擴散焊的接頭形式設計，擴散焊接頭的形式比熔化焊類型多，可進行復雜形狀的接合，如平板、圓管、中空、T形及蜂窩結構均可進行擴散焊。焊件表面的制備與清理待焊表面狀態(tài)對擴散焊接過程和接頭質量的影響很大，特別是固態(tài)擴散焊，必須在裝焊前對焊件表面進行認真準備，其表面準備包括：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、水或有機物膜層。表面機械加工，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，利于縮短均勻化擴散的時間。過厚的中間層焊后會以層狀殘留在界面區(qū)，影響接頭的物理、化學和力學性能。中間層厚度在30~100μm時，以箔片的形式夾在待焊接表面間。

工藝參數(shù)對焊接質量的影響，創(chuàng)闊金屬多年經驗分析，并能很好掌控技術，一，焊接溫度，焊接溫度越高，擴散系數(shù)越大，金屬的塑性變形能力越好，焊接表面達到緊密接觸所需的壓力越小，所獲得的接頭強度越高。但是，加熱溫度的提高要受到被焊材料的冶金和物理化學特性方面的限制，如再結晶、低熔共晶和金屬間化合物的生成等，此外，提高加熱溫度還會造成母材軟化，這些變化直接或間接地影響到擴散焊接過程及接頭的質量。因此，當溫度高于某一限定值后，再提高加熱溫度時，擴散焊接頭質量不*得不到提高，甚至反而有所下降。不同材料組合的焊接接頭，應根據(jù)具體情況，通過實驗來確定焊接溫度。二，焊接壓力，擴散焊接時施加壓力的主要作用是促使焊件表面產生塑性變形并達到緊密接觸狀態(tài)，使界面區(qū)原子，加速擴散與界面孔洞的彌合及消失，防止擴散孔洞的產生。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，在擴散焊的階段焊接表面無法達到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)榻缑婵锥础Ｒ虼?，在加壓變形階段，就要設法使絕大部分焊接表面達到緊密接觸狀態(tài)。換熱器螺旋板</p><p
