Successful application of Botsing Technology welding robot in super high-rise building projects
Date：2021-11-15 Views：612
The workload and difficulty of welding super high-rise steel structures are beyond ordinary people's imagination. The on-site welding of thick plates in high-rise steel frame structures has the following characteristics: (1) the working environment for on-site welding is relatively poor; (2) The welding position on site is limited by the surrounding environment, making welding difficult; (3) The on-site thick plate welding has a large amount of filling. The labor cost, time cost, and management cost of welding are significant, and it is imperative for on-site welding of steel frame structures in super high-rise buildings to shift towards industrialization and automation. BOT is working with RBS to apply welding robots to super high-rise building projects and jointly create automated welding in the field of super high-rise steel structures.
Project Background Introduction
(1) Introduction to Botsing Technology
Botsing Technology is a national high-tech enterprise (BOT) specializing in the research and development, production, and sales of intelligent special robots. The company has an academician expert workstation composed of Academician Pan Jiluan and multiple professors from Tsinghua and Peking University. It has over 100 intellectual property rights and has obtained invention patents from the United States, the European Union, Japan, South Korea, Russia, Singapore, South Africa, and other countries.
The company's products include trackless guide all position crawling welding robots and trackless guide pipe welding robots, which can realize automatic welding of large structural parts or narrow spaces. The products are mainly used in oil and gas chemical industry, shipbuilding, rail transit, energy and power, building steel structures, nuclear power engineering and other fields. Now we are working with RBS to create automatic welding in the field of super high-rise steel structures.
(2) RBS Introduction
The full name of RBS-SPI is Super high rise prefabricated steel structure industrialization system design and construction (SPI), which realizes the true meaning of building industrialization system through the integration of design and construction. The research on SPI system began in 2013. The early experimental research on the outsourced steel plate shear wall, based on the Guangzhou East Tower project, was successful in the laboratory of Tsinghua University, and was highly recognized by experts such as academicians of the CAE Member and national design masters.
(3) Botsing Product Introduction
The trackless all position crawling welding robot is an intelligent special robot system that can autonomously track welds without the need for tracks or guidance. It can meet the needs of large-scale structural components or automated welding in narrow spaces. This robot fills the gap in the international welding field and is an internationally leading and innovative high-end intelligent equipment.
The trackless pipeline welding robot is a special robot developed for fully automatic pipeline welding. The robot achieves functions such as automatic alignment of welds, automatic arc starting and stopping, real-time adjustment of process parameters, and automatic adjustment of welding swing, greatly reducing the dependence on welding personnel's skills.
(4) Application Cases
The Hengqin Headquarters Building project in Zhuhai is inspired by the extraordinary momentum and elegant posture of the Tenglong. The "twin towers and dragons" surround the "dragon beads", with a strong sense of rising lines in the design; The facade design of the tower adopts the concept of "dragon scale", forming
The total land area of the project is 80046.95 square meters, and the total commercial building area is 80000 square meters. The second phase of the project is mainly divided into three individual buildings: a shopping center, a commercial street, and two super high-rise office buildings, which mainly include financial services, business offices, retail supermarkets, banquet catering, entertainment clubs, and other functions.
Assembled steel structure+welding robot technology will become the future development direction
(1) RBS and BOT Super High rise and Space Complex Steel Structure Automatic Welding Application Technology Cooperation Research Center
After a period of investigation and exchange, on October 19, 2020, RBS and BOT established a strategic partnership. Both parties are the only partners in promoting automatic welding technology in the field of housing construction, jointly committed to the promotion of automatic welding technology in the field of housing construction.
(2) Robot welding will become the future welding direction and the difficulties encountered in current engineering practice
At present, in the field of super high-rise buildings in China, due to the large investment scale, high technical requirements, and high collaboration requirements between specialties, the design and construction level are required to be high.
On site welding often becomes a key factor in construction, with high labor and management costs for manual welding. Long and extensive repetitive labor, hot temperatures full of smoke and sparks, high altitude hazardous environments, and difficulty in manual welding process and quality control make enterprise operations high-risk, and the industry faces problems such as a shortage of young people. Promoting technological progress in robot welding is a powerful means to solve industry pain points.
The current bottleneck in the application of automated welding technology in China lies not only in the research and development of equipment intelligence, but also in the construction of systems and application scenarios. The traditional design form of steel structural components, connection design, and construction process arrangement are all key factors that restrict the application of automated welding technology.
Application of Comprehensive Automation Welding Technology on Construction Site in Super High rise Projects
(1) On site 1:1 simulation process test in December 2020
The steel structure design of the Zhuhai Hengqin Headquarters Building project adopts RBS-SPI technology. During the structural design stage, the mutual influence of various links such as production, transportation, and construction was fully discussed among all parties. In order to ensure the smooth implementation of the project in the subsequent construction process, especially to verify the application effect, quality control, and other aspects of the fully automatic welding robot on site, a 1:1 real scale comprehensive experimental study covering deepening, production, lifting, welding, and other aspects was conducted before the commencement of the main steel structure of the project.

Summary
Welding is the most technologically advanced part of the construction process, especially for on-site welding of super high-rise steel structures, which has become a common pain point in the entire construction industry in China.
As an interdisciplinary and comprehensive emerging technology, "prefabricated steel structure+welding robot technology" not only conforms to the direction encouraged by national policies, but also truly solves the structural problems of industry development.
