Steel maintenance _ Peng Jian Steel (certified) _ Steel Ltd., Huizhou, Dongguan City, Peng was built by steel. Steel Co., Ltd., Dongguan City, Peng Jian (dgpengjian.cn) is specialized in the "Steel" of the enterprise, the company adhering to the "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Xu. High-frequency welding H-beam using high-frequency current local heating of the metal surface, making welding under loads, do not use any wire, flux, continuous mass production. 1. The cross-sectional dimensions of the advantages of high accuracy due to the use of high-quality steel coils, precision-sectional shape after welding fine, so that the structure of the assembly easier. 2. The cross section of the flange plate and the excellent performance of the web thickness ratio can be increased relative to the rolling steel than in the same weight can be made greater flexural properties of steel products, higher performance components cross-section; in the same cross-sectional performance, component lighter 3. sectional dimensions can be customized extensive use of case, you can. according to user-specified cross-sectional dimension metallurgical production. 4. Welding web site performance homogeneous material with uniform tissue fusion flange plate material. Remedy steel fatigue damage of such technical devices with small size, high frequency, In the manufacturing and assembly of steel bridge can be used to facilitate other characteristics, and therefore should be introduced in the production of steel bridges. Its top most used is tempered T Arts, the upcoming high-temperature furnace components into the overall heating, usually heated to 600 to 800. To overcome the above process method and process measures of disadvantage in steel bridges in the development of a device known as a high-frequency ultrasonic impact technology. But when the energy input has not reached the appropriate magnitude, reducing the residual stress effect is not significant steel structure maintenance, and therefore, of course, currently used in the high frequency vibrator excitation power supply technology has been very mature, and its small size, higher frequencies, but it is a low energy input, and therefore can only be used for this mature vibrator provided under laboratory spectral analysis of the structure of the vibration noise. Because standard finite steel high-frequency vibration table, so the standard is not only a member of this approach. In some metal processing and manufacturing, processing and assembly of precision because some to be part of the growing progress, reducing component residual stress, improve member service life demands more urgent, in order to develop a technique called high-speed shot, the effect is very obviously steel prices, could significantly advances tired performance capability and resistance to stress corrosion and get a wide range of applications. However, the low frequency of the manual percussion, the energy input to the structure is limited, so the effect is not obvious. Difficulty of this method is that both require the weld zone in the structure of the size of the vibrator, and the required high quality and sufficient effect of the frequency of vibration, due to the metal structure of the input energy in the actuator 43 with the vibrator quality and the role of frequency squared proportional to the product. Because the average overall process of heating and cooling structural deformation, so that the local high residual stress and strain to get loose. Large members, this method requires a large standard high temperature heating apparatus, so that standard components can be processed is limited by the actual heating device for the equipment.
