Performance features On-line Performance: Good (Designed as per the one line equipment of the production line) Application: broad (pipe and cover welding of various structures of DN≥400 and DN≤800 in various industries). Welding Efficieny: Excellent (100 150 inch/day, which is 4 times higher than the manual welding) Operability: very good (applicable and easy to operate even if you are a new user within a short period of time) Surface finishing: good (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 with friction; the necessary balance weight shall be provided for the pipe with DN≥600 and which the wall thickness is ≥40 to balance the serious eccentricity resulted from bending). Price: a bit higher than the Piping Allposition Automatic Welding Machine (SGW). Technical parameters Pipe diameter applicable: DN200 800(φ219 810) Pipe wall thickness applicable: 18 80MM Materials applicable: carbon steel, alloy steel, stainless steel and cryogenic steel Welding line applicable: various welding lines of tubesections such as tubetube, tube elbow, tubeflange, flangeflange and flangeelbow, etc (a fake pipe transition connection shall be applied if necessary). Driving system: Two rows of metal+ rubber compound idler wheel driven by motor. Clamping system: clamping with double chain clamping mechanism 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: Nil Speedregulation Mode:VF stepless speed control system Control system: a product of our patented technology. Welding mode: thick and single double wire SAW. Welding Power: our OEM products which are famous in China (or as per customers demands)
