Due to certain characteristics of aluminum, making aluminum and steel welding different welding process, is compared with the non-ferrous metals in copper, also has its differences, in order to smooth welding, you should understand the impact of aluminum on the welding process. 1, the chemical properties of the active aluminum and aluminum is very easy to generate oxygen in the air layer of insoluble aluminum oxide film covering the surface of the aluminum plate, a melting point of 2050 ℃. The melting point of aluminum is 657 ℃, when the aluminum melting Shandong Aluminum Which is good reputation, aluminum melting temperature is far away, and density. Therefore, in the welding process, the alumina film on the surface of aluminum plate is difficult to remove, affect the welding. 2, aluminum thermal conductivity and specific heat large aluminum thermal conductivity and specific heat ratio more than doubled Jinan big stick aluminum Which is good reputation, although the low melting point of aluminum, but there must be a high concentration of heat and enough heat, to make aluminum curtain wall aluminum welding is widely used in construction, with good insulation effect, saving energy Jinan reputable manufacturers of aluminum and excellent decorative effect. Single curtain from the selection of materials, through the material itself to achieve certain energy savings. Emergence of the respiratory ventilation layer curtain wall to save cooling costs in summer, winter can save on heating costs. Blinds placed ventilation layer, can effectively prevent the sun without affecting facades. Outer glass curtain wall aluminum chosen colorless transparent glass or low reflective glass, can minimize the adverse effects caused by the reflection of glass, the glass is generally used in a certain reflection coated glass Jinan reputable manufacturers of aluminum rolls _ _ Alcoa aluminum Aluminum Ltd. provided by Jinan rolls. Jinan Heshun Aluminum Co. (www.jnhsly.com) strong, credible, in Jinan, Shandong aluminum products industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead rolls in aluminum and you hand into the brilliant, for a better future!
