High-end Equipment Manufacturning

Shield tunneling machines are designed and manufactured one-on-one based on specific geological conditions of the project, and cannot be standardized for mass production

The harsh service environment requires high reliability, and the process almost covers all typical discrete manufacturing processes, with high assembly accuracy requirements

The automation and digitalization foundation of key production equipment is weak; The degree of data collection and system integration is low, and there are information silos; Lack of transparency and collaboration in production management processes

The internal structure is complex, the workspace is limited, and the accessibility of the welding gun is poor. The thickness of structural steel plates far exceeds that of conventional steel structures; There are various forms of welding seams for structural components. The quality of shield tunneling machine welds is directly related to the safety of major engineering projects, and the inspection standards are strict

The welding robots in use are mostly used for small component welding, and the intelligent welding equipment for whole piece welding has low usage and low welding efficiency
