按 GB/T3190 — 1996 和GB/T16474— 1966 的規(guī)定,鋁合金牌號(hào)命名的基本原則是:可直接采用國(guó)際四位數(shù)字體系牌號(hào)。 合金是有兩種或兩種以上的金屬元素與非金屬元素所組合成的具有 合金性質(zhì)的物質(zhì)。鋁合金的廣泛應(yīng)用促進(jìn)了鋁合金焊接技術(shù)的發(fā)展,同時(shí)焊接技術(shù)的發(fā)展又拓展了鋁合金的應(yīng)用領(lǐng)域,因此鋁合金的焊接技術(shù)正成為研究的熱點(diǎn)之一。 關(guān)鍵詞: 鋁及鋁合金 手工氬弧焊 焊接特點(diǎn) 2 Abstract Aluminum and aluminum alloy is the most widely used in industry of a class of nonferrous metal structure material, in aviation, aerospace, automotive, machinery manufacturing, shipping and the chemical industry has a large application. Recent years, with science and technology and industrial economic development, to the aluminum alloy welding structure of the increasing demand, the aluminum alloy welding sex research will be further. The wide application of aluminum alloy aluminum alloy welding technology promoted the development, and welding technology development and expand the application field of aluminum alloy, aluminum alloy welding
