1．電(dian)(dian)(dian)弧(hu)(hu)(hu)(hu)(hu)焊(han)(han)(han)電(dian)(dian)(dian)弧(hu)(hu)(hu)(hu)(hu)焊(han)(han)(han)是(shi)目前應用廣泛的焊(han)(han)(han)接方法。它(ta)包括有：手(shou)弧(hu)(hu)(hu)(hu)(hu)焊(han)(han)(han)、埋弧(hu)(hu)(hu)(hu)(hu)焊(han)(han)(han)、鎢(wu)極氣體保(bao)護(hu)(hu)電(dian)(dian)(dian)弧(hu)(hu)(hu)(hu)(hu)焊(han)(han)(han)、等(deng)離(li)子弧(hu)(hu)(hu)(hu)(hu)焊(han)(han)(han)、熔(rong)化(hua)極氣體保(bao)護(hu)(hu)焊(han)(han)(han)等(deng)。絕大部分電(dian)(dian)(dian)弧(hu)(hu)(hu)(hu)(hu)焊(han)(han)(han)是(shi)以(yi)電(dian)(dian)(dian)極與(yu)工(gong)件之間燃燒的電(dian)(dian)(dian)弧(hu)(hu)(hu)(hu)(hu)作熱源。在(zai)形(xing)成接頭時(shi)，可以(yi)采用也可以(yi)不(bu)采用填充金屬。所用的電(dian)(dian)(dian)極是(shi)在(zai)焊(han)(han)(han)接過程中熔(rong)化(hua)的焊(han)(han)(han)絲(si)時(shi)，叫作熔(rong)化(hua)極電(dian)(dian)(dian)弧(hu)(hu)(hu)(hu)(hu)焊(han)(han)(han)，諸如手(shou)弧(hu)(hu)(hu)(hu)(hu)焊(han)(han)(han)、埋弧(hu)(hu)(hu)(hu)(hu)焊(han)(han)(han)、氣體保(bao)護(hu)(hu)電(dian)(dian)(dian)弧(hu)(hu)(hu)(hu)(hu)焊(han)(han)(han)、管(guan)狀焊(han)(han)(han)絲(si)電(dian)(dian)(dian)弧(hu)(hu)(hu)(hu)(hu)焊(han)(han)(han)等(deng)；所用的電(dian)(dian)(dian)極是(shi)在(zai)焊(han)(han)(han)接過程中不(bu)熔(rong)化(hua)的碳棒或(huo)鎢(wu)棒時(shi)，叫作不(bu)熔(rong)化(hua)極電(dian)(dian)(dian)弧(hu)(hu)(hu)(hu)(hu)焊(han)(han)(han)，諸如鎢(wu)極氬弧(hu)(hu)(hu)(hu)(hu)焊(han)(han)(han)、等(deng)離(li)子弧(hu)(hu)(hu)(hu)(hu)焊(han)(han)(han)等(deng)。

（2）埋弧焊

埋(mai)(mai)弧(hu)焊(han)(han)(han)(han)(han)(han)是以連續送時的(de)(de)(de)焊(han)(han)(han)(han)(han)(han)絲作為電(dian)極(ji)和填(tian)充金屬(shu)。焊(han)(han)(han)(han)(han)(han)接(jie)(jie)時，在(zai)焊(han)(han)(han)(han)(han)(han)接(jie)(jie)區(qu)的(de)(de)(de)上(shang)面(mian)(mian)覆蓋一(yi)(yi)層(ceng)顆(ke)粒狀焊(han)(han)(han)(han)(han)(han)劑(ji)，電(dian)弧(hu)在(zai)焊(han)(han)(han)(han)(han)(han)劑(ji)層(ceng)下燃燒，將焊(han)(han)(han)(han)(han)(han)絲端部和局部母(mu)材熔化(hua)(hua)，形成焊(han)(han)(han)(han)(han)(han)縫(feng)。在(zai)電(dian)弧(hu)熱的(de)(de)(de)作用(yong)(yong)(yong)下，上(shang)部分(fen)(fen)焊(han)(han)(han)(han)(han)(han)劑(ji)熔化(hua)(hua)熔渣并(bing)與液態金屬(shu)發生冶金反應。熔渣浮在(zai)金屬(shu)熔池(chi)的(de)(de)(de)表面(mian)(mian)，一(yi)(yi)方(fang)面(mian)(mian)可(ke)(ke)以保護焊(han)(han)(han)(han)(han)(han)縫(feng)金屬(shu)，防(fang)止(zhi)空(kong)氣的(de)(de)(de)污(wu)染(ran)，并(bing)與熔化(hua)(hua)金屬(shu)產生物理化(hua)(hua)學反應，改善(shan)焊(han)(han)(han)(han)(han)(han)縫(feng)金屬(shu)的(de)(de)(de)萬分(fen)(fen)及性能；另一(yi)(yi)方(fang)面(mian)(mian)還(huan)可(ke)(ke)以使焊(han)(han)(han)(han)(han)(han)縫(feng)金屬(shu)緩慢泠(ling)卻(que)。埋(mai)(mai)弧(hu)焊(han)(han)(han)(han)(han)(han)可(ke)(ke)以采(cai)用(yong)(yong)(yong)較大(da)的(de)(de)(de)焊(han)(han)(han)(han)(han)(han)接(jie)(jie)電(dian)流(liu)。與手弧(hu)焊(han)(han)(han)(han)(han)(han)相(xiang)比，其大(da)的(de)(de)(de)優(you)點是焊(han)(han)(han)(han)(han)(han)縫(feng)質(zhi)量好，焊(han)(han)(han)(han)(han)(han)接(jie)(jie)速(su)度高(gao)。因此，它特別(bie)適(shi)于(yu)焊(han)(han)(han)(han)(han)(han)接(jie)(jie)大(da)型工件的(de)(de)(de)直縫(feng)的(de)(de)(de)環縫(feng)。而且(qie)多數采(cai)用(yong)(yong)(yong)機械(xie)化(hua)(hua)焊(han)(han)(han)(han)(han)(han)接(jie)(jie)。埋(mai)(mai)弧(hu)焊(han)(han)(han)(han)(han)(han)已(yi)廣泛用(yong)(yong)(yong)于(yu)碳鋼、低(di)合金結構鋼和不銹鋼的(de)(de)(de)焊(han)(han)(han)(han)(han)(han)接(jie)(jie)。由于(yu)熔渣可(ke)(ke)降(jiang)低(di)接(jie)(jie)頭冷卻(que)速(su)度，故某些高(gao)強(qiang)度結構鋼、高(gao)碳鋼等(deng)也可(ke)(ke)采(cai)用(yong)(yong)(yong)埋(mai)(mai)弧(hu)焊(han)(han)(han)(han)(han)(han)焊(han)(han)(han)(han)(han)(han)接(jie)(jie)。
