Including hydraulic support top beam, cover beam and base (referred to as the three large parts) and bridge, balance ear plate and other components of the automatic robot welding station, mainly for small batch, multi-batch customized products, welding is complex, large amount of welding, need to be divided into multiple welding. The project adopts multi-robot double displacement, multi-welding process, multi-layer multi-channel and off-line programming technologies to interact and dock with intelligent crane, dust removal system, dust removal room and AGV information to promote high-quality and efficient welding, welding reactable rate >85%, and all welds meet the grade weld standard.
