The outer layer of aluminum oxide film pattern in contact with the electrolyte chemical dissolution. General requirements for the first organic solvent (e.g., kerosene, gasoline, trichlorethylene, carbon tetrachloride, etc.) of crude degreased, and then transferred to the chemical degreasing. Good thermal stability of the aluminum alloy profiles, at 300 ~ 500 ℃ condition, its strength is about 10 times higher than aluminum. The main reason is the high porosity joints, weld quality requirements can not be satisfied. It is widely used in various industries. This film is formed early enough fine embossed aluminum oxide factory in Jinan, although some resistance, but the negative oxygen ions in the electrolyte can still reach the surface continues to form an aluminum oxide film pattern aluminum application in life are more common, and traditional sheet compared to aluminum patterns having a light weight, high strength, good corrosion resistance and other characteristics of the current pattern is widely used in a variety of welding aluminum structure products. Now, Xiao Bian and introduce simple pattern aluminum welding problems. 1 . linear expansion coefficient Jinan embossed aluminum oxide, prone to the phenomenon of welding deformation. 2. The large thermal conductivity of aluminum alloy, the same welding speed, heat input is larger. 3. The welded joints soften embossed aluminum oxide, the strength coefficient low. The weld prone to porosity. 5. The welding is easy to produce a refractory oxide film 6. The alloy surface thermal cracks prone. these are a few problems often encountered during the welding of aluminum patterns, we are here your list is a reminder, and make timely appropriate measures to avoid! oxidized embossed aluminum, embossed aluminum oxide factory in Jinan, rolls Alcoa (certified merchants) are provided by Jinan Heshun Aluminium Limited.
