In 2005, China's steel output was 349 million tons, accounting for 30.9% of the world's steel output of 1.13 billion tons, welding production of about 270 million t, accounting for about 50% of the world's total output of more than 500 million tons of welding consumables.
    China's steel consumption in 2006 will be about 400 million t, welding production will be 3 million t. According to the relevant departments predicted that China's steel consumption in 2010 will be more than 500 million t, the corresponding consumption of welding materials will reach 3.5 million t or so. So our country has become the world's only consumable materials consumption power. Domestic welding consumables industry has been rapid development, foreign welding consumables enterprises have also through the output of products, provide technical services and set up factories in China and other ways to compete for the market.
 
    Fierce competition in the market shows that low profit ordinary welding materials, such as knot 422 electrode, ER50-6 gas shielded wire, HJ431 flux and other products, mainly between domestic enterprises competition; and high technical content, profits are also larger All kinds of domestic welding consumables enterprises in the competition at a disadvantage, there is a big gap, so we must pay attention to the future development of China's welding consumables national industry.
