Aluminum tube feeding through wire wheel, tip conductive aluminum tube between the base metal and the welding arc, aluminum tube welding wire and base metal melting, and with an inert gas such as argon shielded arc and the molten metal to be welded . It TIG difference: one is the wire for the electrode, and is constantly filled with the molten bath Stone manufacturer specializing in the production of aluminum, formed weld condensed; the other is to protect the gas, along with MGAW The four aluminum factory in Jinan technology, protection of argon gas from a single development of a variety of widely mixed gas, such as Ar80% + CO220% argon-rich shielding gas. The former is usually referred to as MIG Shandong Aluminum Stone price, which is called MAG. In view of its mode of operation, currently the most widely used is the semi-automatic MIG welding and argon-rich mixed gas shielded arc welding, followed by automatic TIG welding. MIG and TIG welding aluminum four compared with the following characteristics. (1) High-efficiency aluminum tube because it current density, heat concentration, deposition rate and welding speed. In addition, easy arc. (2) The need to strengthen the protective aluminum tube because arc strong, big smoke, so to strengthen protection. Stress factors include load type, load size, load direction, the load speed, etc. on the SCC, the stress direction perpendicular to the grain boundaries must be to be able to separate one of the key factors is the need for stress corrosion stress And different stresses may produce different results, alternating stress and the environment together to produce corrosion fatigue, stress corrosion it and fixed stress fracture usually a clear distinction between consequences of corrosion fatigue than usual stress corrosion produced more serious. In addition Different loading speed will also affect the sensitivity to stress corrosion of aluminum alloy aluminum four professional manufacturers, rolls aluminum, aluminum Stone provided by Jinan Heshun Aluminium Limited. Jinan Heshun Aluminum Co., Ltd. (www.jnhsly.com) (www.jnhsly.cn) Shandong Jinan, aluminum products leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer demand. Aluminum in Heshun leadership with the staff warmly welcome all inquiries negotiations to create a better future for aluminum rolls.
