Principle of Operation

Socket fusion is a jointing process in which two compo-
nents are joined to each other by welding both, in two
separate welding operations, into a fitting of slightly
larger diameter than the components. The joint is
achieved through the plasticization of the component
butt and the inside surface of the fitting, the insertion
of the component into the fitting, and allowing them
to cool down as one new piece. The process includes the
following operating steps:
• The socket welding machine is placed on a stable and
level surface.
• The clamps that match the size of the components to
be jointed are installed on the machine carriages.
• The spigot and the socket that match the size of the
components to be jointed are installed on the heating
element.
• The heating element is connected to the power supply
and set to the temperature applicable to the intended
welding operation. Then the user has to wait for this
nominal temperature to be effectively reached. Mea-
sure the actual temperature at four different points on
the heating spigot; the average of the temperatures
has to be in line with the nominal temperature.
• The component is properly cut, possibly chamfered
depending on the welding standard, deburred and
cleaned, then pre-clamped, just as the fitting, both
aligned to each other with the carriage in the start-up
position, and finally clamped securely.
• The component is slid into the socket, the fitting, over
the spigot, and both are heated to plasticization.
