Numerical control development of welding technology in machine tool industry

the welding structure of machine tool products is more and more applied. Welding instead of casting, welding instead of forging, and welding instead of cutting have become the general development trend of machine tool manufacturing industry. Machine tool manufacturing is inseparable from welding. At present, the welding technology in the machine tool industry is also developing in the direction of high efficiency, NC, automatic archiving after g. test, manual archiving and automation

the welding structure of machine tool products is more and more used. Welding instead of casting, welding instead of forging, and welding instead of cutting have become the general development trend of machine tool manufacturing industry. Machine tool manufacturing is inseparable from welding. At present, welding technology in machine tool industry is also developing towards high efficiency, numerical control and automation

in the machine tool industry, the development of welding technology is developed with the application of welding structure of machine tool products. Metal cutting machine tools, forging machinery and casting machinery products are the main application fields of welding technology 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: (1) 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 standard with an average annual gross profit of 168million yuan. (2) The welding process flow has been improved from a single processing process to a set of emerging comprehensive engineering technologies, such as raw material pretreatment, cutting and blanking, forming, welding, post welding inspection and post welding treatment. (3) Numerical control precision cutting and computer programming nesting technology have been applied. (4) Advanced and efficient new processes such as CO2 gas and argon rich gas shielded welding or submerged arc welding have been popularized and applied. (5) X-ray flaw detection and ultrasonic nondestructive testing are widely used to stabilize the internal quality of the weld. (6) The new VSR process is popularized to reduce and homogenize the residual stress of welded structure, reduce the deformation of welded parts and stabilize 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, high-efficiency welding technologies such as gas shielded welding to turn on the oil pump (note that the electromechanical machine should rotate clockwise at present) have been widely used in machine tool bed, gear, eccentric body, rocker shaft, cylinder body, pipeline flange and cover that are not processed after welding, and have become one of the main welding processes in the machine tool industry

with the increasing application of welding structure of machine tool products, it has become the general development trend of machine tool manufacturing industry to substitute welding for casting, welding for forging and welding for cutting. Machine tool manufacturing is inseparable from welding. At present, welding technology in machine tool industry is also developing towards high efficiency, numerical control and automation

although the NC rate of output in China's machine tool industry has increased, the overall NC rate is still low, and there is still much room for improvement compared with the level of about 70% in developed countries. Luobaihui believes that with the continuous increase of structural adjustment in China, the CNC rate of machine tools in China will be significantly improved
