Does the thermal deformation of the cast iron base cause welding deviation? Unveiling the Thermal Compensation Scheme of ZHHIMG Granite Base Solar Welding Platform.

In the production of solar panels, the welding accuracy directly affects the product quality. The traditional cast iron base, due to its high coefficient of thermal expansion (approximately 12×10⁻⁶/℃), is prone to deformation under high welding temperatures and fluctuations in environmental temperatures. When the 1-meter-long cast iron base is heated by 10℃, it may elongate by 120μm, causing the welding position to shift, affecting the performance and lifespan of the solar panel, and also increasing maintenance costs due to stress concentration.

The ZHHIMG granite base stands out with its natural advantages. Its coefficient of thermal expansion is only (4-8) ×10⁻⁶/℃, less than half that of cast iron, and it has strong dimensional stability when the temperature changes. The hardness reaches 6-7 on the Mohs scale, capable of withstanding the heavy pressure and impact force of welding equipment. The excellent damping performance can also absorb vibration, creating a stable environment for high-precision welding.

On this basis, ZHHIMG's thermal compensation algorithm further improves the welding accuracy:

Real-time monitoring: High-precision temperature sensors are distributed at key parts of the base to collect temperature data in real time (with an accuracy of 0.1℃), and the temperature field of the base is comprehensively analyzed through multi-point data.
Precise modeling: Based on a large amount of experimental data, combined with factors such as the thermal expansion coefficient of granite and the shape and size of the base, a thermal deformation model is established to predict the deformation in all directions at different temperatures.
Dynamic compensation: The system adjusts the movement trajectory of the welding equipment in real time based on the calculated deformation. If deformation ΔX in the X direction is detected, the mechanical arm moves in the opposite direction by ΔX to counteract the influence of thermal deformation.
Intelligent optimization: The algorithm can automatically optimize the model and compensation parameters based on the welding process, ambient temperature, and the service life of the base, continuously maintaining high precision.

In practical applications, after a certain enterprise introduced the ZHHIMG granite platform, the defect rate of its products dropped from 10% to within 3%, and the production efficiency increased by 30%.
