The working principle and application area of high frequency pipe welding machine
High frequency pipe welding machine is a kind of equipment specially used for producing welded pipes, using high frequency current for heating and welding of pipes. Working principle: The high frequency machine converts the power supply into high frequency current through high frequency signal, then the current flows through the transmission coil to produce electromagnetic field, which in turn produces induction current to cause local heating inside the steel pipe and weld the pipe through mechanical pressure.
High frequency pipe welding machine is mainly used in construction, petrochemical, automotive, machinery, aerospace and other industries. In the construction industry, high frequency pipe welding machine is often used to produce large pipes. In the petrochemical industry, high frequency pipe welding machine is often used to produce chemical pipes, while in the automotive, machinery, aerospace and other industries, high frequency pipe welding machine is used to produce various pipes and parts.
When welding steel pipes, it is crucial to choose the right high frequency pipe welding machine, not only to improve production efficiency, but also to ensure the quality of welding. The following are a few key points in choosing a high-frequency pipe welding machine:
According to the diameter of the welded pipe to choose the model, the model and the diameter of the steel pipe is generally proportional relationship.
According to the thickness and material selection of power and frequency, the greater the power, the higher the frequency for thicker steel pipes, and moderate power, moderate frequency is suitable for the production of thin-walled steel pipes.
Understand the length of the pipe and equipment adjustment time, the greater the length of the pipe, the longer the adjustment time, so in the selection of the machine needs to be considered according to the actual situation.
Selecting the right high-frequency pipe welding machine is very important, only by choosing high-quality equipment can provide a more stable and reliable production process, improve production efficiency, reduce production costs and losses, and better develop and use the various advantages of steel pipe processing.
The principle of high-frequency pipe welding machine is to melt the metal plate under the action of high-frequency power supply through frictional heat or resistance heating, and then make contact with the metal plate through external force to achieve the effect of fusion after energization. Its produced pipe has smooth surface and stable quality, which is favored by many enterprises.
The application of high frequency pipe welding machine is wide, covering construction, manufacturing, transportation and many other fields, such as manufacturing water supply pipeline, natural gas pipeline, oil and gas pipeline and steam, automobile manufacturing and other industries, all need to use high frequency pipe welding machine for production.
