Welding and cutting is one of the most critical production technologies in the shipbuilding industry. Welding, cutting and quality inspection equipment are also the main process equipment for shipbuilding enterprises. During the 2008 China Shipbuilding Industry International Summit Forum, the Advanced Shipbuilding Welding and Quality Inspection Technology Forum was the focus of the shipbuilding industry. Welding: Focus on more efficiency Chen Jiaben, director of the China Welding Association Shipbuilding Professional Committee, gave a report on "Progress in China's Ship Welding Technology" at the forum. According to him, the application rate of CO2 gas protection semi-automatic welding technology is currently 60%-65% in China's shipbuilding enterprises. More than 40 shipbuilding welding methods have been applied to the construction of various types of ships; welding workers are all welding materials day in the shipbuilding industry. The consumption is up to 15 kg, the use of single-sided welding pads is 700,000 meters, and the application rate of high-efficiency and energy-saving welding equipment is over 95%. Advanced high-efficiency welding technology has played an important role in improving shipbuilding efficiency, reducing shipbuilding costs and improving shipbuilding quality. Chen Jiaben pointed out that in the field of ship welding equipment and materials, a large number of advanced welding materials and equipment have been localized, and rectified AC/DC arc welding machines and inverter arc welding machines have been continuously developed and applied. At the same time, in order to meet the requirements of energy conservation and environmental protection, China's major backbone ship companies have eliminated acetylene gas with high energy consumption and serious pollution, and replaced it with propane liquefied petroleum gas and natural gas. The low-toxic and low-dust electrode has been further promoted. Inverter welding power supplies are replacing high-energy rotary arc welding power supplies. Although the application of laser welding technology in China's shipbuilding industry is not blank, the high-power laser construction technology project jointly developed by China and Germany has been launched in 2005. Chen Jiaben said that in order to meet the needs of high-efficiency shipbuilding, China's welding mechanization automation rate should reach 70% at the end of the “Eleventh Five-Year Plan”, the qualification rate of welding quality will be increased by more than 5%, the welding cost will be reduced by 5%, and the welding workers will be welded daily. The consumption is increased by more than 20%. He believes that to achieve these goals, shipbuilding enterprises should adhere to the direction of regional modular construction, adhere to the refined direction of welding management, adhere to the direction of welding standardization, and adhere to the leading direction of welding research. Cutting: Pursuing the automation of Shanghai Ship Technology Research Institute senior engineer Yin Haozhen pointed out in his report "Automatic Thermal Cutting Solutions for Modern Shipbuilding Industry" that in recent years, in order to meet the needs of shipbuilding modernization, a group of advanced automated thermal cutting technologies, such as CNC flame Cutting, CNC plasma cutting, CNC pipe intersecting line cutting, robot profile automatic cutting, etc. have been introduced into the shipbuilding industry, fundamentally breaking through the bottleneck of the cutting of the ship that has plagued the ship construction cycle, and has become a boost to the rapid growth of China's shipbuilding volume. Pusher. For the application status of automated thermal cutting technology in China's shipbuilding industry, Yin Haojun said that in the aspect of sheet metal cutting, CNC plasma cutting has taken the lead, and CNC laser cutting machines have also appeared; in the aspect of pipe cutting, large and medium-sized shipping companies have adopted automation. Cutting equipment; in terms of profile cutting, only some backbone ship companies are equipped with automatic cutting equipment, and most shipbuilding companies still use manual cutting. After introducing the current development of advanced automatic cutting technology in the world shipbuilding industry, Yin Haozhen proposed that China's shipbuilding cutting technology and equipment should be developed in the direction of flexibility, digitization and integration. When introducing advanced cutting technology, shipbuilding enterprises should pay attention to their cutting speed, groove quality and deformation value to meet the subsequent assembly quality and welding quality requirements of the workpiece.
