Before welding, it should be checked whether the pipe mouth makes a right angle with its own axis. If there is no right angle, its mouth should be cut and it should be made to form a right angle with its own axis.
• The pipe surface to which the electrofusion coupling will be attached should be marked. Weld length should generally be half of the sleeve length. The marked cut should be excavated with the scraping apparatus in such a way that it will not oxidize.
• After scraping, it should never be touched and protected from adverse weather conditions. The coupling is attached to the pipe, and if necessary, the system is fixed with a clamp.
• The cables on the electrofusion welding machine are plugged into the sockets on the sleeve. The barcode value on the cuff is entered on the machine. Then, welding is performed by applying tension to the coupling socket ends. In order to remove the clamps, the cooling process is expected to take place.
• Labor is a more important issue than the quality of the pipe in the laying process of polyethylene pipes. In particular, the certificate and reference of the welder who will perform the welding process is important, but it should also be audited.
