Thick-wall Piping Automatic Welding Machine (SAW)

Characteristics:
1. On-line performance: Excellent (designed for flow process)
2. Application: Used in screen welding (DN≥400 or DN≤800)
3. Welding capacity: Excellent (100-150 inch/day, which is over 4 times of manual welding)
4. Operability: Good (easy to operate even if you are a fresher)
5. Surface forming: Excellent (the welding gun will always be positioned in optimum position)
6. Welding qualification ratio: ≥98%
7. Driving reliability: Good (driven by frictional force, however, it is required to set essential balance weight to offset large bending moment caused by elbows for pipeline: DN≥600 and diameter≥40)
8. Price: Much higher than the automatic pipe welding machines-submerged arc welding

Technical parameter
1. Pipe diameter: DN400-800(φ426-810)
2. Pipe thickness: 18-80MM
3. Pipe materials: carbon steel, alloy steel, stainless steel and cryogenic steel.
4. Welding: tube-tube, pipe-pipe, tube-elbow, tube-flange, flange-flange, flange- elbow (dummy tubes for connection when necessary).
5. Driving system: motor drive with two-row metal rubber roller.
6. Compression system: compressed firmly by manual double-chain Leading-Screw.
7. Bracket system: Separate type of trolley matching for welding machine, which may be adjusted along the track according to the length of the pipeline.
8. Counterweight system: no Counterweight
9. Speed-regulation mode: Variable-frequency stepless speed control system
10. Adjustment mode: manual cross regulator / electric cross regulator.
11. Control system: products of proprietary technologies owned by our company
12. Welding mode: Thick electrode arc welding
13. Welding power: OEM (or as per customers' demands)
