Welding and cutting, is one of the key production technology shipbuilding industry, related to welding, cutting and quality testing equipment is the main process equipment shipbuilding enterprises. During 2008 China Shipbuilding Industry Development International Forum, advanced shipbuilding welding and cutting and quality inspection technology forums thus been focused on the shipbuilding sector professionals. Welding: focus on more efficient and director of the Professional Committee of China Association of welding shipbuilding Chen this made a "Chinese ship welding technology progress" at the forum report. According to him, CO2 gas shielded semi-automatic welding technology is the application rate in China's shipbuilding enterprises reached 60% to 65%, more than 40 kinds of shipbuilding welding processes applied to the construction of various types of ships; shipbuilding industry welder welding material per day consumption of 15 kg, side welding pad use amounted to 700,000 meters, more energy-efficient welding equipment application rate of 95%. Advanced and efficient welding technology for China to improve shipbuilding efficiency, reduce shipbuilding costs, improve quality and has played an important role in shipbuilding. The Chen pointed out that in the field of ship welding equipment and materials, a large number of advanced welding materials and equipment to achieve a localization, AC-DC rectifier arc welding machine and inverter type welding machine applications continue to be developed. Meanwhile, to meet the requirements of energy saving and environmental protection, the backbone of China's major shipping enterprises have been eliminated energy consumption, serious pollution of acetylene gas, and liquefied petroleum gas instead of propane and natural gas, low toxicity, low dust electrode further promote energy-saving inverter welding power source being replaced by high-energy rotary arc welding power source. Although laser welding technology currently used in China's shipbuilding industry in not blank, but China and Germany to develop high-power laser ship building technology projects have been started in 2005. Chen said Ben, to meet the needs of shipbuilding and efficient, "Eleventh Five-Year" of welding mechanization and automation rate to reach 70%, welding quality passing rate increased by more than five percent more than the original, welding 5% lower than the original cost, welders welding material per day consumption increased by 20% than the original. He believes that to achieve these goals, the regional shipping enterprises should adhere to the modular construction, adhere to the direction of welding fine management, adhere to the standardization of the direction of welding, stick welding research leading direction. Cutting: the pursuit of automation engineer Shanghai Shipbuilding Technology Research Institute Yan Hao Peng made in its "hot modern shipbuilding cutting automation solutions," the report pointed out that in recent years to adapt to the needs of modern shipbuilding, a number of advanced automated thermal cutting technologies such as CNC flame cutting, CNC plasma cutting, CNC pipe intersecting line cutting, robotics and other automatic cutting profile has been introduced in the shipbuilding industry, breaking the previous cycle of troubled ship construction material cutting bottleneck fundamentally as to promote the rapid growth of the total shipbuilding aid thruster. For automated thermal cutting technology application status of China's shipbuilding industry, Yan Hao Peng said in terms sheet metal cutting, CNC plasma cutting has dominated, CNC laser cutting machine has also appeared; in terms of pipe cutting, medium-sized shipping enterprises have adopted automation cutting equipment; in terms of profile cutting, only some backbone enterprises ship equipped with automated cutting equipment, and most shipping enterprises are still using manual methods of cutting. After the introduction of the world's shipbuilding industry advanced automated cutting technology development situation, Yan Hao Peng suggested that China's shipbuilding cutting technology and equipment should be towards flexible, digital, integrated direction. Ship prices at the time of the introduction of advanced cutting technology, should focus its cutting speed, groove quality and deformation values to meet the subsequent assembly quality and weld quality requirements of the workpiece.
