Extrusion barrel temperature irrational choices will affect the quality of the weld aluminum tee Which is good, for thick-walled tube extrusion temperature profiles proposal 440-460 ℃, and for thin-walled profiles and shunt hole is too large in the case of aluminum Tee Manufacturers, suggested the use of 400-420 ℃, on the other hand, squeeze tube is not clean, more coproduct scale or squeeze tube is deformed as the drum, as well as squeeze tube and squeeze the pad gap is too large, These all affect the weld quality. Mechanical cleaning: In the workpiece size larger, longer production cycle, multi-layer welding or chemical contamination after cleaning aluminum tee supply manufacturers, often using mechanical cleaning. With acetone, gasoline and other organic solvents to wipe the surface of the oil, and then directly with a diameter of 0.15 mm ~ 0.2 mm stainless steel wire brush or wire brush, brush the exposed metallic luster so far. Generally should not use the wheel or ordinary sandpaper, so as not to leave the metal surface sand into the pool generated during welding slag and other defects. There is also available scraper, rasp and other clean up the surface to be welded. Aluminum tee manufacturers _ cis Aluminum (certified) _ aluminum tee provided by the Aluminum Co., Ltd. Jinan rolls.
