要做到以下要求：一是為了保證試板坡口兩側(cè)有良好的熔合，采用的焊接電流宜稍大，當(dāng)用ф，昆山NH45R焊絲價(jià)格，昆山NH45R焊絲價(jià)格，焊接電流以90A為宜；二是要采用短弧施焊，以利于保護(hù)熔池，同時(shí)利用電弧作用力把熔池鐵液托住，并且把部分熔滴過渡到試件背面（即上面）；三要使后續(xù)熔池覆蓋前一熔池的1/2，并適當(dāng)提高焊接速度，以減小熔深，減小液態(tài)金屬自身重力，避免焊縫金屬下垂上凹；四是保持正確的運(yùn)條方式，使焊條與試板左右兩側(cè)呈90o，并與焊接方向呈70o～80o的夾角。施焊時(shí)，焊件背面應(yīng)保持2/3弧柱，以利于熔滴過渡和熔池保護(hù)。運(yùn)條時(shí)應(yīng)左右輕微擺動(dòng)。當(dāng)焊至接近試板中部時(shí)，因變形使間隙變窄，此時(shí)可不使焊條左右橫向擺動(dòng)，而沿焊接方向連弧焊接；五是更換焊條接頭要迅速，應(yīng)在接頭部位處于紅熱狀態(tài)下迅速引弧，盡快恢復(fù)焊接狀態(tài)，這樣可使接頭處成形良好，昆山NH45R焊絲價(jià)格，也可減少氣孔、夾渣等缺點(diǎn)。填充層的焊接填充層采用左右擺動(dòng)運(yùn)條方式連弧焊接，操作昱應(yīng)注意兩點(diǎn)：一要使焊條與試板在左右方向上處于垂直狀態(tài)，以避免填充層焊縫左右不等厚，影響焊縫成形。為了把握好角度，有的焊工改用雙手握焊鉗施焊，效果不錯(cuò)；二要將道間熔渣清理干凈，避免出現(xiàn)夾渣。填充層以2層為宜，較薄的焊層。非常適合鑄造件缺點(diǎn)，零件表面拉傷、磨損，模具缺點(diǎn)的修復(fù)。昆山NH45R焊絲價(jià)格</p><div

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(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。浙江GZ60S焊絲若外觀顏色匹配是重要指標(biāo)時(shí)，選擇焊絲時(shí)必須考慮所形成焊縫組.織的成分及組.織。</p><div

分別是焊條的送進(jìn)運(yùn)動(dòng)、焊條的橫向擺動(dòng)運(yùn)動(dòng)和焊條的沿焊縫移動(dòng)運(yùn)動(dòng)，詳見圖3—16。焊條的三個(gè)基本運(yùn)動(dòng)1—焊條送進(jìn)2—焊條擺動(dòng)3—沿焊縫移動(dòng)(1)焊條的送進(jìn)運(yùn)動(dòng)。主要是用來維持所要求的電弧長(zhǎng)度。由于電弧的熱量熔化了焊條端部，電弧逐漸變長(zhǎng)，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(jìn)，直至整根焊條焊完為止。為保證一定的電弧長(zhǎng)度，焊條的送進(jìn)速度應(yīng)與焊條的熔化速度相等，否則會(huì)引起電弧長(zhǎng)度的變化，影響焊縫的熔寬和熔深。(2)焊條的擺動(dòng)和沿焊縫移動(dòng)。這兩個(gè)動(dòng)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(dòng)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(shí)間內(nèi)完成的焊縫長(zhǎng)度。如圖3—17，表示焊接速度對(duì)焊縫成形的影響。焊接速度太慢，會(huì)焊成寬而局部隆起的焊縫；太快，會(huì)焊成斷續(xù)細(xì)長(zhǎng)的焊縫；焊接速度適中時(shí)，才能焊成表面平整，焊波細(xì)致而均勻的焊縫。焊接速度對(duì)焊縫成形的影響(3)運(yùn)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(yùn)條手法。1)直線形運(yùn)條法。采用直線形運(yùn)條法焊接時(shí)，應(yīng)保持一定的弧長(zhǎng)，焊條不擺動(dòng)并沿焊接方向移動(dòng)。由于此時(shí)焊條不作橫向擺動(dòng)，所以熔深較大。</p><p>
