How to use 160mm HDPE pipe hydraulic butt fusion welding machine?

WELPING is going to share with you how to use the 160mm HDPE pipe hydraulic butt fusion welding machine safely to achieve the highest efficiency.

HDPE (High-Density Polyethylene) pipes are widely used in various industries due to their durability, flexibility, and resistance to corrosion. To ensure leak-free joints and secure connections, it is essential to use proper welding techniques. In this blog post, WELPING will guide you through the steps of using a 160mm HDPE pipe hydraulic butt fusion welding machine. By following these instructions carefully, you can achieve reliable and robust joints that meet industry standards.

Step 1: Prepare the Workspace

Before starting the welding process, prepare a clean and organized workspace. Ensure that you have enough room to maneuver the welding machine and align the pipe segments properly. It is crucial to keep the area free from debris, moisture, and any potential sources of ignition.

Step 2: Inspect the Machine and Components

Thoroughly inspect the 160mm HDPE pipe hydraulic butt fusion welding machine and its components before use. Check for any signs of damage, wear, or malfunction. Ensure that the machine is calibrated correctly and the heating plate is clean and in good condition. Verify that all necessary accessories, such as clamps and alignment tools, are present and functioning properly.

Step 3: Measure and Cut the Pipes

Measure and mark the pipes according to the desired joint length. Using a suitable cutting tool, make clean, perpendicular cuts on both pipe ends to ensure proper alignment during the welding process. Remove any burrs or rough edges to achieve a smooth mating surface.

Step 4: Align the Pipes

Align the pipe ends precisely using appropriate alignment tools or clamps. It is essential to align the pipes accurately to ensure a strong and leak-free joint. Take extra care when aligning larger diameter pipes, as any misalignment can lead to weak connections or imperfect fusion.

Step 5: Set the Welding Parameters

Refer to the manufacturer's instructions to set the appropriate welding parameters on the 160mm HDPE pipe hydraulic butt fusion welding machine. These parameters may include welding temperature, pressure, and time based on the pipe diameter and material thickness. Ensure that the machine is properly adjusted to achieve the desired fusion quality.

Step 6: Heat the Pipe Ends

Place the heating plate of the welding machine between the aligned pipe ends and apply even pressure. The heating plate will gradually heat the pipe ends to the required fusion temperature. Maintain the heating time as recommended by the manufacturer to achieve optimal fusion. Avoid overheating the pipes, as it can compromise the integrity of the joint.

Step 7: Remove the Heating Plate

Once the heating process is complete, carefully remove the heating plate from between the pipe ends. Be cautious not to disturb the alignment of the pipes during this step. Keep in mind that the heated pipe ends are extremely hot, so it is essential to use appropriate personal protective equipment, such as heat-resistant gloves and goggles.

Step 8: Fuse and Cool the Pipes

Quickly bring the preheated pipe ends together to fuse them, ensuring proper alignment. Apply controlled pressure using the hydraulic butt fusion welding machine as recommended by the manufacturer. Maintain the pressure for the specified cooling time, allowing the joint to solidify. Resist the temptation to disturb the joint during the cooling process, as it can lead to weak or imperfect fusion.

Step 9: Inspect the Joint

Once the joint has cooled down, carefully inspect it for any irregularities, such as voids, bubbles, or signs of incomplete fusion. Any defects should be remedied immediately by repeating the fusion process or addressing the potential causes of the flaws. A thorough inspection is crucial to ensure the joint's integrity and long-term reliability.


Using a 160mm HDPE pipe hydraulic butt fusion welding machine requires careful preparation, precise alignment, and adherence to the manufacturer's instructions. By following the steps outlined in this blog post, you can achieve strong and durable joints that meet the standards of quality and reliability expected in various industries.
