This morning, we had an urgent call from a customer out on site, wanting to double check the weld time for a 63mm electrofusion socket as he was surprised it only takes 65-70 seconds. Best to double check we say, so off we went out to the warehouse to check an EF socket on the shelf. Sure enough, 65 seconds is all it requires.
This of course varies for different sized sockets so the best way to check is on the barcode of the EF fitting itself, which is following the manufacturers’ recommendation.
Barcode Interpretation for Electrofusion Poly Welding
The barcode has 24 numbers in it, most of which can be interpreted by using an industry wide method.

The Purpose of a Barcode
In poly welding, Electrofusion (EF) welding parameters must be strictly followed to ensure a successful joint.
Control units should operate with barcode marked fittings according to ISO 13950, with a maximum output of 48 Volts. Control units should include safety devices to prevent voltages greater than recommended by the manufacturer. The safety device should operate in less than 0.5 sec. The user should check the suitability of the control unit for use with the fitting supplier.
