A bench AS333 for TIG welding longitudinal seams of thin-walled tubes.

The outlook of the bench AS333.
    AS333 intends for automatic TIG welding with or without filler wire longitudinal joints of thin-walled tubes from low-alloyed and stainless steels up to 1000 mm long, diameter - 90-600 mm, thickness - 0,5...1,5 mm.
    The bench welds sheet metal as well.

    AS333 consists of:
  1. Frame;
  2. Mechanism of longitudinal moving of the torch;
  3. Tract;
  4. "Key row" mechanism of fixation of welding edges (pneumatic drive);
  5. Mechanisms of torch raising with a manual corrector of its position;
  6. Control system;
  7. Operator console;
  8. Set of welding equipment;
  9. Cooling system;
  10. Pneumoapparatus etc.
  11. Downloud photos of seams. 140 KB.

    AS333 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, high-frequency 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. Continuous adjustment of welding parameters;
  4. Quick bench readjustment to the welded of tubes with different lengths;
  5. There are versions of machine:
    - AS333-500 for tubes up to 500 mm long;
    - AS333-1250, AS333-1500 and AS333-2000 up to 1250, 1500 or 2000 mm long.
  6. The bench can be completed with cold wire feeder UP4 and programmer of seam length.
  7. This bench is an analogue of a bench AS308 for MIG/MAG welding of sidewalls from low-carbon steels;

    Launching:
  1. about 100 benches in 2007 - 2015 at plants of Kiev, Moscow, St.Petersburg, Riga, Kharkov etc.
