AI Technical Summary

Technical Problem

Existing gantry welding machines have difficulty maintaining stable defocusing and welding quality when welding power steel pipe poles of different diameters and wall thicknesses. In particular, for power steel pipe poles with tapered structures, fixed defocusing is required during welding to ensure welding quality.

Method used

A plasma-focused coil welding structure and a power cord coil welding take-up and take-up structure were designed. The welding radius and defocus of the laser welding gun are adjusted by an electric telescopic rod and a rotating mechanism, and the take-up and take-up of the power cord are adjusted by a cable take-up wheel, so as to achieve stable coil welding operation.

Benefits of technology

Stable welding of power steel pipe poles with different diameters and wall thicknesses has been achieved, ensuring welding quality and efficiency. The reliability of power line deployment and retraction is high, meeting the processing requirements of power steel pipe poles.
