High Precision Automatic Tube Welding Machine With Orbital Head 380V-440V pipe orbital auto welder
Machine Quick Details:
- Equipment adopts standard modular design,easyreplacement of spare parts, low cost;
- With speed feedback function,make weldingtongs rotation more accurate and stableto-achieve perfect welding quality;
- With automatic arc length and ateral oscillation-function, to meet the welding of pipe fittings ofdif-ferent sizes;
- Welding tongs is water cooled by circulation,hightemporary load ratelong time continuousworkstable and reliable no heat;
- Under the same conditions,with different pipedi-ameters, only need to input pipe diameterswithout adjusting the welding parameters can beweld-ed;
- Welding tongs adopts hafer clamps,which canbeadjusted according to the diameter of the pipe.sothat the welding tongs firmly locks the pipe fit-ting.
Welding head Quick details:
- Automatic all position TIG pipe to pipe welding with/without wire feeding
- Compact structure design, stable rotation with small rotating inertia
- Oscillation, multi-passes welding process
- Suitable for connection of tube to tube, tube to flange, tube to elbow, tube to valve
- Water circuit cooling, achieving long time working
- This machine is modular in design, compact in design and compact in structure.
- The main components are aluminum structure and stepless adjustable clamp to fix the pipe diameter.
- Gapless gear transmission structure design with automatic AVC
