| Development and application of welding materials with the needs of national economic construction and the development of scientific and technological progress spear D, the thin electrode in the 1920s, the thick electrode 30s, 40s automatic submerged arc welding, the 1950s CO :, gas shielded solid wire and 70 years after the gas shielded flux cored wire, welding materials are described in the continuous development, therefore welding position in the welding material increasingly being challenged. But in the country still has a crucial role rod, still holds a 65% to 75% of welding materials, welding production enterprises located in various regions except Tibet, under the machinery and metallurgy, energy. Shipbuilding sectors, agriculture and other economic types are state-owned, collective, private, joint ventures, wholly-owned, joint-stock, foreign. Welding industry has experienced in 1992 and 1993, the benefits of the peak period, due to a sharp increase in production of enterprises, resulting in rapid increase in production capacity, production continues to increase, resulting in declining prices of ordinary goods, dramatically reducing the margin to welding without profit or loss, as some groups have a relatively strong advantage. Domestic and foreign enterprises in the face of competition, large welding materials enterprises have set up research and development, in a favorable position to enhance the market plays an important role, on the other hand, some companies use the advanced management mode, these measures a enterprises to improve their strength and competitiveness has a very important significance. |
