Red May for chemical industry workers! Reply reward! ---------------------------------------------- The past decade has been a period of rapid development in China’s chemical industry, marked by the emergence of many new processes, products, and equipment. There has also been significant progress in China’s chemical processing equipment, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and greater use of domestic equipment. We invite everyone to share their insights and discuss these topics together; let’s cheer for Made in China and support the development of chemical processing equipment! ========================== On September 3, 2021, reporters from Chuan Guan News learned from Dongfang Electric Group’s Dongfang Boiler Co., Ltd. that the industry’s first fully automated laser sealing weld for large-scale high-pressure containers was successfully developed by this company, filling a gap in China’s domestic industry!
The robotic arm moves with precision, and the welding sparks shine brightly. Fully automatic laser sealing welding equipment represents the integrated application of robotics, mechanical vision, and laser welding technology; it eliminates the reliance on welders’ technical skills. It addresses the issues associated with traditional sealing welding using TIG welding, such as slow welding speeds and the need to regularly replace tungsten electrodes and welding wires. This equipment enables automatic correction, positioning, and alignment of all sealing welds on heat exchangers, as well as automatic gas supply and welding processes. It significantly enhances the automation and intelligence level of workshop equipment, greatly reducing the welding time for each seam. This not only improves welding efficiency and reduces labor costs but also saves money associated with groove preparation, tungsten electrode wear, and welding material consumption.
