Aluminum smelting and casting is the casting of the main link. Strictly control the whole process of melting and casting, wire and cable, Jiangsu recovery, to prevent pinholes, inclusions, due to cast, cracks, holes and casting defects such as shrinkage plays an important role. Since aluminum melts hydrogen absorption tendency of large, strong oxidizing power, easily dissolved iron, must take simple but sensible precautions in smelting and casting process, in order to obtain high-quality castings. Cast aluminum in cars is widely used, 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, Hunan wire and cable recycling, 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 the small cold weld heat-affected zone, Hubei wire and cable recycling, will not cause deformation of the substrate annealing, wire and cable recycling, 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.
