the application of welding materials

The sudden emergence in recent years the application of flux cored wire, due to high deposition efficiency flux cored wire with a seam of good quality, low spatter, easily mechanized and automated welding. Currently the shipyard has been widely used flux cored wire for welding ship structures.

At the same time it with the CO2 welding technology combine to   make the shipyard have tasted the sweetness in production, so the current number of shipyards that CO2 gas shielded flux cored wire welding is a major shipyard welding and welding materials. Were tested next year of its application
cable trays installation
Significant growth trend, Table 2.
Promote the use of the large number of CO2 gas shielded flux cored wire, thus greatly improving the daily per capita consumption of shipyard welders amount of welding material, as shown in Table 3. This further reduces the cost of shipbuilding, ship construction period shortened.

In addition, the construction of some high value-added and non-vessel shipping products (such as a large steel structure high-rise building large bridges, etc.) of the welding technology has also created many innovative welding technology, has made great economic and social benefits.
    2 and the gap between Japan and Korea
China's shipbuilding technology with Japan, South Korea, there still exist between the large gap. Advantage of low wages shipbuilding labor productivity is a huge gap between the offset, shipbuilding materials, equipment costs were higher than in Japan, South Korea. China's shipbuilding enterprises are small

And scattered, poor economies of scale, coupled with inadequate investment in scientific research, not yet formed a reasonable and effective system of scientific and technological gap between technological innovation has not only significantly reduced, in some places but to expand in China, Japan, South Korea 3 National shipbuilding and welding technology indicators such as

Table 4.
China's accession to WTO on China's shipbuilding industry organizations is a great, the challenge is to expand the opening up of its substance, so that the trend of the shipbuilding industry into the world economy, the deeper into the market to international competition, became the world shipbuilding industry the present

Reality. And to the shipbuilding industry's largest and   most realistic and most severe challenge is technological innovation, construction of high-tech and high added value ships is the focus of future international market, but also compete for shipbuilding areas of the country.
