電(dian)(dian)(dian)阻(zu)(zu)(zu)焊(han)(han)的特點1：電(dian)(dian)(dian)阻(zu)(zu)(zu)焊(han)(han)是利用焊(han)(han)件內部產生的電(dian)(dian)(dian)阻(zu)(zu)(zu)熱(re)從高溫(wen)區傳導到(dao)低溫(wen)區，加熱(re)熔化金(jin)(jin)(jin)屬而實現焊(han)(han)接(jie)。屬于內部分布式能源(yuan)。2：電(dian)(dian)(dian)阻(zu)(zu)(zu)焊(han)(han)的焊(han)(han)縫在(zai)壓力(li)作用下凝固(gu)或(huo)聚集結晶，屬于壓力(li)焊(han)(han)的范疇，具有鍛(duan)造(zao)的特點。3：由于焊(han)(han)接(jie)熱(re)集中，加熱(re)時間短，熱(re)影響區小，焊(han)(han)接(jie)變形和應(ying)力(li)也小。因此(ci)，通常焊(han)(han)后不需要(yao)校(xiao)正和熱(re)處理。4：一般不需要(yao)焊(han)(han)接(jie)、焊(han)(han)絲(si)、焊(han)(han)劑、保護氣體等焊(han)(han)接(jie)材料，焊(han)(han)接(jie)成本(ben)低。5：電(dian)(dian)(dian)阻(zu)(zu)(zu)焊(han)(han)的熔核始終被固(gu)態金(jin)(jin)(jin)屬包圍，熔融金(jin)(jin)(jin)屬與(yu)空氣隔絕，焊(han)(han)接(jie)冶金(jin)(jin)(jin)過(guo)程(cheng)比(bi)較(jiao)簡單。電(dian)(dian)(dian)阻(zu)(zu)(zu)焊(han)(han)電(dian)(dian)(dian)極(ji)(ji)的優點與(yu)缺點?河(he)南(nan)制(zhi)造(zao)電(dian)(dian)(dian)阻(zu)(zu)(zu)焊(han)(han)電(dian)(dian)(dian)極(ji)(ji)
