The core of electrofusion welding lies in "cleaning, scraping, alignment, fixing, and cooling." Among these, scraping off the oxide layer is the most critical step.
A special scraper must be used to completely remove the oxide layer (approximately 0.1-0.2mm thick) from the welding area of the pipe until fresh material is exposed.
Touching the scraped surface with bare hands is strictly prohibited to prevent secondary contamination.
Secondly, before assembly, the insertion depth must be accurately marked on the pipe, and special clamps should be used to secure the pipe and fitting, ensuring they are concentric and gap-free.
Finally, during the welding and natural cooling periods, it is absolutely forbidden to move the fitting, apply external force, or use water cooling, as this may cause internal stress or cold welding.
