As the core load-bearing structural component of the whole machine, the boom of a mini excavator endures complex dynamic loads, impact loads and alternating stress over a long period. It has stringent process standards for welding forming accuracy, weld penetration depth and structural fatigue resistance. Traditional manual welding is plagued by large thermal deformation, inconsistent weld quality and slow production rhythm, making it difficult to meet the demand for large-scale, high-quality mass production.

The DELAMPS Welding Station is equipped with high-performance industrial welding robots and matched special positioners for coordinated and linked operation. It is specially customized with automatic welding process solutions for thick plate splicing and key stress-bearing welds of mini excavator booms. Leveraging the high-precision repetitive positioning capability of robots and equipped with real-time laser weld tracking and adaptive technology, the station automatically corrects workpiece clamping deviations. It realizes full-position automatic flat welding and fillet welding for key welds of the boom throughout the process, perfectly avoiding common quality defects of manual welding such as porosity, slag inclusion, incomplete penetration and welding deformation. The equipment matches the efficient production rhythm of the production line, with alternating loading and unloading at double stations and seamless connection of welding operations. The welding process is stable and controllable with uniform heat input, effectively guaranteeing the overall structural rigidity and welding appearance quality of the boom.

Adopting standardized programmed operation throughout the whole process, the welds are fully and neatly formed with consistent qualified penetration depth. It greatly improves the fatigue resistance and impact resistance of the boom and extends the service life of the whole machine. It not only realizes high-quality, high-efficiency and low-loss mass production for the welding of mini excavator booms, but also thoroughly achieves the goals of standardization, unmanned operation and high-quality production in the welding process.
