Solid State High Frequency Welder

Today, high frequency (HF) welding technology has been widely applied in tube mill line for tube welding process. We provide Solid state HF induction welders that ensure a good welding integrity for the end product to survive and meet quality standards in its final application or fabrication requirements.The working principle behind HF induction welding is not that complicated. An induction coil connected to high frequency power supply encompasses the formed tube profile, to induce a high frequency current in the pipe profile. Leveraging the skin effect and proximity effect of high frequency current, the induced electricity is concentrated onto the bonding surface of the tube profile fringe. The resistance of metal itself heats up the profile fringe quickly up to welding temperature. The heated fringe are pressed together and welded by squeezing rolls. The high frequency welder offered by TGMCO is armed with a complete automation control system. With advanced PLC processing technology, the machine enable a smooth adjustment in stepless mode, output power in a wide range, as well as stabilizing the voltage of main circuit by closed loop feedback control. The current overload is monitored constantly with PLC to ensure a reliable protection.
