      Solid State High Frequency Welder

      High frequency welders are used for manufacturing welded steel tubes, pipe and structural squares, and rectangular tubes. These welders are installed inline on a tube mill and are used to weld the open edge seam after it has been formed from a flat strip in the tube mill.

      Welding is continuous to up to hundreds of feet per minute and operates uses high frequency sound waves (heat energy). These high frequency sound waves are concentrated on the open edges of the formed tube until the tube is red hot and forced together via a series of rolls to form the welded seam.

      Composition

      The solid state high frequency welder is composed of the rectifying cabinet, inverter and output cabinet, connecting optical fiber, closed loop water cooling system, central operator console, and mechanical adjustment device.

      Characteristics
      • Designed with simple electrical circuit, the solid state high frequency welder is easy to install. With complete protection, it is easy to maintain.
      • It produces very little noise and less pollution to an electric network.
      • Without high pressure, the welder is safe to use.
      • The welding equipment achieves a maximum efficiency of more than 85%, thus saving energy and requires less cooling water.
      • High reliability and stable operation.
      • Easy to maintain, users can repair it on their own.
      • With necessary equipment, the welder is able to be used at the rated power.
      • The control apparatus are universal and require no adjustment.
