躺焊(han)(han)(han)(han)(han)是一種(zhong)(zhong)將(jiang)焊(han)(han)(han)(han)(han)條靜(jing)止地放置在(zai)(zai)焊(han)(han)(han)(han)(han)道(dao)上進(jin)行焊(han)(han)(han)(han)(han)接(jie)(jie)的(de)焊(han)(han)(han)(han)(han)條電弧焊(han)(han)(han)(han)(han)。焊(han)(han)(han)(han)(han)接(jie)(jie)時，電弧在(zai)(zai)焊(han)(han)(han)(han)(han)條長度(du)方(fang)向上行走，不(bu)斷將(jiang)躺在(zai)(zai)焊(han)(han)(han)(han)(han)道(dao)上的(de)焊(han)(han)(han)(han)(han)條熔化。這種(zhong)(zhong)方(fang)法是20世(shi)紀30年代由奧(ao)地利Elin公司(si)的(de)George Hafergut開發(fa)的(de)，因(yin)此(ci)被稱為(wei)Elin-Hafergut焊(han)(han)(han)(han)(han)（美(mei)國(guo)號為(wei)2269369）。這種(zhong)(zhong)方(fang)法也是一種(zhong)(zhong)自動化方(fang)法，因(yin)為(wei)電弧引燃(ran)起來后，就(jiu)不(bu)需要焊(han)(han)(han)(han)(han)工(gong)(gong)進(jin)行操作。這種(zhong)(zhong)方(fang)法可用(yong)于0.03~0.12in（0.8~3mm）厚(hou)工(gong)(gong)件的(de)I形(xing)坡口對接(jie)(jie)焊(han)(han)(han)(han)(han)、0.03~0.120in（0.8~3mm）厚(hou)工(gong)(gong)件的(de)搭接(jie)(jie)角焊(han)(han)(han)(han)(han)縫以(yi)及(ji)板(ban)厚(hou)在(zai)(zai)3/16in（5mm）以(yi)上的(de)角焊(han)(han)(han)(han)(han)縫。通常采用(yong)E6024及(ji)E7028焊(han)(han)(han)(han)(han)條。

電阻焊變壓器的性(xing)能特(te)點總結起來(lai)可以分(fen)為以下三大特(te)點：

一、功率(lv)大但是可調節

因(yin)(yin)焊(han)接電(dian)流(liu)大(da)，故電(dian)阻焊(han)變(bian)(bian)(bian)壓器容量皆大(da)于(yu)50kVA，由于(yu)變(bian)(bian)(bian)壓器繞(rao)組僅一(yi)匝或兩匝，因(yin)(yin)此只(zhi)能改變(bian)(bian)(bian)一(yi)次繞(rao)組匝數，以(yi)改變(bian)(bian)(bian)焊(han)接功(gong)率。

二(er)、初級電(dian)壓高，其次級電(dian)壓很低而電(dian)流(liu)很大

電(dian)(dian)阻(zu)焊(han)(han)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)不同于(yu)弧焊(han)(han)機變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)，而接近于(yu)低(di)壓(ya)(ya)(ya)(ya)大(da)電(dian)(dian)流(liu)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)，是隔離變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)的一種特殊形式，煙臺(tai)焊(han)(han)工(gong)培訓，公(gong)單(dan)相(xiang)交(jiao)流(liu)與三相(xiang)整流(liu)兩大(da)系列，電(dian)(dian)工(gong)焊(han)(han)工(gong)安全培訓，所(suo)有電(dian)(dian)阻(zu)焊(han)(han)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)的特征(zheng)是初級(ji)電(dian)(dian)壓(ya)(ya)(ya)(ya)高，焊(han)(han)工(gong)電(dian)(dian)工(gong)培訓費用，其(qi)次級(ji)電(dian)(dian)壓(ya)(ya)(ya)(ya)很低(di)而電(dian)(dian)流(liu)很大(da)。

電弧(hu)焊(han)(han)技(ji)(ji)術(shu)(shu)主要包(bao)括：手弧(hu)焊(han)(han)技(ji)(ji)術(shu)(shu)、埋(mai)弧(hu)焊(han)(han)技(ji)(ji)術(shu)(shu)、鎢(wu)極氣(qi)體保(bao)護電弧(hu)焊(han)(han)技(ji)(ji)術(shu)(shu)、等離子弧(hu)焊(han)(han)技(ji)(ji)術(shu)(shu)、熔化極氣(qi)體保(bao)護電弧(hu)焊(han)(han)技(ji)(ji)術(shu)(shu)、管狀焊(han)(han)絲電弧(hu)焊(han)(han)技(ji)(ji)術(shu)(shu)。電阻焊(han)(han)主要是以電阻熱(re)(re)為(wei)(wei)能(neng)源的(de)(de)一類焊(han)(han)接方法(fa)，包(bao)括以熔渣(zha)電阻熱(re)(re)為(wei)(wei)能(neng)源的(de)(de)電渣(zha)焊(han)(han)和(he)以固體電阻熱(re)(re)為(wei)(wei)能(neng)源的(de)(de)電阻焊(han)(han)。怎么學(xue)好(hao)電焊(han)(han)技(ji)(ji)術(shu)(shu)? 如果從頭開始的(de)(de)話(hua)首先可以到(dao)國(guo)強電焊(han)(han)工(gong)培訓機(ji)構，電工(gong)電焊(han)(han)工(gong)培訓班(ban)，期(qi)間認(ren)識相(xiang)關技(ji)(ji)師(shi)，有一定(ding)基礎之后開始尋求練習(xi)，然后選(xuan)擇一個技(ji)(ji)術(shu)(shu)型(xing)的(de)(de)作為(wei)(wei)良師(shi)益(yi)友。找(zhao)到(dao)良師(shi)益(yi)友后堅持操(cao)作實踐(jian)，開始采用請(qing)教方式排難解(jie)惑，慢慢演變成探討共進，堅持下來你也可以成為(wei)(wei)老師(shi)。
