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. |
