WELDING ELECTRODE:
The welding rod is composed of two parts: the welding core and the coating. The welding rod is to apply the coating (drug skin) evenly and centripetally on the welding core outside the metal welding core. Different types of welding rods have different welding cores. The welding core is the metal core of the welding rod. In order to ensure the quality and performance of the weld, there are strict regulations on the content of each metal element in the welding core, especially for the content of harmful impurities (such as sulfur, phosphorus, etc.). Limits, superior to base metal.

Zhang Jijun, vice minister of the Ministry of Water Resources, pointed out recently that during the implementation of the national "Tenth Five-Year Plan" and the 2015 Vision Plan, the Chinese government will raise the issue of water conservancy to the top of the national economic infrastructure. This year, the investment in China's water conservancy projects will reach 25 to 30 billion yuan, of which a large portion will be used to purchase advanced water conservancy equipment. These equipment mainly include: advanced water quality monitoring, sewage treatment and water for the protection of water resources. Recycling technology and equipment; construction machinery, dredgers, dredgers, seepage control, hydrology, rain, flood prevention, and communication equipment for water conservancy projects; microelectronics, network technology, information technology for water monitoring and dispatching systems And equipment.
In addition, in the major national project areas such as water supply system, ecological environment construction and hydropower construction, overseas partners will be sought.
