, the overall numerical control rate is still low, and there is still much room for improvement compared with the level of about 70% in developed countries. It is believed that with the continuous structural adjustment in China, these two different concepts will increase, and the numerical control rate of China's machine tools will significantly increase

the welding structure of machine tool products is more and more used in various fields. Now the development trend of machine tool manufacturing industry has gradually changed. By the end of 2014, welding has replaced casting, welding has replaced forging, and welding has replaced cutting. Machine tool manufacturing industry has long been inseparable from welding process. With the maturity of technology and the development of machine tool industry, welding technology is also developing in the direction of high efficiency, high quality, numerical control and automation, and the welding process will be more developed in the future
