1．電(dian)(dian)(dian)(dian)弧(hu)(hu)焊(han)(han)(han)(han)(han)(han)(han)電(dian)(dian)(dian)(dian)弧(hu)(hu)焊(han)(han)(han)(han)(han)(han)(han)是目前應用(yong)(yong)廣泛的(de)焊(han)(han)(han)(han)(han)(han)(han)接方法。它包括有：手弧(hu)(hu)焊(han)(han)(han)(han)(han)(han)(han)、埋弧(hu)(hu)焊(han)(han)(han)(han)(han)(han)(han)、鎢(wu)極氣體(ti)保護電(dian)(dian)(dian)(dian)弧(hu)(hu)焊(han)(han)(han)(han)(han)(han)(han)、等(deng)離(li)子弧(hu)(hu)焊(han)(han)(han)(han)(han)(han)(han)、熔(rong)(rong)(rong)化極氣體(ti)保護焊(han)(han)(han)(han)(han)(han)(han)等(deng)。絕(jue)大部分電(dian)(dian)(dian)(dian)弧(hu)(hu)焊(han)(han)(han)(han)(han)(han)(han)是以(yi)(yi)電(dian)(dian)(dian)(dian)極與(yu)工件之間燃燒的(de)電(dian)(dian)(dian)(dian)弧(hu)(hu)作熱源(yuan)。在形成接頭時，可以(yi)(yi)采(cai)(cai)用(yong)(yong)也可以(yi)(yi)不采(cai)(cai)用(yong)(yong)填充(chong)金屬。所(suo)用(yong)(yong)的(de)電(dian)(dian)(dian)(dian)極是在焊(han)(han)(han)(han)(han)(han)(han)接過(guo)程中(zhong)熔(rong)(rong)(rong)化的(de)焊(han)(han)(han)(han)(han)(han)(han)絲時，叫作熔(rong)(rong)(rong)化極電(dian)(dian)(dian)(dian)弧(hu)(hu)焊(han)(han)(han)(han)(han)(han)(han)，諸如手弧(hu)(hu)焊(han)(han)(han)(han)(han)(han)(han)、埋弧(hu)(hu)焊(han)(han)(han)(han)(han)(han)(han)、氣體(ti)保護電(dian)(dian)(dian)(dian)弧(hu)(hu)焊(han)(han)(han)(han)(han)(han)(han)、管狀焊(han)(han)(han)(han)(han)(han)(han)絲電(dian)(dian)(dian)(dian)弧(hu)(hu)焊(han)(han)(han)(han)(han)(han)(han)等(deng)；所(suo)用(yong)(yong)的(de)電(dian)(dian)(dian)(dian)極是在焊(han)(han)(han)(han)(han)(han)(han)接過(guo)程中(zhong)不熔(rong)(rong)(rong)化的(de)碳(tan)棒(bang)(bang)或鎢(wu)棒(bang)(bang)時，叫作不熔(rong)(rong)(rong)化極電(dian)(dian)(dian)(dian)弧(hu)(hu)焊(han)(han)(han)(han)(han)(han)(han)，諸如鎢(wu)極氬弧(hu)(hu)焊(han)(han)(han)(han)(han)(han)(han)、等(deng)離(li)子弧(hu)(hu)焊(han)(han)(han)(han)(han)(han)(han)等(deng)。

（1）手弧焊

手弧(hu)焊(han)(han)是各種(zhong)電弧(hu)焊(han)(han)方(fang)法中(zhong)(zhong)發(fa)展早、目前仍然應(ying)用(yong)廣(guang)的(de)一(yi)種(zhong)焊(han)(han)接(jie)方(fang)法。它是以外部(bu)涂有(you)涂料的(de)焊(han)(han)條(tiao)作(zuo)(zuo)電極和填充金(jin)(jin)(jin)屬(shu)，電弧(hu)是在(zai)(zai)焊(han)(han)條(tiao)的(de)端(duan)部(bu)和被(bei)焊(han)(han)工件表面之間燃燒。涂料在(zai)(zai)電弧(hu)熱作(zuo)(zuo)用(yong)下(xia)一(yi)方(fang)面可(ke)(ke)以產生(sheng)(sheng)(sheng)氣體(ti)(ti)以保(bao)護(hu)電弧(hu)，另一(yi)方(fang)面可(ke)(ke)以產生(sheng)(sheng)(sheng)熔渣覆蓋在(zai)(zai)熔池表面，防止熔化金(jin)(jin)(jin)屬(shu)與周圍(wei)氣體(ti)(ti)的(de)相互作(zuo)(zuo)用(yong)。熔渣的(de)更重要作(zuo)(zuo)用(yong)是與熔化金(jin)(jin)(jin)屬(shu)產生(sheng)(sheng)(sheng)物理化學反應(ying)或添加合金(jin)(jin)(jin)元素，改善焊(han)(han)縫金(jin)(jin)(jin)屬(shu)性(xing)能。手弧(hu)焊(han)(han)設(she)備簡(jian)單、輕便，操(cao)作(zuo)(zuo)靈活。可(ke)(ke)以應(ying)用(yong)于(yu)維修及裝(zhuang)配(pei)中(zhong)(zhong)的(de)短縫的(de)焊(han)(han)接(jie)，特別是可(ke)(ke)以用(yong)于(yu)難以達到的(de)部(bu)位的(de)焊(han)(han)接(jie)。手弧(hu)焊(han)(han)配(pei)用(yong)相應(ying)的(de)焊(han)(han)條(tiao)可(ke)(ke)適用(yong)于(yu)大(da)多數工業用(yong)碳(tan)鋼(gang)、不銹鋼(gang)、鑄(zhu)鐵、銅(tong)、鋁、鎳及其合金(jin)(jin)(jin)。
