1. Construction preparation: check the specifications and materials of pipes and electrofusion pipe fittings to ensure that the electrofusion welding machine works normally and the parameters are accurate.
2. Pipeline treatment: cut the pipe, the end face is smooth and free of burrs, oil and impurities, and the insertion depth is measured and marked.
3.Preparation of pipe fittings: check that there is no damage to the appearance of electrofusion pipe fittings, and clean the connection parts.
4. Connection operation: insert the pipe into the pipe fitting to the mark, and use the electrofusion welding machine to weld according to the specified parameters, and there is no external force interference during welding and cooling.
5. Quality inspection: After cooling, check that there are no defects in the appearance of the weld, and conduct pressure tests to ensure the tightness and strength.
