擴(kuò)散焊的接頭形式設(shè)計(jì)，擴(kuò)散焊接頭的形式比熔化焊類型多，可進(jìn)行復(fù)雜形狀的接合，如平板、圓管、中空、T形及蜂窩結(jié)構(gòu)均可進(jìn)行擴(kuò)散焊。焊件表面的制備與清理待焊表面狀態(tài)對(duì)擴(kuò)散焊接過(guò)程和接頭質(zhì)量的影響很大，特別是固態(tài)擴(kuò)散焊，必須在裝焊前對(duì)焊件表面進(jìn)行認(rèn)真準(zhǔn)備，其表面準(zhǔn)備包括：加工符合要求的表面粗糙度、平面度，去除表面的氧化物，消除表面的氣、水或有機(jī)物膜層。表面機(jī)械加工，表面凈化處理。中間層的選用，可采用箔、粉末、鍍層、離子濺射和噴涂層等多種形式。厚度一般為幾十微米，利于縮短均勻化擴(kuò)散的時(shí)間。過(guò)厚的中間層焊后會(huì)以層狀殘留在界面區(qū)，影響接頭的物理、化學(xué)和力學(xué)性能。中間層厚度在30~100μm時(shí)，以箔片的形式夾在待焊接表面間。 </p>擴(kuò)散焊的特點(diǎn)及分類： <p> 可焊材料多，擴(kuò)<span style="font-size:12px;">散焊接時(shí)因基體不過(guò)熱、不熔化，可以在不降低被焊材料性能的情況下焊接幾乎所有的金屬或非金屬，特別適合于熔焊和其他方法難以焊接的材料，如活性金屬、耐熱合金、陶瓷和復(fù)合材料等。對(duì)于塑性差或熔點(diǎn)高的同種材料，以及不互溶或在熔焊時(shí)會(huì)產(chǎn)生脆</span> </p> <p> 性金屬間化合物的異種材料，擴(kuò)散焊是一種可靠的焊接方法。擴(kuò)散焊接頭質(zhì)量好，其顯微和性能與母村接近或相同，焊縫無(wú)熔焊缺點(diǎn)，無(wú)過(guò)熱和熱影響區(qū)。焊接參數(shù)易于精確控制，在批量生產(chǎn)時(shí)接頭質(zhì)量和性能隱定。 </p> <p> 因焊接時(shí)所加壓力較小，工件多是整體加熱，隨爐冷卻，故焊件整體塑性變形很小，焊后的工件一般不再進(jìn)行機(jī)械加工。 </p> <p> 因焊接所需壓力不大，故大斷面焊接所需設(shè)備的噸位不高，易于實(shí)現(xiàn)。 </p> <p> 可以焊接結(jié)構(gòu)復(fù)雜、接頭不易接近以及厚薄相差較大的工件，能對(duì)組裝件中許多接頭同時(shí)實(shí)施焊接。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> <br

工藝參數(shù)對(duì)焊接質(zhì)量的影響，創(chuàng)闊金屬多年經(jīng)驗(yàn)分析，并能很好掌控技術(shù)，一，焊接溫度，焊接溫度越高，擴(kuò)散系數(shù)越大，金屬的塑性變形能力越好，焊接表面達(dá)到緊密接觸所需的壓力越小，所獲得的接頭強(qiáng)度越高。但是，加熱溫度的提高要受到被焊材料的冶金和物理化學(xué)特性方面的限制，如再結(jié)晶、低熔共晶和金屬間化合物的生成等，此外，提高加熱溫度還會(huì)造成母材軟化，這些變化直接或間接地影響到擴(kuò)散焊接過(guò)程及接頭的質(zhì)量。因此，當(dāng)溫度高于某一限定值后，再提高加熱溫度時(shí)，擴(kuò)散焊接頭質(zhì)量不僅得不到提高，甚至反而有所下降。不同材料組合的焊接接頭，應(yīng)根據(jù)具體情況，通過(guò)實(shí)驗(yàn)來(lái)確定焊接溫度。二，焊接壓力，擴(kuò)散焊接時(shí)施加壓力的主要作用是促使焊件表面產(chǎn)生塑性變形并達(dá)到緊密接觸狀態(tài)，使界面區(qū)原子，加速擴(kuò)散與界面孔洞的彌合及消失，防止擴(kuò)散孔洞的產(chǎn)生。壓力越大，溫度越高，緊密接觸的面積也越大，但不管壓力多大，在擴(kuò)散焊的階段焊接表面無(wú)法達(dá)到100％的緊密接觸狀態(tài)，總有一小部分局部未接觸的區(qū)域演變?yōu)榻缑婵锥?。因此，在加壓變形階段，就要設(shè)法使絕大部分焊接表面達(dá)到緊密接觸狀態(tài)。不銹鋼篩筒</p><p
