What sparks fly when technology meets construction? At the South Erhuan Road West Extension project site in Hefei, Anhui Province, two welding robotic workers have officially "started work," injecting strong new quality productive forces into urban construction with their robust builds and precise "brains," enhancing both quality and efficiency in building projects.

In the project workshop, the welding robots operate tirelessly as "steel craftsmen," running at full capacity and executing precise tasks. These automated devices, specifically designed for welding steel box girder partitions, seamlessly integrate robotic technology with welding processes, making them "super experts" in the construction field. "Traditional manual labor can only complete 80 meters of corner welds in a day, while one welding robot can accomplish 120 meters, increasing production efficiency by about 50%," explained engineer Gan Quan. Even more impressively, one worker can simultaneously operate two or even more welding robots, reducing overall labor costs by 30% to 50%, significantly shortening production cycles and effectively lowering manufacturing costs, achieving true efficient production.

By using pre-programmed precise paths and parameters, the welding robots minimize human interference, ensuring uniform and consistent welds with high precision, eliminating the irregular seams and quality fluctuations common in traditional manual welding. This greatly enhances product quality and consistency. Additionally, the robots, through programming and remote control, allow workers to stay away from hazardous environments, safely completing welding tasks while effectively eliminating health risks from welding gases, thus improving construction safety.

Currently, the project is carrying out the top-pushing operation for the steel box girders. Once the top-pushing process is successfully completed, the bridge bodies on both sides of the road section will achieve precise alignment, steadily progressing toward the goal of completion and opening for traffic.
