Wire for welding materials in China's current steel standard, known as "welded steel rod or Welding Wire. The number of simultaneous growth and production of welding materials. Approximate correspondence between production and consumption of welding materials (including welding rods, wire, flux, etc.) and steel consumption.
China's apparent steel consumption is about 50 million tons in 1985, the welding material consumption was about 350,000 tons, about 26 million tons of welding wire. 1995 China's apparent steel consumption is about 100 million tons, welding material consumption is about more than 70 million tons, about 520,000 tons of welding wire
2000 China's apparent steel consumption is about 140 million tons, welding material consumption is about 1.1 million tons, about 80 million tons of welding wire. 2003 China's apparent steel consumption is about 260 million tons, welding material consumption was about 1.95 million tons, of which about 1.5 million tons: welding, use H08A and welded steel plate Treaty of 1.065 million tons, gas shielded welding wire and submerged arc welding wire about 36 tons, use ER70S-6, H11Mn2SiA, H08MnA, H10Mn2 such as welded steel plate of 365 thousand tons of the Treaty. Total use of the welding wire of about 1.43 million tons. In addition, in 2003 for the manufacture of stainless steel welding rod and welding wire of stainless steel wire, there are more than 20 thousand tons.
It should be noted that in the total Chinese production and consumption of welding materials, welding automation to enhance the level, the ratio of electrode is gradually decreased, the proportion of gas shielded welding wire is gradually increased. 1985 Welding Electrode accounted for approximately 90% of the total welding materials, electrode welding consumables total of about 75% in 2003. Expected to be accounted for welding consumables total electrode 2010
