style="text-indent:25px">對于有些封頭來說，常常會用到電阻焊接工藝來進行加工處理，不過在使用這種技術(shù)時有些常識是需要大家了解的，下面將具體的為您講解。封頭電阻焊熔核形成時，始終被塑性環(huán)包圍，熔化金屬與空氣隔絕，冶金過程簡單。加熱時間短，熱量集中，故熱影響區(qū)小，變形與應(yīng)力也小，通常在焊后不必安排校正和熱處理工序。而焊接時，封頭焊后一般都會產(chǎn)生變形，如果變形量超過允許值，就會影響使用，產(chǎn)生的主要原因是焊件不均勻地局部加熱和冷卻，因為焊接時，焊件*在局部區(qū)域被加熱到高溫，離焊縫愈近，溫度愈高，膨脹也愈大。因此，當封頭和電極已定時，封頭的電阻取決于它的電阻率。而電阻率是被焊材料的重要性能，所以電阻率高的金屬其導(dǎo)熱性差(如不銹鋼)，電阻率低的金屬其導(dǎo)熱性好(如鋁合金)。總之，點焊不銹鋼時產(chǎn)熱易而散熱難，點焊鋁合金時產(chǎn)熱難而散熱易。南通臥式儲罐封頭廠家</p><p
