在江(jiang)西(xi)氬(ya)弧(hu)焊中高頻高壓(ya)(ya)或脈沖引弧(hu)時(shi)，鎢電(dian)極與工件留2-5mm間隙，2000-3000V高壓(ya)(ya)擊穿空間形成(cheng)放電(dian)，強電(dian)場作(zuo)用(yong)下(xia)(xia)完成(cheng)引弧(hu)，后續(xu)低電(dian)壓(ya)(ya)維持電(dian)弧(hu)，使(shi)用(yong)高頻或脈沖電(dian)壓(ya)(ya)的焊機(ji)為江(jiang)西(xi)高壓(ya)(ya)焊機(ji)。江(jiang)西(xi)高壓(ya)(ya)焊工證需考核(he)獲得，技術(shu)不(bu)足可深造，技術(shu)強可考操作(zuo)證或等級證。接下(xia)(xia)來，江(jiang)西(xi)樂大教育網老師來為大家全(quan)方面介紹一下(xia)(xia)。

一(yi)、江西什(shen)么是高(gao)壓(ya)焊(han)工證（高(gao)壓(ya)焊(han)接原理及高(gao)壓(ya)焊(han)機）

在(zai)江西氬弧(hu)(hu)(hu)(hu)焊領域(yu)，引(yin)(yin)(yin)(yin)弧(hu)(hu)(hu)(hu)方式(shi)主要有(you)高(gao)(gao)(gao)頻(pin)(pin)高(gao)(gao)(gao)壓(ya)(ya)(ya)引(yin)(yin)(yin)(yin)弧(hu)(hu)(hu)(hu)法(fa)與脈沖引(yin)(yin)(yin)(yin)弧(hu)(hu)(hu)(hu)法(fa)。進行這兩種(zhong)引(yin)(yin)(yin)(yin)弧(hu)(hu)(hu)(hu)操作(zuo)(zuo)時，鎢電(dian)(dian)(dian)(dian)極(ji)會(hui)靠(kao)近(jin)工件卻不接(jie)觸，二者之(zhi)間保留2至5毫米的間隙(xi)。其(qi)引(yin)(yin)(yin)(yin)弧(hu)(hu)(hu)(hu)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)頗高(gao)(gao)(gao)，處于2000至3000V的范圍(wei)。引(yin)(yin)(yin)(yin)弧(hu)(hu)(hu)(hu)之(zhi)際，憑借高(gao)(gao)(gao)壓(ya)(ya)(ya)來擊穿電(dian)(dian)(dian)(dian)極(ji)和工件間的空(kong)間，從而產生火(huo)花放(fang)電(dian)(dian)(dian)(dian)現象(xiang)。在(zai)高(gao)(gao)(gao)壓(ya)(ya)(ya)環境下，電(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)(hu)空(kong)間會(hui)形成強電(dian)(dian)(dian)(dian)場，強化了陰極(ji)發(fa)射電(dian)(dian)(dian)(dian)子以(yi)及電(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)(hu)空(kong)間的電(dian)(dian)(dian)(dian)離作(zuo)(zuo)用，致(zhi)使電(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)(hu)空(kong)間由火(huo)花放(fang)電(dian)(dian)(dian)(dian)或(huo)(huo)輝光放(fang)電(dian)(dian)(dian)(dian)狀態轉(zhuan)變(bian)為電(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)(hu)放(fang)電(dian)(dian)(dian)(dian)。由于電(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)(hu)產生高(gao)(gao)(gao)溫，后續(xu)電(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)(hu)能維持(chi)在(zai)低電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)狀態，如(ru)此(ci)便完成了引(yin)(yin)(yin)(yin)弧(hu)(hu)(hu)(hu)流程。鑒于引(yin)(yin)(yin)(yin)弧(hu)(hu)(hu)(hu)時需(xu)高(gao)(gao)(gao)壓(ya)(ya)(ya)擊穿電(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)(hu)空(kong)間，出于安全考量，會(hui)運用高(gao)(gao)(gao)頻(pin)(pin)或(huo)(huo)脈沖電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)，這種(zhong)焊機即(ji)為江西高(gao)(gao)(gao)壓(ya)(ya)(ya)焊機。

二、江西什么(me)是(shi)高(gao)壓焊(han)工證（獲取方式及相關(guan)建議）

1、江(jiang)西高壓焊工(gong)證(zheng)必須通過相關考核才能獲取。

2、倘若個人技術尚未達標，建(jian)議前往江西專(zhuan)業學校進一步深造(zao)學習，提升技能水平。

3、若技術精(jing)湛過硬，則可以考取江西(xi)操作證或者等級證，以證明自身能力。
