Welding and cutting equipment Application of shipbuilding industry - china Multiservice Multiplexer

Ship-welding technology is the key to our modern shipbuilding mode, one of the technologies, increase productivity, reduce shipbuilding cycle, lower manufacturing costs, improve manufacturing quality is the eternal theme of the entire shipbuilding industry. Welding technology in the whole shipbuilding process accounted for a decisive position, ship welder during manufacture of the hull about 40% of the total working hours, while the welded hull manufacturing costs account for about 30-50% of the total cost can be seen welding and cutting equipment in the shipbuilding industry in the degree of importance.
    
    Hong-US Economic Information Consulting Co., Ltd. in 2009 in the second half of the welding and cutting equipment, market research, the shipbuilding industry as a welding and cutting equipment, key application sectors, enterprises of the shipbuilding industry customers a sample study of 17 companies, ranging from ocean-going ships Production-based large-scale shipbuilding enterprises, such as the Dalian Shipbuilding Industry Co., another ship within the inland-based companies, such as the new joint Wuhu shipyard.
    17 shipbuilding enterprises in the holdings of the statistics, an average of welding and cutting equipment to maintain shipbuilding enterprises reached 1468 units, which inverter welding and cutting equipment to maintain capacity of 441 units, the traditional welding and cutting equipment to maintain capacity of 1027 units. Reached a maximum tenure of about 3,000 units for the Hudong-Zhonghua Shipbuilding (Group) Company Limited. Compared to the shipbuilding industry and other industries, such as steel, general machinery, rail vehicles, construction, etc. capacity to maintain the highest level is the various industries the demand for welding the number of the most concentrated industries.
    The number of procurement observation, in 2009, 94% of the shipping companies purchase welding and cutting equipment, with an average purchase price of 15,543 yuan / station. These enterprises an average of 135 units purchased welding and cutting equipment, inverter welding and cutting equipment, 71 sets of traditional welding and cutting equipment, 64 sets. The proportion of the new procurement inverter in the inverter is much higher than the proportion of ownership in these two notable differences between the proportion of the response of the inverter welding and cutting equipment in the shipbuilding industry in the broad application prospects to replace the part of the inverter models the traditional model is the future trend of development.
   Companies interviewed, 65% of the enterprises that the inverter will further replace traditional welding and cutting equipment, welding and cutting equipment, and most of the enterprises that the inverter welding and cutting equipment, accounted for more than traditional equipment. After calculation, inverter welding and cutting equipment, welding and cutting equipment accounted for the proportion of 9-10 years in time to 86%. To lead this trend is largely due to inverter welding and cutting equipment, small size, easy to carry; energy-saving and efficient features in line with national policy. Vast majority of users interviewed enterprises recognized Inverter Welding equipment and technology to meet the customer needs and trends that the inverter welding and cutting equipment, energy saving, energy saving, easy to field work.
    Automation, mechanization level, the higher the shipbuilding industry, CO2 Gas Shielded Welding technology has become a mature technology shipbuilding industry. As China's shipbuilding industry, the level of the continuous improvement of manufacturing, welding equipment industry meet the use requirements will be further improved, the proportion of inverter welding and cutting equipment will be gradually increased, reaching the dominant position; the mix of a variety of welding technology will be towards a more energy-efficient, clean, efficient direction, the proportion of gas-welding will be further expanded.
    Welding and cutting equipment, the definition of this project: This article referred to in arc welding and cutting equipment is provided by the heat energy from the welding, cutting equipment. Does not include other welding and cutting equipment, such as resistance welding, brazing, flame cutting and so on. Equipment categories include: Shielded Metal Arc Welding equipment (manual welding), gas shielded arc welding equipment, welding equipment, plasma cutting equipment, and others (including the submerged arc welding, stud welding, etc.).
    Investigation lasted more than two months, the total number of over 350 research companies, including welding equipment manufacturers is about 80, almost include all the major domestic manufacturers; industrial users 200 or so, involving 13 industries; dealer is about 70; Industry Association ; upstream suppliers dozen. Covers all production and application of welding and cutting equipment active in the region.
