我公司曾加工过0.7毫米,2毫米和3毫米等不同厚度的纯铝,也加工过 LF、LY等可焊性较差的铝合金,接头形式有直缝对接焊和环缝对接焊。实践证明,只要正确而熟练地掌握了焊接工艺,是可以获得理想的焊缝。焊前准备用碱水洗去油脂。晾干后,用布擦亮焊缝两侧的边缘。薄铝板可在25%磷酸溶液中处理(一般不宜酸洗),然后用清水冲洗晾干. My company has processed 0.7 mm, 2 mm and 3 mm, such as different thickness of pure aluminum, but also processed LF, LY and other poor weldability of aluminum alloy, welded joints in the form of straight seam butt and butt weld ring. Practice has proved that as long as the correct and proficient in the welding process, is to obtain the ideal weld. Prepare for welding before using alkaline water to wash grease. After drying, use cloth to rub the edges on both sides of the weld. Thin aluminum plate can be treated in 25% phosphoric acid solution (generally should not pickling), then rinse with water.
