Welding Frame Principal for Digital Stringing Equipment (Tesmec Customized)

As a core structural component of digital stringing equipment, the Welding Frame Principal is custom-designed for Tesmec, a globally acclaimed manufacturer of digital stringing machines. This high-performance welding frame is elaborately engineered to meet the stringent operational requirements of Tesmec digital stringing equipment, serving as the "backbone" that sustains the entire machine’s stability, load-bearing capacity, and operational reliability. With precise manufacturing technologies, high-grade material selection, and professional surface treatment, our Welding Frame Principal fits seamlessly with Tesmec’s digital stringing machines, enabling smooth integration and long-term stable operation in harsh construction environments such as power transmission line erection—winning high recognition from Tesmec.

We strictly comply with Tesmec’s technical specifications to customize the Welding Frame Principal, with clear and standardized product parameters to ensure perfect compatibility with Tesmec digital stringing machines. Known as Welding Frame Principal, this component is available in two customized specifications to meet different operational requirements of Tesmec equipment: the first specification has dimensions of 3700*2000*300 mm and a weight of 735 kg, suitable for large-scale digital stringing machines requiring heavy load capacity; the second specification is 3600*2300*200 mm in size and 510 kg in weight, designed for medium-sized digital stringing equipment that emphasizes flexibility and mobility. Both specifications are custom-fitted to Tesmec’s digital stringing machine models, ensuring accurate installation and consistent performance.

Material selection is the cornerstone of the Welding Frame Principal’s performance, and we exclusively adopt high-quality structural steels—S275JR, S355J2, and E355—that meet EN 10025 European standards, widely recognized in the global heavy manufacturing sector for their excellent mechanical properties and weldability. S275JR offers moderate yield strength (≥275 MPa) and tensile strength (370–530 MPa), making it suitable for general structural load-bearing scenarios; S355J2 is a high-strength grade with a minimum yield strength of 355 MPa and impact resistance tested at -20°C, ideal for dynamic load and critical applications in harsh environments; as a low-carbon quality steel, E355 complements the other two materials with its balanced strength and toughness, ensuring the frame’s durability and structural stability during long-term heavy-load operation. These materials are carefully selected to resist the mechanical stress, vibration, and environmental erosion encountered by Tesmec digital stringing machines during operation.

To further prolong the service life and improve the performance stability of the Welding Frame Principal, we implement two professional surface and heat treatment processes, strictly adhering to international standards to meet Tesmec’s strict quality requirements. The first is Heat Stress Relieving at 400°C, a key process that relieves residual stress generated during the frame’s welding, forming, and machining. By reheating the frame to 400°C and cooling it at a controlled slow rate, we eliminate internal stress, prevent deformation, cracks, and structural fatigue during long-term use, ensuring the frame maintains its dimensional accuracy and structural integrity. The second process is Sandblasting in accordance with ISO 8501-1 Sa 2½ standard, a thorough blast-cleaning process that removes all visible oil, grease, dirt, mill scale, rust, and foreign matter from the frame surface; any remaining contamination traces only appear as slight spots or stripes, creating a clean, rough surface that enhances the adhesion of subsequent coatings (if required) and significantly improves corrosion resistance.

The manufacturing process of the Welding Frame Principal is subject to a strict quality control system, covering three core stages: Material Input, Welding, and Machining, to ensure every product meets Tesmec’s standards. In the Material Input stage, we conduct strict incoming inspections on S275JR, S355J2, and E355 materials, verifying their chemical composition and mechanical properties to ensure compliance with EN 10025 standards and Tesmec’s technical requirements. The Welding stage adopts advanced automatic welding technology, with professional welders operating in strict accordance with welding procedures to ensure uniform weld seams, high strength, and no defects such as porosity or cracks—critical for maintaining the frame’s load-bearing capacity. The Machining stage uses high-precision CNC machining equipment to process the frame’s installation holes, connection surfaces, and key dimensions, ensuring the size error is within ±0.5 mm, which guarantees seamless assembly with other components of Tesmec digital stringing machines and avoids installation problems caused by dimensional deviations.

The Welding Frame Principal is specifically applied to Tesmec digital stringing machines, which are widely used in power transmission line construction, cable erection, and other infrastructure projects. Tesmec’s digital stringing machines are known for their high performance, reliability, and advanced technology, featuring a unified frame design, optimized wiring systems, and modular software platforms to ensure high efficiency and stability. As a core component of these machines, our Welding Frame Principal bears the weight of key parts such as the traction system, control system, and conductor clamp, and resists the vibration and impact generated during stringing operations. It plays a vital role in ensuring the smooth operation of Tesmec digital stringing machines, improving construction efficiency, and reducing equipment failure rates.
