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)的導向（排除特殊行業(yè)），當然了現(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。線材表面亦需光滑平順且清潔否則將影響送絲的順暢及焊接電流的傳迅。江蘇日亞焊條焊絲供應商</p><p
