焊條介紹及1、焊芯及藥皮涂有藥皮的供手弧焊用的熔化電極，叫做焊條。焊條由藥皮和焊芯兩大部分所組成。焊條端部有一段沒(méi)有藥皮的夾持端，被焊鉗夾住后可以傳導(dǎo)電流（藥皮不導(dǎo)電），焊條末端的藥皮磨成錐形，便于焊接時(shí)引弧。焊條上端藥皮處印有該焊條的型號(hào)或牌號(hào)，以便焊工使用時(shí)識(shí)別。（1）焊芯碳素結(jié)構(gòu)鋼和低合金結(jié)構(gòu)鋼焊接用的焊條，其焊芯材料為低碳鋼。常用牌號(hào)為H08A，含義如下：H08A焊芯的化學(xué)成分，見表3-1。碳在焊接過(guò)程中會(huì)引起飛濺，并使焊縫產(chǎn)生氣孔和裂紋，所以必須限制焊芯中碳的含量。焊芯的長(zhǎng)度與焊芯的直徑（即焊條的直徑）有關(guān)，見表3-2。焊芯直徑越細(xì)，電阻越大，焊接時(shí)由于電流通過(guò)焊芯所產(chǎn)生的電阻熱也越大，使藥皮發(fā)紅變質(zhì)，所以其長(zhǎng)度就越短。生產(chǎn)中常用的焊芯直徑是，，。（2）藥皮在焊接過(guò)程中藥皮的作用是：1）使電弧穩(wěn)定燃燒。2）產(chǎn)生熔渣和氣體，防止空氣中的氧、氮侵入焊縫金屬，以提高焊縫質(zhì)量。3）產(chǎn)生的熔渣覆蓋在焊縫上，使焊縫表面成形良好。4）通過(guò)熔渣與熔化金屬之間的化學(xué)反應(yīng)，能增加焊縫金屬中合金元素的含量，改善和提高焊縫金屬的力學(xué)性能。</p><p>

因?yàn)楹笇娱g熔渣清理不徹底，又由于焊速快，熔池凝固較快，熔渣來(lái)不及浮出熔池而形成夾渣。解決夾渣時(shí)應(yīng)注意兩點(diǎn)：一是徹底***層間熔渣，特別是封底層與坡口兩側(cè)的夾渣較難***，要用尖頭小錘及鋼鋸條認(rèn)真清理；二是填充層施焊運(yùn)條時(shí)應(yīng)在坡口兩側(cè)停留的時(shí)間稍長(zhǎng)些，不僅能使熔渣有充足的時(shí)間浮出，還可使焊縫焊得平整，為蓋面層的焊接打好基礎(chǔ)。咬邊咬邊是蓋面層焊接時(shí)**難克服的缺點(diǎn)，產(chǎn)生的原因是咬邊處液態(tài)金屬重力較大，造成下垂所致。為了防止產(chǎn)生咬邊，要做到以下3點(diǎn)：一是蓋面層要薄，不宜超過(guò)2～3mm；二是運(yùn)條時(shí)擺動(dòng)要均勻，在坡口的兩側(cè)一定要壓低電弧，使邊緣部位熔化控制在1mm左右；三是選用合適的焊接電流，當(dāng)選用ф，焊接電流為110A，以避免因熱輸入偏大而造成的咬邊缺點(diǎn)。存取及搬運(yùn)焊絲時(shí)小心不要弄破包裝，特別是內(nèi)包裝“熱收縮膜”。上海H13焊絲銷售</p><p
