At present, the competitive landscape of China's machine tool industry has entered the stage of killing of high-end brands. The brand at this stage has been refined into the medium, middle, upper and middle and higher market segments. In the mid-market, prices are mainly dependent on price wars. Difficulty has led many brands to start upstream and strive to obtain more brand value and development space. Under this circumstance, the Chinese machine tool industry faces many challenges, especially for Chinese local companies, which concentrate on low-end products. With price as the main means of competition, the ability to resist risks is not strong, and the degree of industrial concentration is low. Even in this environment, there are still some new brands entering the market, showing the intense competition in the industry. The fierce competition in the industry also promotes the high-end development of China's machine tool industry, because only high-quality brands will gain a larger market share in order to compete with foreign companies. In the new round of five-year planning, according to the 12th five-year development plan for the CNC machine tools industry promulgated by the state, with the theme of scientific development, to accelerate the transformation of the development approach as the main line, and to take the structural strategic adjustment as the main attack direction, take the two integrations. New industrialization road. Grasping the important strategic opportunities in the development of the industry, and taking the development of CNC plasma cutting machines as the leading tool, the host as the leader, and the improvement of supporting systems as the foundation, we will focus on breaking through the weak links of CNC systems and functional components and accelerate the industrialization of high-end CNC machine tools. The supporting functional components needed for medium-to-high-end CNC machine tools were mentioned in the 12th Five-Year Plan. The development of these functional components has become a bottleneck restricting the development of the machine tool industry.
The Twelfth Five-Year Plan also explicitly proposed to eliminate backward production capacity, such as production of high-pollution, high-energy-consuming products, production and development of high-tech products, upgrading of China's machine tool products, using high technology to go abroad and go global. During the 12th Five-Year Plan period, with the upgrading of industries in the downstream user industry, higher-level technical requirements will surely be raised for the machine tool industry, as well as providing greater market demand.
1.Welding materials
In Welding, substances called filler materials or consumables are used. As the name implies, these substances provide filler or a body of molten materials that provides a strong bond to be formed between the base metals used. Most welding processes will also require some form of shielding to protect both the main components and filler from being oxidized during the process.
The type of welding materials used during welding depends on the nature of the job intended. Electrodes draw the necessary energy in order to perform welding applications. Luoyang Golden Egret Company has any kind of welding materials include CTC Welding Rod /rope, SCTC welding rod/rope, TC electronic welding rod, Ni-based welding rod, flux-cored Welding Wires, solid welding wires and etc.
Welding can be applied in different kinds of industries such as building and construction, oil and gas, marine, power generation, steel, mine tools, automobile, transportation and etc.
