20-315mm PP Electrofusion Welding Machine 350A With Electrofusion Welding Unit Scanner And Printer

An electrofusion welding machine is a type of plastic pipe welding machine specifically designed for electrofusion welding. Electrofusion welding is a fusion welding technique used to join plastic pipes and fittings made of materials such as polyethylene (PE) or polypropylene (PP).Electrofusion welding machine Electrofusion machine Electrofusion welder PE electrofusion welding machine PP electrofusion welding machine Electrofusion equipment Electrofusion welding system Electrofusion welding unit Electrofusion control unit Electrofusion welding generator Electrofusion welding device Electrofusion fusion machine Electrofusion fusion equipment Electrofusion fusion system Electrofusion fusion unit Electrofusion fitting welding machine Electrofusion jointing machine Electrofusion fusion control unit Electrofusion welding accessories Electrofusion welding tool

I. Principle of Operation: Electrofusion welding involves the use of specialized fittings that have embedded heating elements. The electrofusion welding machine supplies an electrical current through these heating elements, generating heat that melts the pipe and fitting surfaces. As the melted material cools, it fuses the pipe and fitting together, creating a strong joint.

II. Machine Components: An electrofusion welding machine typically consists of the following components:

   1) Control Unit: The control unit houses the necessary electronics and controls for operating the machine. It allows the operator to set and monitor welding parameters such as welding time, temperature, and voltage.

   2) Electrofusion Unit: The electrofusion unit is responsible for supplying the electrical current to the heating element in the fitting. It delivers the precise amount of current required for the specific fitting and pipe being welded.

   3) Clamping Mechanism: The machine has a clamping mechanism that securely holds the pipe and fitting in place during the welding process. This ensures proper alignment and contact between the surfaces to be fused.

   4) Data Recording: Some electrofusion machines have data recording capabilities, allowing operators to store and retrieve welding parameters and joint information for quality control and traceability purposes.

III. Welding Process: The electrofusion welding process typically involves the following steps:

   1) Preparation: The pipe ends and fitting surfaces are cleaned and prepared to remove any contaminants or dirt.

   2) Marking and Insertion: Electrofusion fittings have marked insertion depths indicating how far the pipe should be inserted. The pipe is inserted into the fitting until it reaches the marked depth.

   3) Clamping: The pipe and fitting assembly is securely clamped using the machine's clamping mechanism. This ensures proper alignment and contact between the pipe and fitting surfaces.

   4) Welding: The electrofusion machine applies an electrical current to the heating element in the fitting, generating heat that melts the pipe and fitting surfaces. The current is applied for a specific welding time determined by the manufacturer's guidelines.

   5) Cooling: After the welding time elapses, the current is turned off, and the molten material solidifies, forming a fused joint. The joint is allowed to cool before releasing the clamping pressure.
