Product Overview




1.1.            Application:

    Easy to constitute an automatic circular (straight) seam welding system with proper welding sources and welding guns, to improve welding speed and quality. It’s mainly used in instrument, bellows, medical devices and electronic components and other precision workpeice.

1.2.            Components:

    It main consists of rotary headstock, tailstock, lathe bed, 3-D adjusting mechanism, pneumatic lifter, travel mechanism and PLC controlling system. Combined structure is convenient for installation, and has a good mobility.

1.2.1.      Lathe Bed: With guide rail, and the distance between headstock and tailstock is adjustable.

1.2.2.      Rotary Headstock: Driven by DC gear motor, with stepless speed regulation function and welding current detection switch.

1.2.3.      Tailstock: With hand wheel for imparting motion to lathe center.

1.2.4.      3-D Adjusting Mechanism: Adjust torch position accurately.

1.2.5.      Pneumatic Lifter: Lift up torch automatically.

1.2.6.      Travel Mechanism: Automatic longitudinal seam welding and move carriage.

1.2.7.      Control System: Advanced PLC controlling system, humanized operation interface, high degree automation, stable and reliable performance.

1.3.            Welding Process:

1.3.1.      Welding Mode: torch fixed, workpiece rotating. Automatic welding.

1.3.2.      Welding Method: It can be used with argon arc welding machine (supporting the use of wire feeder), CO2/MAG/MIG welding machine, pulsing welding machine or other welding sources to form an automatic girth (longitudinal) seam welding system.
