Electrofusion Welding Machines

An Overview of Electrofusion Welding

Electrofusion welding has been a reliable method for joining polyethylene pipes and fittings used in gas, water, sewage, and industrial applications for decades. Proper, secure, and durable welding connections require high-quality pipes and fittings, experienced and certified welders, and superior welding equipment.

AGRU Electrofusion Technologies are well-suited to support electrofusion across a wide array of projects thanks to its fittings design and capabilities, weld safety with short-circuit protection, and extensive documentation and data management system.

AGRU Electrofusion Technologies

AGRU’s electrofusion technology is distinguished by advanced engineering and unique features that ensure durability and reliability. These precision-engineered electrofusion couplers utilize state-of-the-art manufacturing techniques and the highest quality raw materials, tested for exceptional resistance to slow crack growth, corrosion, and UV radiation. AGRU electrofusion design ensures long-term integrity and is supported by an embedded welding wire that prevents corrosion and simplifies maintenance.

To maintain flawless performance, AGRU implements stringent quality control measures. These include post-production resistance testing of every fitting and regular X-ray inspections. These measures are crucial for ensuring reliability in large-scale applications. AGRU further enhances its electrofusion systems with innovative features such as data logging capabilities, user friendly interfaces, and advanced visualization tools. These advancements improve connectivity, elevate monitoring, and ensure compliance with rigorous quality standards.

Weld Safety

Several Factors can influence electrofusion welding if installation and welding guidelines are not followed. These factors can lead to short circuits and potential ignition of the material. For example:

AGRU’s electrofusion welding machines with Short Circuit Protection (SCP) support improved weld safety*. This technology allows the machine to detect short circuits and stops the welding process immediately. The system detects short circuits based on variations in the heating wire resistance of the fittings. The system documents and analyzes these resistance changes, which
stops the welding process under flagged conditions.

The SCP system is compatible with all AGRU injection-molded fittings  ranging from OD 20mm to OD 500mm and is implemented in all new AGRU electrofusion welding machines.

Documentation and Data Management System

All new AGRU electrofusion welding machines feature a robust documentation and data management system. The entire weld history can seamlessly integrate into the AGRU WeldNet data management system. This comprehensive system documents, evaluates, and identifies all welds, including those affected by short circuits. The AGRU WeldNet system is at the heart of your entire welding operation. Welding reports can be easily retrieved from the machine via a USB stick, analyzed using the AGRU WeldNet system, and printed directly from the machine.
