即使是焊接性良好的焊接件，深孔焊機的(de)焊(han)(han)(han)(han)接(jie)(jie)表面(mian)(mian)(mian)也(ye)應保(bao)持清潔。由于長(chang)期存放、污染(ran)等(deng)原因(yin)，焊(han)(han)(han)(han)接(jie)(jie)件(jian)(jian)表面(mian)(mian)(mian)可能(neng)會(hui)(hui)(hui)產生(sheng)有害的(de)氧(yang)化膜、油污等(deng)。因(yin)此，焊(han)(han)(han)(han)接(jie)(jie)前應清潔表面(mian)(mian)(mian)，否則難以保(bao)證(zheng)質量。深孔焊(han)(han)(han)(han)機(ji)焊(han)(han)(han)(han)接(jie)(jie)可靠(kao)，保(bao)證(zheng)導(dao)電(dian)性能(neng)，確保(bao)焊(han)(han)(han)(han)點導(dao)電(dian)性能(neng)良好，防止(zhi)誤(wu)焊(han)(han)(han)(han)。假(jia)焊(han)(han)(han)(han)接(jie)(jie)是指焊(han)(han)(han)(han)料和待焊(han)(han)(han)(han)接(jie)(jie)物體(ti)表面(mian)(mian)(mian)之間(jian)(jian)(jian)沒(mei)有形(xing)成(cheng)合(he)金(jin)(jin)(jin)結構，但(dan)它(ta)們只(zhi)是附著(zhu)在待焊(han)(han)(han)(han)接(jie)(jie)金(jin)(jin)(jin)屬表面(mian)(mian)(mian)上。焊(han)(han)(han)(han)接(jie)(jie)時(shi)，如(ru)果只(zhi)有部分零(ling)(ling)件(jian)(jian)形(xing)成(cheng)合(he)金(jin)(jin)(jin)，其余零(ling)(ling)件(jian)(jian)不形(xing)成(cheng)合(he)金(jin)(jin)(jin)，這(zhe)種焊(han)(han)(han)(han)點也(ye)可以在短(duan)時(shi)間(jian)(jian)(jian)內通過(guo)電(dian)流(liu)，用儀(yi)器(qi)測量很(hen)難發現(xian)問(wen)題。然而(er)，隨著(zhu)時(shi)間(jian)(jian)(jian)的(de)推移，沒(mei)有合(he)金(jin)(jin)(jin)的(de)表面(mian)(mian)(mian)會(hui)(hui)(hui)被氧(yang)化。此時(shi)，會(hui)(hui)(hui)出(chu)現(xian)開關(guan)現(xian)象，這(zhe)將不可避免地導(dao)致(zhi)產品質量問(wen)題。

深孔焊機的溫差因素和周期應合理。當電弧激光電焊加工被不光滑加熱時，應將焊料和待電弧激光電焊加工金屬加熱至電弧激光電焊加工溫差因素，無誤鋁熱反應的焊料可能浸潤并對外外擴散到待電弧激光電焊加工金屬從表面上，養成金屬氧化物。由此，肯定能提供合理的電弧激光電焊加工溫差因素，以確認電弧激光電焊加工點經久耐用。在已經能高的溫差因素下，焊料能截然性潤濕并截然性對外外擴散以養成硬質合金層。溫差因素過高有印象于電弧激光電焊加工。電弧激光電焊加工周期對焊料的潤濕性、電弧激光電焊加工元器件封裝和結合層的養成有太大印象。充分電弧激光電焊加工的主要是準確的理解電弧激光電焊加工周期。
