Steel structure welding robots: the innovative force of the construction industry

In the process of the construction industry's transformation towards intelligence and greenness, steel structure welding robots are driving industry change with disruptive technologies. As the core carrier of modern intelligent manufacturing, this type of robot has not only reconstructed the traditional welding process standards through the triple breakthroughs of automation, precision and safety, but also become the key guarantee for the high-quality delivery of large-scale projects.

The steel structure welding robot realizes the automation of the entire welding process by integrating high-precision servo systems and intelligent control algorithms. Its 3D visual sensor can scan the contour of the component in real time and automatically generate the optimal welding path, compressing the hours required for traditional manual programming to minutes. In the steel structure construction of the Hangzhou Asian Games venues, the average daily welding volume of a single robot reached 180 meters, which is 5 times more efficient than manual welding and shortens the construction period by 40%. Multi-axis linkage technology gives it super flexibility, which can complete complex spatial trajectories such as overhead welding and vertical welding, and overcome the welding difficulties of special-shaped components.

With arc tracking and molten pool monitoring technology, the robot welding process can achieve micron-level precision control. By dynamically adjusting the current, voltage and wire feeding speed, the penetration consistency of multi-layer welding of 10-50mm thick plates is ensured, and the defect rate of pores, slag inclusions, etc. is reduced to below 0.3%. In the steel grid project of the terminal building of Beijing Daxing Airport, the welding robot made the ultrasonic inspection of 28,000 welds reach a one-time pass rate of 99.6%, and the structural stability far exceeded the manual welding standard. The intelligent process database has accumulated millions of parameter solutions to achieve precise adaptation from Q345B high-strength steel to S690QL special steel.

The Xizhang steel structure welding robot reduces welding fume emissions by 80% through pulse waveform control and gas precise ratio technology, and cooperates with an integrated dust removal system. While ensuring welding strength, it significantly suppresses the deformation of thick plates and can reduce steel loss by about 12% each year.

In the future, with the breakthrough of modular expansion and cluster control technology, steel structure welding robots will become the core productivity of the new construction industrial system, opening a new era of "robots making robots".
