Select welding methods and parameters are generally left welding method, welding torch and workpiece angle of 60 °. When welding thickness 15mm or more to the right welding method, welding torch and workpiece 90 ° angle. When more than 3mm wall thickness welded Jinan color coated aluminum coil manufacturers, open V-shaped groove, angle of 60 ° ~ 70 °, no larger than 1mm gap Shandong color coated aluminum coil manufacturer to complete the multi-layer welding. wall thickness of 1.5mm or less, without groove , leaving no gap, without filling wire. aluminum means the processing of aluminum and aluminum alloy plate-type material. aluminum alloy can be divided into cold-rolled and hot-rolled, the main difference is the difference between the anodic oxidation of hot-rolled aluminum You can do anodized Different cold rolled and hot-rolled aluminum uses aluminum, cold rolled aluminum sheet used for mold class, suitable for hot-rolled aluminum stamping stretch on. The same material due to different production process, its physical properties vary greatly. Aluminum also known as plastic forming, aluminum during deformation by the force and deformation mode (stress - strain state) is divided into: casting, forging, extrusion, spinning, drawing, rolling, forming (cold , deep drawing) and other processing methods Jinan color coated aluminum coil suppliers |. color coated aluminum coil | cis-cis Alcoa Aluminum Co., Ltd. is provided by Jinan.
