銅鋁焊接總是經(jīng)久不衰！因為銅和鋁在工業(yè)及民用上用的場合確實太多了，加上現(xiàn)在各種工用，民用產(chǎn)品配件及設(shè)備的生產(chǎn)工藝的提高，及本著減少成本的角度考慮，銅的重量是越做越清，鋁的厚度是越做越薄，鋁替銅，銅包鋁等各式各樣的銅鋁產(chǎn)品大量涌現(xiàn)，帶給消費者的是產(chǎn)品越來越豐富，價格也越來越低，別看這其間一個很簡單的道理，但是我知道每一個產(chǎn)品的改進(jìn)或者成本的控制都凝聚了很多工藝師和技術(shù)員的艱辛努力。合理的鋁替銅已經(jīng)是一個產(chǎn)品制作與研發(fā)的導(dǎo)向（排除特殊行業(yè)），當(dāng)然了現(xiàn)在鋁焊和銅鋁焊接明顯多于純銅焊了。平時在工作中積累的銅鋁焊接的現(xiàn)場太多，雖各有特點，但總結(jié)起來卻是大同小異。每次都要做很長時間的重復(fù)工作去教使用者如何焊接銅鋁，所以現(xiàn)在將銅鋁焊接的相關(guān)的常用的都總結(jié)出來，以便每一個瀏覽者能夠快速地找到你們的***的焊接方法。此處主要介紹的是釬焊，關(guān)于熔焊可以在線交流。方法一：ALCU-Q303焊接銅和鋁說明：一種自釬氟化物藥劑的焊絲，在焊接的過程中，因為不需要使用任何的焊粉和焊劑比較受操作者的青睞，在母材的溫度達(dá)400度的情況下，用火焰的末端稍微燎一下焊絲，熔融的焊絲就會在藥粉的作用下水一般地流動。因為其非常好的流動性。</p><p>
