The park started construction. According to reports, the park currently has 16 projects and plans to invest a total of nearly 3 billion yuan, covering the three major functional platforms of "standard testing and assessment, training and training of talented people, transfer of achievements," and robot system integration and ontology manufacturing. The annual output value is nearly 4.5 billion yuan. It is expected that by the end of this year, the industrial park will gather more than 30 companies, forming a production capacity of 40,000 sets of industrial robots and key components, and an annual production value of 20 billion yuan. The development of the robot industry in the Liangjiang Industrial Park has a clear positioning. Li Guang said: “Two rivers are not manufactured for development and manufacturing, but are for the sake of development and construction of ecological industrial chains.†“We also have a clear roadmap for the technology.†Li Guang said that the robotics technology in the industrial park will drive ontology with system integration, and then use the ontology to drive the development of key components. For example, the development of basic components such as speed reducers needs a lot of Technology accumulation. The company will focus on industrial robots first and then gradually develop service robots. The ultimate goal is to develop service robots oriented to the general public. He said that compared with Shanghai, Shenzhen and other places, the Chongqing robot industry started relatively late, but the automobile, motorcycle and electronics industries in the Chongqing area are all very developed, and the market potential of the robots needed is huge. We are confident that by the year 2020 we will achieve an annual output of 10,000 industrial robots, more than 50,000 service robots and special robots, and an annual output value of 30 billion yuan for the robotics and smart manufacturing industries. We will build a world-class, leading Chinese intelligent manufacturing highland. Their confidence comes from multiple advantages such as market and geography. It is understood that Chongqing is one of China's three old industrial bases and one of the top ten equipment industry bases. It is also an important automobile, shipbuilding, and military base in China and has many skilled workers. In addition, there are many well-known companies here, including Chongqing Changzheng Heavy Industry Co., Ltd., Qingling Automobile (Group) Co., Ltd., and Southwest Aluminum Group Co., Ltd. Build multiple innovation platforms In order to attract more robot manufacturers to settle down, the park has developed a series of measures to encourage the development of robots. According to Li Guang, the water and soil high-tech park will be built into a complete robot assembly and assembly area for key components, as well as a fruition incubation and transfer platform, a public R&D testing platform, a talent education and training platform, a financial leasing support platform, and an exhibition operation and maintenance platform. District 5 platform "as one of the robot industry park. First, the park will establish a national robot detection and assessment platform.

It covers an area of ​​approximately 16 acres and plans to invest 200 million yuan. The project plans to build two platforms for robot research and development and testing. Among them, the R&D platform is mainly engaged in the tracking of robotic international standards, the revision of national standards, the research and formulation of robotic detection technologies and methods, and the research and revision of robotic products and access systems for key components. The detection platform will be dedicated to the detection and calibration of robotic products and components. It will focus on building seven major testing centers including complete machines and safety, special testing, environmental and explosion proofing, metrology calibration, and robot parts, unmanned systems, and industrial 4.0. According to the relevant plans, we will strive to build the Chongqing Branch Center into a united robot component inspection, ontology, complete machine, environmental testing, system assessment, standard formulation, system solutions, and personnel training training through a three-year project. National third-party robot testing and evaluation platform. Second, the Liangjiang Robot Industry Park will establish a talent training platform. It is understood that the first robot professional education and training institution is currently under construction and the annual training will reach 5,000 people. Recently Chongqing Chongqing Mechanical and Electrical Vocational Technical College, Chongqing Guoyang Holdings Co., Ltd. and Chongqing Institute of Green Intelligent Technology, Chinese Academy of Sciences invested in the construction of "Chongqing Liangjiang Robot Training and Application Center (College)" in the park groundbreaking. The project covers an area of ​​85.7 mu and invests 560 million yuan. It is currently the largest and most professional industrial robot training and education institution in Chongqing. It is understood that the school's teaching model is divided into three categories, namely, academic education, engineer promotion and social strength training. “We are trying to open up the production, learning and research chain of local vocational colleges and research institutes and industrial parks to create a first-class talents incubation base for the development of the Chongqing robot industry.†Deng Anxuan, general manager of Chongqing Zhongke Guoyang Holdings Co., Ltd., said that by then, the college will It has formed a talent supply capacity of 3,000 students and more than 5,000 trainees per year. Second, the park will establish a financial services system. Li Guang told reporters, "A lot of research on users and manufacturing companies has found that many small and medium-sized enterprises are facing financial difficulties. In response to this problem, we have established a finance leasing company. We have built financial platforms for manufacturing and customer end manufacturers. According to reports, the related work of Chongqing Liangjiang Robotic Finance Leasing Co., Ltd. has been started, and the company's president, Huang Jianhua, said that this company is the first domestic company to rent robots. Create a domestic robot brand "Through multiple efforts, our ultimate goal is to create a domestic robot brand." Li Guang said that the industrial park has adopted the "introduction, digestion, absorption, and innovation" path, relying on the intellectual support, platform support, and industrial base of the Chongqing Research Institute of the Chinese Academy of Sciences. Support, build national standards, calibration, testing, engineering and technology research centers and incubation platforms, integrate globally advantageous resources, and introduce well-known enterprises at home and abroad. It is reported that the park will also promote the development of cutting-edge technologies through the introduction of world-renowned enterprises. Recently, the Kawasaki Robot System Integration and Robot Manufacturing Base project led by Kawasaki Heavy Industries of Japan started construction at the Water & Soil Hi-tech Park in the Liangjiang New District.

According to reports, the center will focus on industrial robots such as welding, painting, transportation, and assembly in the field of smart manufacturing equipment, as well as specialized robots for security, construction, rescue, and medical treatment, and introduce, incubate and cultivate a batch of high-tech robot companies. If welding with a solid wire is satisfactory, why use a higher priced flux-cored wire? A flux-cored wire is optimized to obtain performance not possible with a solid wire. For many welding applications like vertical-up welding, flat welding, welding over galvanized, or welding hard-to-weld steels, a flux-cored wire can do it better and faster.

Although gas metal arc welding (GMAW) with a solid mild steel wire is popular, easy-to-use, and effective for many applications, it does have limitations and drawbacks. For example, GMAW is slow for out-of-position welding. It is either limited to short-circuit transfer, which is restricted by many welding codes due to the tendency for lack-of-fusion, or pulse transfer, requiring a special welding power source. It also requires very clean steel.
The ability to add a variety of materials to the core of the welding wire allows many performance enhancements to be made. Slag formers are added to shield the weld pool and shape and support the weld. Iron powder is used to increase deposition rates. Powdered alloys are added to produce low-alloy deposits or improving the mechanical properties. Scavengers and fluxing agents are used to refine the weld metal.
FCAW: Wire Selection Based on Application
Flux-cored arc welding gas-shielded (FCAW-G) wires were introduced to the market around 1957. The flux-cored arc welding self-shielded (FCAW-S) wires were introduced to the market later, around 1961.
The core ingredients for FCAW-G wires have been formulated to obtain performance impossible to achieve with a solid GMAW wire. As all of shielding is provided by the shielding gas, the core materials may be carefully selected to maximize a certain area of welding performance, such as obtaining smooth spray-type transfer with 100% carbon dioxide shielding gas and welding speeds twice as fast in the vertical position.
The FCAW-S wires on the other hand, the core materials must provide all of the shielding. The core materials generate its own shielding gases, slag formers, and compounds to refine the weld pool. The benefits of self-shielded flux-cored wires lie in its simplicity. They may be used outdoors in heavy winds without tenting and the additional equipment required for gas shielding.
There are several popular types of flux-cored wires and how they can increase welding productivity:
For semi-automatic out-of-position welding, E71T-1 wires offer unsurpassed performance. Its fast freezing rutile slag provides the highest deposition rates in the vertical-up position, up to 7 pounds per hour, unmatched by any other semi-automatic arc welding process. In addition, the E71T-1 wires also offer an exceptionally smooth welding arc and minimal spatter, even with 100% carbon dioxide shielding gas. Argon/carbon dioxide blends are used for the smoothest arc and best out-of-position performance. These are reasons why E71T-1 is the world's most popular flux-cored wire. It is a top choice for shipbuilding, structural steel, and general steel fabrication applications.
For semi-automatic out-of-position welding without shielding gas, E71T-8 wires offer the highest deposition rates. Lincoln Electric's NR®-232 can deposit 4.5 lbs./hr. in the vertical-up position, 50% faster than other E71T-8 wires. Since this wire is self-shielded, it is widely used outdoors and in field erection of structural steel.
For semi-automatic welding in the flat position, the fastest way to join thick steel plate is with an E70T-4. It offers the highest semi-automatic deposition rates, up to 40 pounds per hour. This wire is widely used to join thick steels where there is no Charpy impact toughness requirement. This wire is also self-shielded, allowing it to be easily used outdoors.
The highest deposition rate gas-shielded flux-cored wire is E70T-1. Compared to E70T-4, they offer slightly lower deposition rates of up to 30 pounds per hour, but they offer a smoother welding arc and Charpy impact toughness properties. It offers higher deposition rates than GMAW, handles dirtier plates, and uses lower cost 100% carbon dioxide shielding gas. E70T-1s are widely used in structural steel fabrication shops.
For welding coated and galvanized sheet steels, E71T-14 is the wire of choice. The self-shielded E71T-14 wire has core materials which explode in the arc, volatizing the steel coating, minimizing cracking and porosity. The result is higher quality welds and fast welding speeds. E71T-14 wires are widely used in the automotive industry for fabricating galvanized steels.
What is the fastest way to weld hard-to-weld steels? E70T-5 gas shielded wire offer excellent crack resistance on hard-to-weld steels, such as T-1 quench and tempered steels, abrasion resistant steels, and free machining steels. E70T-5 has a basic slag system, similar to 7018 stick electrode, which removes phosphorus and sulfur from the weld metal, which can cause cracking, porosity, and poor toughness. E70T-5s have lowest diffusible hydrogen levels among the flux-cored wires, resulting in excellent resistance to delayed hydrogen cracking, as. In addition, they offer exceptional Charpy impact toughness properties.
