The so-called "solid state high frequency" is because it uses transistors(MOS field effect transistors or IGBT)as the main inverter components.Unlike vacuum tubes are hollow(interior is full of noble gas,so can be called "gaseous"),transistors are solid.
Read More20 years ago,high-frequency power sources(commonly known as “high-frequency furnaces”)used for welding pipes and heat treatment in China were mainly equipment with electronic tubes(also known as “vacuum tubes”) as the main inverter components.
Read MoreIn today's highly competitive manufacturing industry, solid-state high-frequency welder technology is revolutionizing the way industries produce robust and reliable steel pipes, eliminating the risks associated with complex and high-pressure traditional systems.
Read MoreStanding at a desk piled high with test reports, Wang Jianjun opened a yellowed notebook, which contained the parameters of the first-generation high-frequency welded pipe machine that he had recorded twenty years ago. At that time, we couldn't even afford temperature sensors. We had to rely on the ......
