Automatic Welding Machine for Piping Spool Prefabrication (TIG+MIG/FCAW)
Model: PFAWM-16Ad/24Ad/32Ad/40Ad/48Ad/60Ad
Performance features
On-line Performance: Excellent (Designed completely as per the on line equipment of the production line)
Application: Backing welding or welding the pipes or the cover of the aluminum alloy pipe which need higher quality.
Welding Capacity: High (150-350 inch/day, which is 4 times higher than the manual welding)
Operability: Good (applicable and easy to operate even if you are a new user & accept training within a short period of time).
Surface finishing: Excellent (the welding gun will always be positioned in the optimum position)
Welding compliance rate: 98% min (without re-working for the skilled operator).
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 large diameter pipe, or providing a chain tensioner to improve the reliability of the driving).
Technical parameters
Pipe diameter applicable: DN50-400 (φ60-426mm) / DN100-600 (φ114-630mm)/ DN200-800(φ219-830mm); DN400-1000 (φ406-1016); DN600-1200 (φ610-1219); DN800-1500 (φ813-1524) Or custom made acc to requirements
Pipe wall thickness applicable: 3-30mm (or as per request)
Materials applicable: Carbon steel, alloy steel, stainless steel and cryogenic steel, etc.
Welds applicable: Various butt welding seams of spool pieces such as pipe-pipe, pipe-elbow, pipe-flange, flange-flange and flange-elbow, etc (a fake pipe transition connection shall be applied if necessary).
Driving System: Driven by two line rubber roller and reducer
Clamping system: Clamping arm move up & down electrically and clamps by screw with telescope boom.
Bracket System: Separate type of trolley matching for welding machine, which may be adjusted along the track according to the length of the pipeline.
Counterweight System: No Counterweight
Speed-regulation Mode: VF stepless speed control system
Adjustment Mode: With electric cross regulator
Oscillating system: A product of our patented technology, driven by step motor.
Control system: A product of our patented technology, PLC control.
Welding procedure: TIG+MIG (To be done root pass, filling & final welding)
Welding power: With Lincoln Welding Power Source (or as per customers' dema
