Aluminum is the industry's most widely used non-ferrous structural materials production of non-national standard aluminum ingots, have been widely used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding aluminum and chemical industries. Major alloying elements are copper, silicon, magnesium, zinc, manganese, minor alloying elements are nickel, iron, titanium, chromium, lithium and so on. Cast aluminum industry has developed rapidly, as of 2011, the Department of renewable cast aluminum output has reached 4.28 million tons, and then the native system cast aluminum output rose to 1.84 million tons. With the global economic growth and expanding use of aluminum, global consumption of aluminum increased from about 8.69 million tons in 2001 to about 15.5 million tons in 2009 GB ingot manufacturers, the annual compound growth rate of about 7.5 percent. 2012, global aluminum consumption will reach about 16.69 million tons. June 2012, China exported 41,102 tons of aluminum ingots, up 21.53 percent reduction in 2011, the ring than 20.86 percent decrease in May, up the chain there are the more obvious decline. Cast aluminum in cars is widely used aluminum ingots, such as the engine cylinder head, intake manifold, pistons, wheels, steering booster housing and so on. Bug fixes aluminum in the production process, prone to shrinkage, trachoma, pores and slag and other casting defects. How to repair aluminum alloy casting porosity and other defects it? If welding, TIG welding equipment to repair, since the heat capacity, prone to side effects such as thermal deformation, can not meet the welding requirements. Cold welding repair machine is to use a high-frequency spark spark, no heat welding to repair casting defects principle. Due to cold welding heat affected zone of small GB ingots suppliers, will not cause deformation of the substrate annealing, no cracks, no hard spots, hardening. And high weld strength, fill material and the substrate simultaneously re-solidification after melting, combined with a solid, can be grinding, milling, filing and other processing, compact does not fall off. Cold welding repair machine is the ideal way to repair aluminum porosity, trachoma and other small defects.
