Piping Prefabrication Automatic Welding Machine (SAW) ? Model: PPAWM-24B1/B3 ? Performance features ? On-line Performance: Excellent (Designed completely as per the one line equipment of the production line) ? Application: extremely broad (pipe and cover welding of various structures of DN≥150 in various industries). ? Welding Efficieny: Excellent (250～350 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 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). ? Price: a bit higher than the Piping All-position Automatic Welding Machine (FCAW/GMAW). ? Technical parameters ? Pipe diameter applicable: DN50～600(φ60～610) ? Pipe wall thickness applicable: 3～60MM ? Materials applicable: carbon steel, alloy steel, stainless steel and cryogenic steel, etc. ? Welding line applicable: various welding lines 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 three-row stainless steel roller and worm- worm wheel (B1) or driven by two-row rubber roller and reducer (B3) ? Clamping system: the electric clamping arm is adjustable and 180 degree rotational ability; it clamps manually with screw double wheels. A chain tensioner might be equipped if necessary. ? 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: manual cross regulator ? Control system: a product of our patented technology, non～PLC control. ? Welding mode: thin double wire SAW. ? Welding Power: our OEM products which are famous in China (or as per customers’ demands) ?
