Welding Machine

Product Overview

The Semi-Automatic Hydraulic Butt Fusion Machine is designed for welding HDPE and PE pipes in the diameter range of 40mm to 355mm. This Semi-Automatic Hydraulic Butt Fusion Machine combines a hydraulic pressure system with semi-automatic control, delivering consistent fusion pressure up to 6.3MPa for reliable butt-welded joints in water, gas, and industrial pipeline applications.

Available in BGS160, BGS250, BGS315, and BGS355 models, the Semi-Automatic Hydraulic Butt Fusion Machine features a hot plate with 1-4KW heating power, a planning tool with 0.7-1.1KW motor, and a hydraulic oil pump system. The machine maintains fusion temperature accuracy within ±5°C, ensuring weld quality across different PE pipe grades and wall thicknesses.

Key Features

Four Model Coverage – The Semi-Automatic Hydraulic Butt Fusion Machine series covers 40-355mm pipe diameters across BGS160/250/315/355 models, supporting most medium-diameter pipeline projects with one machine platform.
Hydraulic Pressure System – Integrated hydraulic pump delivers adjustable fusion pressure up to 6.3MPa, providing consistent and repeatable welding force without manual cranking effort.
Adjustable Heater Power – Hot plate output ranges from 1KW to 4KW depending on model, matching the heating requirements of different pipe diameters and wall thicknesses.
Temperature Accuracy ±5°C – Precise thermostatic control maintains hot plate temperature within ±5°C across the fusion surface, preventing overheating or underheating of pipe ends.
Planning Tool Integration – Built-in 0.7-1.1KW milling cutter prepares pipe ends with a single pass, removing oxidation and ensuring flat, clean fusion surfaces.
Portable Hydraulic Unit – Despite weighing 110-240KG depending on model, the Semi-Automatic Hydraulic Butt Fusion Machine features a wheeled frame design for repositioning along the pipeline trench.

Production

Raw Material

The Semi-Automatic Hydraulic Butt Fusion Machine frame is constructed from welded structural steel tubing with powder coat finish for outdoor durability. The hot plate core is cast aluminum with machined flat surfaces and PTFE coating. Hydraulic cylinders use chrome-plated steel rods with NBR seals rated for continuous 6.3MPa operation.

Molding Process

Steel frame components are laser-cut from cold-rolled steel sheet and MIG-welded with robotic welders for consistent joint quality. The hot plate undergoes surface milling to achieve flatness tolerance of 0.05mm. Hydraulic cylinder bores are honed to Ra 0.4 surface finish for smooth pressure application.

Quality Control

Each Semi-Automatic Hydraulic Butt Fusion Machine is pressure-tested at maximum 6.3MPa hydraulic load for 30 minutes without pressure drop. Hot plate temperature uniformity is measured at 9 points across the surface. The planning tool is verified for cutting flatness on SDR11 PE100 pipe samples. Final QC includes a full butt fusion weld test and peel test.
