    • Aluminum weld wire having a nascent aluminum surface, (the weld wire is also useful for vacuum and arc metallizing), is lubricated with a dual coating of an essentially anhydrous lower alkanol and a colloidal solid lubricant each present as a layer so thin that they are essentially invisible to the naked eye. The solid lubricant is oil-free colloidal graphite which may be combined with a minor amount of a sulfide of molybdenum. The lubricant particles are deposited from a 1% to 15% by wt dispersion of the particles in the alkanol, in substantially spaced-apart relation, forming a non-uniform, monoparticulate layer on the nascent aluminum surface. The high propensity of the lubricant particles to settle out (they are smaller than 10 microns, and generally smaller than 1 micron in size) from the dispersion, permits formation of the monoparticulate layer. The alkanol layer is so thin that only from 100 ppm to 0.1% of alkanol, by weight of the weld wire, is present. Despite such minimal presence of each layer, the lubricity provided by the dual-coated weld wire is sufficient to level-layer spool the wire mechanically, substantially without human intervention. Because of such minimal presence, neither lubricant layer interferes with the welding process. When the dual-coated weld wire is spooled and sealed in a confined atmosphere provided by a hermetically sealed spool, the alkanol provides protection against oxidation of the nascent aluminum surface; and, despite being a hydrogen-containing material, the alkanol does not interfere with the high quality of the weld produced with the weld wire. Processes for using the weld wire are also disclosed.
    • 具有新生铝表面的铝焊丝(焊丝也可用于真空和电弧金属化),用基本上无水的低级链烷醇和胶体固体润滑剂的双重涂层润滑,每个呈现为薄的层, 基本上看不见肉眼。 固体润滑剂是可与少量钼的硫化物组合的无油胶体石墨。 润滑剂颗粒以基本上间隔开的关系从1%至15%重量的颗粒分散在链烷醇中沉积,在新生铝表面上形成不均匀的单一颗粒层。 润滑剂颗粒从分散体中沉降的高倾向(它们小于10微米,一般小于1微米)允许形成单组分层。 链烷醇层非常薄,仅存在按重量计的100ppm至0.1%的链烷醇。 尽管每层的这种最小的存在,双涂层焊丝提供的润滑性足以在机械上基本上没有人为的介入来对线材进行水平层卷轴。 由于这种最小的存在,润滑剂层都不会干扰焊接过程。 当双涂层焊丝缠绕并密封在由密封的阀芯提供的密闭气氛中时,链烷醇提供防止新生铝表面的氧化的保护; 并且尽管是含氢材料,但链烷醇不会干扰焊丝产生的焊缝的高质量。 还公开了使用焊丝的工艺。

    • A composition for producing aluminum casting, wrought, and welding filler metal alloys having a chemistry comprising Si varying from approximately 0.1 and 0.9 wt %,Mn varying from approximately 0.05 to 1.2 wt %, Mg varying from approximately 2.0 to 7.0 wt %, Cr varying from approximately 0.05 to 0.30 wt %, Zr varying from approximately 0.05 to 0.30 wt %, Ti varying from approximately 0.003 to 0.20 wt %, and B varying from approximately 0.0010 to 0.030 wt %, and a remainder of aluminum and various trace elements. The alloy is particularly suited to producing high strength structures such as automobiles, truck trailers, rail cars, and ships. It is the first 6xxx series weld filler metal that can be post-weld thermally treated and can weld 3xxx, 5xxx, 6xxx, and 7xxx series base alloys yielding far superior mechanical properties than those attainable from any other aluminum filler metal.
