The development history of flash butt welding machine-Xinxing Welding
Release time:2022.01.26
Summary of information:
Flash butt welding machine appeared together with resistance welding technology. It has gone through extensive type to advanced hydraulic type. Let’s take a look at it together.
Flash butt welding technology and resistance welding technology appeared almost at the same time. American Professor Thomson obtained a patent for resistance butt welding in 1885, which was the earliest record related to resistance welding.
1886Resistance butt welding machineappear. The Germans first used flash butt welding machines in 1903. From the 1950s to the 1970s, the former Soviet Union, the United States, Germany, Japan, Switzerland and some other countries did a lot of work on the basic theory of flash welding and the development of flash butt welding machines, which led to the rapid development of flash welding technology.
In terms of feeding control of workpieces, the earliest manual levers and pneumatic cams gradually transitioned to hydraulic system control; in terms of voltage control methods, they evolved from chip-type and blade-type gear series converters, to mercury ignition tubes, and then to thyristors.
The power supply waveform of flash welding has evolved from traditional single-phase AC to medium-frequency DC.
In terms of welding machine capacity, some large-capacity flash welding machines that can weld large-section workpieces have also been developed. In the 1960s and 1970s, the large-scale flash welding machine produced by the original West German company had a power of 4X 103 kw, an upsetting force of 700t, and a weldable cross-sectional area of 1X 105 mm2; the 3X 103 kW thin plate flash butt welding machine produced in Japan could weld steel plates with a width of 1800 mm and a thickness of 6.5 mm.
With the development of industry, the application range of flash butt welding continues to expand, and the cross-section of the welding workpiece is getting larger and larger. As the welding cross-section increases, the required capacity of the welding machine increases. In order to save power and meet the needs of flash welding of large-section workpieces, some foreign research institutions have conducted a series of studies on the flash welding process and created two new methods of program-controlled reduced voltage flash butt welding and pulse flash welding.
In recent years, my country's flash welding technology has also developed rapidly. The method of controlling voltage has developed to thyristor control; the power supply waveform of flash welding has developed from traditional single-phase AC to medium frequency DC. The application scope of flash welding continues to expand, and the capacity of welding machines continues to increase.
Now, computer technology has also begun to be applied to flash welding process control and parameter monitoring. The use of flash welding technology to ensure the continuous production of plates (strips), bars and pipes to achieve higher product quality and production efficiency is currently the most advanced processing technology in the international metallurgical industry. Since flash welding is a welding between base metals, it ensures that the structure and degree of the weld and the base metal are close to each other, and a high-quality joint with almost the same performance as the base metal can be obtained. It is the best choice for many enterprises.
