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，鈷基焊絲商家。焊條端部有一段沒有藥皮的夾持端，被焊鉗夾住后可以傳導電流（藥皮不導電），焊條末端的藥皮磨成錐形，便于焊接時引弧。焊條上端藥皮處印有該焊條的型號或牌號，以便焊工使用時識別。（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。常用牌號為H08A，含義如下：H08A焊芯的化學成分，見表3-1。碳在焊接過程中會引起飛濺，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。焊芯的長度與焊芯的直徑（即焊條的直徑）有關，見表3-2，鈷基焊絲商家。焊芯直徑越細，電阻越大，焊接時由于電流通過焊芯所產(chǎn)生的電阻熱也越大，鈷基焊絲商家，使藥皮發(fā)紅變質(zhì)，所以其長度就越短。生產(chǎn)中常用的焊芯直徑是，，。（2）藥皮在焊接過程中藥皮的作用是：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）通過熔渣與熔化金屬之間的化學反應，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性能。藥芯焊絲中的藥粉成分一般與焊條藥皮相似。鈷基焊絲商家</p><div

注：1、直徑不大于、E5015、E5016和E5018型焊條及直徑不大于，可適用于立焊和仰焊。2、E4322型焊條適宜單道焊。焊條型號舉例如下：例14、焊條的選用（1）結(jié)構(gòu)鋼（低碳鋼、中碳鋼、普通低合金鋼）焊條的選用采用結(jié)構(gòu)鋼制造的焊接結(jié)構(gòu)，大多要求焊縫金屬與母材等強度，此時可按結(jié)構(gòu)鋼的強度選擇相應強度等級的焊條。選擇時應注意以下兩點：1）鋼材的強度等級是按屈服點劃分的，而結(jié)構(gòu)鋼焊條的強度等級系指其抗拉強度的比較低保證值，兩者是不一致的。通常應選擇抗拉強度保證值與母材相同或稍高的焊條。2）焊縫強度不是比母材高出愈多愈好，而應等于或稍高于母材。如果焊縫強度過高，往往使焊縫的塑性下降，反而有害。當焊接接頭不要求焊縫與其等強度時，可選用抗拉強度較低的焊條。（2）合金結(jié)構(gòu)鋼焊條的選用合金結(jié)構(gòu)鋼焊接時，通常均不要求焊縫金屬的合金成分與該鋼種的合金成分相同或相近，而主要考慮等強度。但如果母材是耐熱鋼、耐腐蝕鋼時，從保證焊接接頭的耐熱、耐腐蝕性能出發(fā)，則要求焊縫金屬的主要合金成分與母材相同或相近。此時，應根據(jù)母材的化學成分選用焊條。（3）根據(jù)母材抗裂性要求選用焊條母材成分中，如果含C或S、P等雜質(zhì)較高時，很容易在焊縫中形成裂紋。模具焊絲批發(fā)?工藝性能好，焊縫成形美觀采用氣渣聯(lián)合保護，獲得良好成形。</p><div

分別是焊條的送進運動、焊條的橫向擺動運動和焊條的沿焊縫移動運動，詳見圖3—16。焊條的三個基本運動1—焊條送進2—焊條擺動3—沿焊縫移動(1)焊條的送進運動。主要是用來維持所要求的電弧長度。由于電弧的熱量熔化了焊條端部，電弧逐漸變長，有熄弧的傾向。要保持電弧繼續(xù)燃燒，必須將焊條向熔池送進，直至整根焊條焊完為止。為保證一定的電弧長度，焊條的送進速度應與焊條的熔化速度相等，否則會引起電弧長度的變化，影響焊縫的熔寬和熔深。(2)焊條的擺動和沿焊縫移動。這兩個動作是緊密相聯(lián)的，而且變化較多、較難掌握。通過兩者的聯(lián)合動作可獲得一定寬度、高度和一定熔深的焊縫。所謂焊接速度即單位時間內(nèi)完成的焊縫長度。如圖3—17，表示焊接速度對焊縫成形的影響。焊接速度太慢，會焊成寬而局部隆起的焊縫；太快，會焊成斷續(xù)細長的焊縫；焊接速度適中時，才能焊成表面平整，焊波細致而均勻的焊縫。焊接速度對焊縫成形的影響(3)運條手法。為了控制熔池溫度，使焊縫具有一定的寬度和高度，在生產(chǎn)中經(jīng)常采用下面幾種運條手法。1)直線形運條法。采用直線形運條法焊接時，應保持一定的弧長，焊條不擺動并沿焊接方向移動。由于此時焊條不作橫向擺動，所以熔深較大。非常適合鑄造件缺點，零件表面拉傷、磨損，模具缺點的修復。</p><div

紅外線輻射約為普通焊條電弧焊的1～，氬弧焊電弧產(chǎn)生的紫外線輻射約為焊條電弧焊的5～20倍。在有限空間內(nèi)焊接時，臭氧的濃度可增大到危險程度，在焊接過程中，還會產(chǎn)生二氧化碳，一氧化碳等有害氣體和金屬粉塵，這些都對焊工產(chǎn)生一定的危害。所以我們在焊接過程中要做好防護，選用電極的材料，要盡量選用放射性小的鈰鎢。磨削電極時，要戴好口罩，手套，且工作后要洗手，讓危害降到比較低。高頻電磁場的危害焊接通常使用高頻振蕩器的頻率為200～500kHz，電壓2500～3500V，電場強度140～190V/m。引弧時，產(chǎn)生的高頻電磁場強度在60～110V/m之間，超過參考衛(wèi)生標準(20V/m)數(shù)倍。在非熔化極氬弧焊和等離子弧焊割時，常用高頻振蕩器來激發(fā)引弧，有的交流氬弧焊機還用高頻振蕩器來穩(wěn)定電弧。人體在高頻電磁場作用下，能吸收一定的輻射能量，產(chǎn)生生物學效應，主要是熱作用。高頻電磁場強度受許多因素影響，如距離，振蕩器和振蕩回路越近場強越高，反之則越低。此外，與高頻部分的屏蔽程度等有關。人體在高頻電磁場作用下會產(chǎn)生生物學效應，焊工長期接觸高頻電磁場能引起植物神經(jīng)功能紊亂和神經(jīng)衰弱。表現(xiàn)為全身不適、頭昏***、疲乏、食欲不振、***及血壓偏低等癥狀。制造/生產(chǎn)過程中如何不使焊絲內(nèi)因管制不良而造成部分線材形成中空（沒有焊劑）是藥芯焊絲生產(chǎn)品質(zhì)的關鍵。模具焊絲批發(fā)</p><p
