Material Preparation: Place the pipeline or fitting on a flat surface, set it on the joining machine, and ensure there is a sufficient cutting allowance of 10-20mm.

2. Cutting: Remove impurities and oxidation layers from the welded pipe sections and end faces of pipe fittings to ensure that the mating end faces are flat, smooth, and free of impurities.

Three: For the two welded pipe sections, the end faces must be perfectly centered. The smaller the misalignment, the better. The misalignment cannot exceed 10% of the wall thickness. Otherwise, it will affect the quality of the joint.

4. Heating: The recommended temperature range for bonding is typically between 210-230°C. The heating plate's heating time varies with seasons, aiming for a melt length of 1-2mm on both ends.

5. Melted Joining: A critical aspect of welding, the joining process should always be conducted under melted pressure, with a flange width of 2-4mm being ideal.

6. Cooling: Maintain the same pressure at the interface and allow the connection to cool down slowly. The cooling time should be sufficient until the edges feel stiff to the touch and no heat can be felt.

7. Alignment Completed: After the cooling is done, release the kawa, remove the alignment machine, and prepare for the next interface connection.
