A machine AS327 for MIG/MAG welding of longitudinal seams (flame tubes).

    AS327 intends for automatic MIG/MAG welding of longitudinal joints of tubes (flame tubes) from low-alloyed steels by the length up to 400 mm with the thickness 1.2 - 3.0 mm.
    AS327 consists of:
  1. Platform;
  2. Column with a mechanism of a inclination;
  3. Mechanism of longitudinal moving of the torch;
  4. Mechanism of fixation of welding edges (pneumatic drive);
  5. Mechanisms of torch raising with a manual corrector of its position;
  6. Control system;
  7. Operating console;
  8. Set of welding equipment;
  9. Cooling system;
  10. Pneumoapparatus.
The outlook of the machine AS327.

    AS327 peculiarities:
  1. Programmed control all mechanisms and devices of the machine, as well as diagnostics of their condition, is realized by a 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, moving the torch with necessary speed, crater welding, raising of the torch and returning it on march speed in the source position.
  3. It has possibility to preset two and more modes of welding by means of the task board modes for the quick machine readjustment to the welding tubes of different thickness;
  4. Continuous adjustment of welding parameters.
  1. In 2006 two machines on Ukrainian plants.
  2. In 2008 four machines on Ukrainian plants.
