A machine AS349 for automatic welding of circular seams of rotatable joints.

    AS349 intends for automatic MIG/MAG welding of circular seams of rotatable joints with horizontal or inclined up to 900 axis of rotation from low-alloyed steels with a diameter 50-300 mm, length - 50-500 mm.

    AS349 consists of:
  1. frame and column for arrangement;
  2. control cabin (inside the column);
  3. operating console;
  4. rotator;
  5. mechanisms of the torch raising;
  6. assembly fixture;
  7. sit of welding equipment;
  8. pneumoapparatus.

  1. Programmed control all mechanisms and devices of the machine, as well as diagnostics of their condition, is realized by the Schneider Electric controller.
  2. Base program ensures: moving the torch in the welding start position, starting of the arc, delay of moving the torch for shaping a puddle, rotating the platen with necessary speed, crater welding, raising the torch and returning the platen on march speed in the source position.
  3. Continuous adjustment of welding parameters.
  4. Quick machine readjustment to the welding of different sizes of details.

  1. One machine in 2008 at "Prompribor", Livly, Russia.
  2. Two machines in 2008 at "Transmash", Belev, Russia.
