Since the beginning of the twenty-first century, the recovery of the global nuclear energy and its challenges, suggesting the world's nuclear power development is accelerated and turned to the stage of rapid development, China's nuclear power construction by the moderate stage of development. To carry out nuclear power equipment manufacturing high-end development and application of welding materials, nuclear power high-end welding materials domestically, has become the inevitable trend of large-scale nuclear power equipment manufacturing autonomy. Announced by the Chinese long-term nuclear power development plan, 2020, in running nuclear power capacity has reached 40 million kilowatts; September 2010, the State Council issued State Council on the decision to speed up the cultivation and development of strategic emerging industries identified nuclear power as a focus on the development of new energy projects. In the "12th Five-Year" period, the domestic nuclear power equipment manufacturing industry will usher in a huge market space of nearly 500 billion yuan, the amount of nuclear high-end welding materials will greatly increase, which is bound to drive the nuclear high-end application market of welding materials the formation and development.Month 400 tons of the total 2010 production of welding materials, more than the sum of the United States, Japan, Germany, three welding material production, the electrode arc Welding Electrode production accounted for 75% of mechanization and automation Welding Wire accounted for 25% in the manufacturing of key products of the nuclear island, the application of high-end welding consumables is still almost blank. The next few decades, China's nuclear power equipment to produce the required high-end welding consumables will continue to increase market demand for high-end welding consumables will have broad space for development.
