1.概述背面自保護藥皮氬弧焊焊絲是一種特殊的涂層焊絲，焊接時保護藥皮會滲透到熔池背面，由于焊絲藥皮的凝固點比母材高，形成一層致密的保護層，使背面鐵液不被氧化。冷卻后這層渣殼會自動脫落，用壓縮空氣或水沖的方式極易***。這種焊絲的使用方法與普通氬弧焊焊絲相同，涂層不會影響正面的電弧和溶池形態(tài)。目前，已成功應(yīng)用于石油化工、電力建設(shè)等行業(yè)的不銹鋼管道焊接。2.背面自保護涂層焊絲的特點背面自保護藥皮氬弧焊焊絲的優(yōu)缺點：①背面藥皮剝脫性好，背面成形好。②適合全位置焊接。③焊接質(zhì)量優(yōu)良。④焊道耐腐蝕性強。⑤焊接速度較慢，焊縫和熱影響區(qū)易過熱。背面自保護涂層氬弧焊焊絲不受管材規(guī)格、焊接位置等因素的限制，操作靈活，并且減少了充氬時的準備工作。但由于焊絲表面有較薄的涂層，對焊工的操作水平要求較高，一些焊工往往不適應(yīng)該焊絲的焊接操作方法，焊縫背面容易出現(xiàn)內(nèi)凹、咬邊、夾渣及未焊透等焊接缺點。國產(chǎn)背面自保護涂層氬弧焊焊絲的涂層厚度比進口的稍厚，焊工在焊接時更易出現(xiàn)上述焊接缺點。筆者通過國產(chǎn)和進口涂層焊絲對比分析發(fā)現(xiàn)：國產(chǎn)的涂層焊絲在焊接工藝上不比進口的差，關(guān)鍵還是要掌握適當?shù)暮附硬僮骷记?。同樣?/p><p> 4）可用較大焊接電流進行全位置焊接。⑵缺點1）焊絲制造過程復(fù)雜2）焊接時，送絲較實心焊絲困難3）焊絲外表容易銹蝕，粉劑易吸潮，因此對藥芯焊絲保存一管理的要求更為嚴格焊絲焊劑功能編輯與被覆焊條相同，藥芯焊絲的制造商對焊劑成份均為其特有的配方，隨著焊材適用的功能不同，焊劑成份組成亦各不同。焊劑成份的基本功能略述如下：⑴除氧劑與除氮劑由于氮與氧可使焊道金屬造成氣孔或脆化，焊劑中必須添加錳與硅等除氧劑，至于自保護藥芯焊絲，焊劑中另需添加AL為除氮劑。以上添加除氧劑及除氮劑目的均在于凈化熔填金屬。⑵焊渣形成劑鈣、鉀、鈉或硅等均為焊渣形成劑，添加在焊劑中可以有效保護熔池不受大氣污染，焊渣可使焊道具較佳的外觀而且快速冷卻后又可以支撐全姿勢焊接時的熔池。焊渣的覆蓋更可緩和熔填金屬冷卻速率，此功能對低合金鋼的焊接尤其重要。⑶電弧穩(wěn)定劑鈉及鉀可以使電弧保持柔和順暢而且降低飛濺。⑷合金元素鉬、鉻、碳、錳、鎳及釩等合金元素的添加，可以提高（改善）熔填金屬的強度、延性、硬度及韌性等。⑸氣體形成劑氟石、石灰石等需添加在自保護藥芯焊絲中使燃燒產(chǎn)生保護氣體。⒊2焊渣的類別焊劑的成份決定焊材的焊接作業(yè)性與熔填金屬的機械性。在焊接結(jié)構(gòu)剛性大、接頭應(yīng)力高、焊縫易產(chǎn)生裂紋的不利情況下，應(yīng)考慮選用比母材強度低的焊條。</p><div

6）為避免在接頭收弧時產(chǎn)生縮孔，應(yīng)盡量采用短弧焊，焊擺動要均勻，要保證藥芯焊絲的焊接冶金反應(yīng)過程和脫渣過程充分進行，焊接速度應(yīng)與送絲頻率成正比。收弧時不要向前移動太遠，應(yīng)斜向前收弧，避免產(chǎn)生弧抗。4、結(jié)束語,根部焊道采用藥芯焊絲手工鎢極氬弧焊時，不僅改善了背面成形，提高了焊接質(zhì)量，而且節(jié)約了氬氣和大量輔助用工，降低了成本，提高了生產(chǎn)效率，從而可替代以往的手工鎢極氬弧焊填充實芯焊絲背面充氬保護的焊接方法。特別是焊接固定管口、死口連頭等背面充氬保護困難的位置時，其優(yōu)越性能更為***。采用藥芯焊絲工藝性能好，焊接工藝操作簡便，電弧穩(wěn)定、飛濺小、脫渣容易、焊縫成形美觀，其熔敷金屬力學性能達到了相關(guān)標準的規(guī)定。此工藝方法可應(yīng)用于其它奧氏體不銹鋼管子的打底層及蓋面層的焊接，值得在火力發(fā)電廠安裝工程中推廣應(yīng)用。用于焊接的**鋼絲可分為碳素結(jié)構(gòu)鋼、合金結(jié)構(gòu)鋼、不銹鋼三類。安徽小池酸素焊條</p><p

焊絲是作為填充金屬或同時作為導(dǎo)電用的金屬絲焊接材料。在氣焊和鎢極氣體保護電弧焊時，焊絲用作填充金屬；在埋弧焊、電渣焊和其他熔化極氣體保護電弧焊時，焊絲既是填充金屬，同時焊絲也是導(dǎo)電電極。焊絲的表面不涂防氧化作用的焊劑。中文名焊絲外文名Wire抗拉強度760N/mm2廷伸率26%形狀卷成圓形或異形特性焊接過程中有異味目錄1分類?軋制類?鑄造類?藥芯類?介紹?特點2焊劑功能3電火花類4CO2焊5型號6存放焊絲分類編輯焊絲軋制類大多數(shù)焊絲屬于此類，包括碳鋼焊絲、低合金結(jié)構(gòu)鋼焊絲、合金結(jié)構(gòu)鋼焊絲、不銹鋼焊絲和有色金屬焊絲等[1]。常見焊絲：SKD11>～HRC56～58焊補冷作鋼、五金沖壓模、切模、刀.具、成型模、工件硬面制作具高硬度、耐磨性及高韌性之氬焊條，焊補前先加溫預(yù)熱，否則易產(chǎn)生龜裂現(xiàn)象。63度刀口刃口焊絲>～HRC63～55，主要應(yīng)用于焊拉刀模，熱作高硬度具模，熱鍛總模，熱沖模，螺絲模，耐磨耗硬面，高速鋼，刀口修復(fù)。SKD61>?！獺RC40～43焊補鋅、鋁壓鑄模、具良好之耐熱性與耐龜裂性、熱氣沖模、鋁銅熱鍛模、鋁銅壓鑄模、具良好耐熱、耐磨、耐龜裂性。一般熱壓鑄模常有龜甲裂紋狀，大部分是由熱應(yīng)力所引起。安徽小池酸素焊條</p><p
