IIHydraulic welding rodUniversal Testing MachineDetailed introduction of equipment

The equipment adopts a dual column structure with oil cylinders placed underneath, and a high-strength screw and cast steel body form a stable frame, effectively reducing operational vibration. The hydraulic system is equipped with an imported low-noise gear pump, with a working pressure of 25MPa, and is matched with a servo valve to achieve stepless speed regulation loading of 0.2-50mm/min, accurately matching the testing requirements of different welding rods. The measurement and control core adopts high-precision force sensors and photoelectric encoders to collect real-time test data and convert it into load displacement and stress-strain curves. The software automatically calculates key indicators such as tensile strength and yield strength.

The operating end is equipped with Windows system specific software, which supports editing multiple standard test processes such as ASTM and AWS. The test results can be exported to Excel reports and printed, meeting CNAS certification and data traceability requirements. In terms of safety design, it is equipped with triple protection of overload stop, mechanical limit, and emergency stop button to avoid the risk of sample fracture and splashing.

3、 Core advantages

1. Precision for welding rods: Optimizing the clamping system based on the characteristics of welding rod joints, combining V-shaped jaws with wear-resistant lining plates to prevent slipping and eccentricity, and capturing key data such as yield points with level 1 precision sensors to solve testing errors caused by virtual welding and slag inclusion.

2. Full scene adaptability: The standard configuration covers mainstream welding rod specifications, and accessories such as high-temperature furnaces and bending aids can be selected. It supports environmental testing from -70 ℃ to 350 ℃ and simulates the welding rod performance under special working conditions such as ships and buildings.

3. Intelligent and efficient operation and maintenance: The software comes with a fault self diagnosis function, and testers and administrators have hierarchical permission management to ensure data security; Lifetime warranty for core components, 24-hour technical response, reducing maintenance costs in the later stage.

4. Strong compliance with standards: Built in algorithms for welding rod specific standards such as GB/T 983, automatically determine whether the test results are qualified, support international standard data output, and assist in export welding rod certification.
