As the tube panels were automatically transported to the welding area, four welding robots simultaneously carried out automatic scanning, positioning, recognition, and welding of the joints on both sides of the tube panels. This marked the first time in China that fully automated welding of such accessories was achieved; the welds turned out to be of high quality, indicating that the project developed by Dongfang Boiler was a complete success and filled a technical gap in the field of automated welding equipment for serpentine tube panel accessories within China’s boiler industry.
The introduction of the welding robot for serpentine tube fittings has successfully overcome the welding challenges and production bottlenecks faced in the workshop, improved welding quality, reduced labor intensity, and ensured the occupational health of employees. This project promotes the deep integration of party building with production and operations, transforming the party’s political advantages into an internal driving force for corporate development; it is a true reflection of Dongfang Boiler’s commitment to implementing the principle of \"using high-quality party building to drive high-quality development\". Adhering to the principle of \"building a company on quality and strengthening it through technology,\" Dongfang Ren has leveraged collaboration to enhance strengths and address weaknesses, successfully bringing projects online ahead of schedule. This has set a new standard for the installation and commissioning of large-scale equipment, resulting in high-quality projects in the field of boiler manufacturing equipment and marking an important step forward in the transition toward intelligent manufacturing.
To address the issues related to the integration of multiple processing steps in the preparation of spiral tubes as well as quality problems in their fabrication, Dongfang Boiler has developed an industry-leading automatic production line for spiral tube preparation. This large-scale flexible production line enables fully automated and intelligent coordination of various processes, including automatic feeding of spiral tubes, flexible transportation, cutting to precise lengths, CNC beveling, tube end polishing, color coding, and automatic stacking. It is capable of handling tubes of various specifications and features self-sensing, self-execution, and adaptive capabilities. Since the launch of the automatic production line for preparing serpentine tubes, the quality of tube processing has improved significantly: production area has been reduced by 66%, efficiency has increased by 270%, and the number of employees required has been reduced by 59%.
