Press Roller Type Automatic Pipe Welding Machine (PPAW / PPBW Series)

WINCOO ENGINEERING CO.,LTD's PPAW/PPBW press roller type automatic pipe welding machine is the core welding station of a modern pipe spool fabrication line. It automatically welds pipe-to-pipe and pipe-to-fitting butt joints (flange, elbow, tee, reducer) with single-side welding and double-side formation, delivering RT/UT qualification rates above 98% while dramatically reducing dependence on skilled manual welders.

Product Overview

The press roller type automatic pipe welding machine rotates the assembled pipe spool on precision polyurethane drive rollers while a column-and-cantilever welding head travels along a linear guide rail, keeping the torch at the optimum welding position throughout the entire circumference. The result is a uniform, aesthetically perfect weld bead — pass after pass, spool after spool — without rotating the workpiece in a chuck.

The machine supports TIG, hot-wire TIG, CO2/MIG/MAG and fine-wire submerged arc welding (SAW), which means one workstation can handle automatic root pass, filling and cap welding of carbon steel, alloy steel, stainless steel and low-temperature steel pipes across the full range of a piping prefabrication workshop.

Key Specification

Core Features

Multi-Process Capability on One Station Configure TIG, hot-wire TIG, CO2/MIG/MAG or fine-wire SAW — singly or in combination — to realize automatic root pass, filling and cap welding. Hot-wire TIG (WINCOO's proprietary system) achieves more than twice the deposition rate of cold-wire TIG.

Roller-Drive Rotational Welding The fitted spool is rolled onto the press-roller drive unit; precision gear reducer with turbo-worm transmission rotates the pipe smoothly and stably. Roller rotation speed is steplessly adjustable via frequency converter to match different diameters and wall thicknesses.

CNC Linear Oscillation Imported closed-structure CNC oscillators (stepping motor + high-precision ball screw + imported linear guide rail) produce even weld ripple with adjustable swing width (max 30 mm), frequency (20–60 times/min) and left/right dwell time (0–3 s) for beautiful weld appearance.

WSP Pipe Welding Expert Control System PLC + touch-screen HMI (WEINVIEW) integrates all process parameters with a built-in welding parameter database. Operators with no welding experience can master the machine within 2–3 days of training.

International Brand Components Lincoln Flextec 650 multi-process welding power source, Delta PLC/inverter, Schneider switches, WEINVIEW touch screen, TBI linear guides — CE, ASME and HSE compliant design.

Wide Joint Coverage Automatic butt welding of pipe + pipe, pipe + taper pipe, pipe + flange, pipe + elbow and pipe + tee — the full spool joint portfolio of a pipe fabrication line.

Applications in the Pipe Spool Fabrication Line

The PPAW/PPBW series is a drop-in welding station between the fitting-up (tack weld) station and downstream QC in the WINCOO pipe spool prefabrication line:

Cutting & Beveling → Multi-Function Fitting-Up → Pipe Welding Machine → Inspection & Delivery

Typical industries:

• Oil & gas and petrochemical piping prefabrication

• Shipbuilding and offshore module fabrication

• Power plant (thermal & nuclear) process piping

• Boiler and pressure vessel pipe systems

• Steel structure and general piping workshops

Why Choose WINCOO

• Proven in international projects — delivered to fabricators in Indonesia, the UAE and beyond with FOB Shanghai / CFR terms and 12-month warranty

• Rapid ROI — automatic welding raises output 3–4 times over manual methods and reduces the need for certified manual welders

• Simplified operation — presets and one-touch parameter recall; zero-experience operators learn in days

• Complete line supply — WINCOO provides the full pipe prefabrication line (cutting, fitting-up, welding, conveying), not just a single machine
