[summary] solder one of crucial technologies that the technology makes as shipping, affect the quality that produces to shipping and cost directly. Gas property mixes the report that inversion welder stabilizes with its to solder goodly the effect becomes shipping welder the inevitable choice of course of study, accordingly we should popularize inversion welder energetically, promote the development of Chinese shipping manufacturing industry. Shipbuilding industry is called " face deep-sea equipment line of business " , basically offer boats and ships of big punishment ore and crude oil ship, large container to wait to did not have. Current, shipbuilding industry is the trade that our country processes the only in industry to be able to walk along alive bound front row again. 2007, finishing gross is our country shipbuilding 18.93 million T, continue to hold alive group the 3rd. World abundant wanted 1 ～ April 2008 index of 3 big shipbuilding expresses shipbuilding nation and area as follows be shown. Nation of world main shipbuilding mixed 1 ～ April 2008 area data sources of index of 3 big shipbuilding: British carat overcomes soft company to study a report. From inside the watch we can discover, 2008 1 ～ April, inside same time, I am over with shipbuilding on measure what appearance has Han Youhe Japan to make an appointment with L/2. Data makes clear, be in shipbuilding of year of average per capita ton number, year production value of average per capita and manufacturing efficiency on 3 main index, the 3 ～ that Korea and Japan are China probably 5 times. The productivity of industry of our country shipping rises urgently, this depends on the development of all sorts of technologies in shipbuilding and perfect. Soldering is one of crucial technologies of project of modern boats and ships, hull is occupied to build the 40 ％ of total man-hour about when hull welder, solder the 40 ％ of 30 ％ ～ that cost occupies hull to make totle drilling cost about. Shipping solders technical level and manufacturing efficiency are to affect shipping to build periodic, ox to produce the main factor of quality of cost, product. Accordingly, develop high-tech standard solder equipment is had to the progress of manufacturing industry of our country shipping urge action tremendously. Current, solder in domestic shipping the industry basically applies CO2, the aeriform protection solder, solder that bury arc and welding rod arc welding 3 kinds of methods. Among them CO2, gas rests protective solder application is most, it is marine the way that welder extends energetically; The solder that bury arc is multi-purpose at board long welding line solders, dosage is stabilized basically; Welding rod arc welding applies scale to drop substantially. According to not complete interconnected system, to 2007, gas of the CO2 in backbone dockyard protects solder scale to achieve 60 ％ , welding rod arc welding occupies 20 ％ about, the solder that bury arc occupies 10 ％ about, the rest is other type welder. The electric property that inversion welder has stability and solder goodly the effect, it is current most advanced welder. Inversion welder had received large-scale application in general industry, but the applied scale in dockyard is uneven. In backbone dockyard, inversion welder begins to receive promotion application, among them NBC - 500 model CO2 welder, MZ - 1000 model bury arc welding machine and ZX7 manual arc the application of amphibious welder is most wide. The performance that inversion welder exceeds with its report becomes shipping to solder the inevitable choice of manufacturing industry, but compare with photograph of international developed country, our inversion welder utilization rate is lower. Accordingly, still need to popularize inversion welder energetically especially be hungry of IGBT inversion solder, ability holds shipping to solder technical commanding elevation, urge our country effectively by the transition of shipbuilding big country to shipbuilding powerful nation.
