Last week, our team conducted a welding test on a large-diameter PE pipe using the FX630 butt fusion welding machine in our factory workshop. The purpose of this test was to verify the machine’s performance on thick-wall pipes and to document the full welding process for future reference and customer demonstration.
We began by placing the large PE pipe into the clamps of the FX630 main frame, installing the appropriate clamp inserts, and adjusting the position to keep the pipe aligned on the center axis.
Once clamped, the pipe remained stable—an essential foundation for the upcoming facing and heating steps.
Using the crane, the facer was lowered into working position and activated.
The facing process ensured:
· Smooth and level pipe ends
· Removal of the oxidized surface layer
· Clean and uniform contact surfaces for heating
After facing, the shavings were cleaned immediately, leaving a neat and ready-to-heat pipe surface.
When the temperature controller on the hydraulic unit reached 220°C, the heating plate was placed between the pipe ends to begin the heating phase.
Because the pipe had a large diameter and thick wall, the heating time for this test was approximately ten minutes.
Throughout heating, the operators checked temperature stability and surface contact to ensure even heating.
At the end of the heating cycle, the heater was removed quickly and smoothly.
The two molten pipe ends were then brought together under controlled hydraulic pressure to complete the fusion.
The movement was stable, and the bead formed evenly along the joint.
After cooling, the weld was inspected visually. The results showed:
A symmetrical, well-formed bead
No noticeable misalignment
A clean and stable joint appearance
The FX630 delivered the expected welding performance for large-diameter PE pipe applications.
This welding test provided a clear demonstration of the FX630 operating under practical conditions and handling thick-wall pipe welding effectively.
