      Ship Welding technology is the key of modern shipbuilding mode one of the technologies, increase productivity, reduce shipbuilding cycle, reduce manufacturing costs, improve manufacturing quality is the eternal theme of the entire shipbuilding industry. Arc welding process in the entire shipbuilding process plays a decisive role in accounting for the ship hull manufacturing welders about when 40% of the total working hours, while the hull welding cost about 30-50% of the total cost of manufacturing can be seen welding and cutting equipment in ship industry importance.
2009 in the second half of the welding and cutting equipment, market research, the shipbuilding industry as a key application of welding and cutting equipment industry, ship industry, enterprises and a sample of users in 17 companies, ranging from ocean-going ship production enterprise mainly large vessels such as the Dalian Shipbuilding Industry Co., another ship within the inland-based companies, such as the new joint Wuhu shipyard. 17 ships in the enterprise to keep the amount of statistics, the average welding and cutting equipment to maintain the ship companies reached 1468 units, which inverter welding and cutting equipment to maintain capacity of 441 units, traditional welding and cutting equipment to maintain capacity of 1027 units. 3000 reached the highest reserves of aboutTo Hudong-Zhonghua Shipbuilding (Group) Co., Ltd.. Compared to the shipbuilding industry and other industries, such as steel, general machinery, rail vehicles, construction, etc., to maintain the highest volume levels, is the demand of various industries on the number of welding most concentrated.
      Number of observations on the purchase, in 2009, 94% of the shipping companies purchase welding equipment, the average purchase price of 15,543 yuan / station. The company purchased an average of 135 units welding equipment, inverter welding and cutting equipment 71 sets, 64 sets of traditional welding and cutting equipment. The proportion of the new procurement inverter in the inverter is much higher than the proportion of holdings, a significant proportion of these two differences, the reaction of the inverter welding and cutting equipment in ship industry, potential applications, to replace part of the inverter models traditional model is the future trend. Enterprises were visited, 65% of enterprises believe that the inverter welding and cutting equipment will further replace traditional welding and cutting equipment,And the vast majority of enterprises believe that the proportion of inverter welding and cutting equipment than traditional equipment. After calculation, Inverter Welding Equipment Welding Equipment account the proportion will be increased to 9-10 years in 86%. Leading this trend is largely due to inverter welding and cutting equipment, small size, ease of handling; energy efficient features in line with national policy. Most users interviewed inverter welding equipment approved enterprise technology to meet user needs and trends, that the inverter welding and cutting equipment, energy saving, energy saving, easy to field work. Automation, mechanization level, the higher shipbuilding industry, CO2 gas shielded welding technology has become mature workers shipbuilding industry Arts and Technology. With the development of China's shipbuilding industry, the manufacturing level to continuously improve, welding equipment industry adapt to the use request will be further increased, the proportion of inverter welding and cutting equipment will be gradually increased, Dadaozhuti status; Gezhonghanjie Gongyi proportions Ye Qiang towards more energy efficient, clean, efficient direction, the proportion of gas-welding will be further expanded. The project definition of welding and cutting equipment: Welding equipment mentioned in this article is to provide heat energy from the electric arc welding and cutting equipment. Does not include other welding and cutting equipment, such as resistance welding, brazing, flame cutting and so on. Equipment categories include: electric welding rod Arc welding equipment (manual welding), gas welding equipment, welding equipment, plasma cutting equipment, and others (including welding, stud welding, etc.). Investigation lasted more than two months, the total number of over 350 research companies, including welding equipment manufacturers about 80, including almost all the major domestic manufacturers; industry users about 200, involving 13 industries; dealer about 70; Industry Association ; upstream supplier dozen. Covers all production and application of welding and cutting equipment, active regions.
