PPEW Series
WINCOO
Where long-pipe stations rely on roller drives, the PPEW series clamps the workpiece directly in a rotating through-hole chuck. Because the pipe end is positively gripped, there is zero axial creep during welding — critical for short spools and flange joints where run-out would otherwise cause weld defects. The chuck can be tilted 0–90° for inclined flange fillet welding, and the hollow spindle (Φ360 mm bore) lets pipes pass through for extended-length welding when needed.
The machine is delivered with either pulsed MIG or hot-wire TIG automatic welding systems (Aotai power sources), and is engineered for stainless steel, carbon steel and alloy steel short-pipe fabrication.

Zero Run-Out Chuck Clamping The workpiece end is firmly gripped in the three-jaw through-hole chuck — no axial movement during welding, ensuring consistent root gap and perfect bead formation on short spools.
0–90° Tilt for Flange Fillet Welding The chuck positioner tilts electrically for inclined flange fillet welding with ±45° torch oscillation, producing clean, evenly formed fillet welds that meet corner-weld height and pressure-test requirements.
Precision Arc Length Tracking (AVC) A precision arc sensor plus WINCOO's proprietary control technology automatically adjusts torch height to compensate for pipe ovality and non-standard grooves — a key factor in raising welding qualification rates on thin-wall stainless work.
Hot-Wire TIG Option The hot-wire TIG system more than doubles the deposition rate of conventional cold-wire TIG, cutting cycle time on stainless steel spools dramatically while preserving TIG bead quality.
One-Touch Operation Preset welding programs in the PLC + touch-screen WPS expert system mean unskilled operators master the machine in 1–2 days of training. Multi-layer multi-pass welding runs continuously in automatic mode.
Corrosion-Resistant Engineering Aerospace aluminum alloy closed oscillators prevent dust and fume ingress; all pipe-contact parts are coated, stainless steel or blackened to avoid carbon pollution of stainless steel workpieces.
Short pipe spool and fitting prefabrication (flange + pipe + flange, elbow + pipe + elbow)
Pipe-to-fitting and fitting-to-fitting automatic TIG welding
Inclined flange fillet welding in pipe fabrication lines
Stainless steel and alloy steel process piping for food, pharmaceutical, chemical and semiconductor plants
Compact welding cells where floor space is limited
The PPEW-24 slots into the WINCOO pipe spool fabrication line as the short-spool / fitting welding station, complementing long-pipe roller-type stations and the multi-function fitting-up center:
Cutting → Fitting-Up → PPEW Short-Pipe Welding → Long-Pipe Welding Station → QC
All stations share the same WSP expert control philosophy, so operators trained on one WINCOO machine can run the entire line.
WINCOO ENGINEERING CO.,LTD designs, manufactures and commissions the PPEW series as a standalone station or as part of a complete pipe prefabrication line.
