并能確保其加工精度，還可使焊區(qū)顏色與母材一致。C808鑄鐵常溫焊接焊絲中含有少量Al，對鑄鐵而言，它是強石墨化元素，有一定的防止在焊接熔合區(qū)產(chǎn)生白口組.織的作用。采用C808鑄鐵常溫焊接焊絲，不必在焊件待焊部位開出的坡口底部加焊藥，并能確保保證優(yōu)良焊接效果。C808鑄鐵常溫焊接比現(xiàn)有的其它各種鑄鐵常溫焊接的熔化焊技術(shù)具有更好的抗裂性、可加工性，并可確保其熔合區(qū)Hbmax＜220,且焊區(qū)顏色與母材相比趨于一致。C808鑄鐵常溫焊接焊絲使用工藝過程簡單，焊工易于掌握，在焊前不預(yù)熱，焊后不熱處理的前提下，焊后可直接上機械加工線進行切削加工，能節(jié)省材料費用和電能，提高生產(chǎn)效率。例如，采用C808鑄鐵常溫焊接焊絲對內(nèi)燃機鑄鐵件加工面缺點的修復，可進行小孔的焊接焊補及焊后加工，并能確保保修鑄件的加工精度和質(zhì)量，從而可使用戶獲得滿意的結(jié)果和明顯的經(jīng)濟效益。實施例：對柴油機機體加工面上的M6螺紋孔處進行焊接焊補修復,其材料為HT250，已完成全部機械加工(見圖1)，要求焊接焊補過程不破壞機體的形狀、位置、精度。采用C808鑄鐵常溫焊接焊絲焊接后，對螺紋孔的重新加工要求達到規(guī)定的技術(shù)要求，并要求消除焊接焊補痕跡。主要操作方法：（1）用φ10鉆頭鉆孔。</p><p> 焊接生產(chǎn)中大量采用焊條電弧焊。在工業(yè)發(fā)達國家，焊條的產(chǎn)量仍占焊材總產(chǎn)量的30%左右。在我國，這一比例為80%~90%左右。但從世界焊材發(fā)展的總趨勢看，隨著氣體保護焊工藝的***應(yīng)用和藥芯焊絲不斷崛起，手工焊條總的需求量會逐年下滑，今后的主要應(yīng)用對象是修配及某些特殊場合。在焊絲的生產(chǎn)上，埋弧焊焊絲在我國已經(jīng)應(yīng)用得非常***，埋弧焊用薄鋼帶也有應(yīng)用。近年來氣體保護焊和藥芯焊絲的應(yīng)用得到很大發(fā)展，使焊絲在消耗焊材中所占的比例日益增加，成為一種重要的焊接材料。焊絲的分類焊絲按其結(jié)構(gòu)可分為實芯焊絲和藥芯焊絲。實芯焊絲多為冷拔鋼絲；而藥芯焊絲則是由薄鋼帶縱向折迭并加入藥粉后，再行拉拔而成。實芯焊絲使用的歷史比較長，為目前主要使用的焊絲；藥絲焊絲的使用比起實芯焊絲來晚了許多，但由于其具有一系列優(yōu)點，在生產(chǎn)中應(yīng)用得越來越多。焊接用的焊絲按其保護方式又可分為兩大類：一類是焊接時焊絲只起填充金屬和導電的作用，施焊過程中要依靠焊劑保護或氣體保護，如埋弧焊、CO2氣體保護焊中使用的實芯焊絲和CO2氣體保護焊中使用的部分藥芯焊絲；另一類焊絲在焊接過程中不需要外加氣體或焊劑的保護。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。</p><div

2）焊絲端部應(yīng)始終處于氬氣保護之中，防止合金元素的氧化、燒損。為使熔渣盡快浮出，根據(jù)情況可用焊絲對高溫熔池進行適當攪拌，不宜依靠降低焊速來促使熔渣浮出。焊后在焊縫表面形成的熔渣薄而脆，高溫時極易自行脫落，故焊接時應(yīng)戴好防護眼鏡，防止灼傷眼睛。（3）要獲得美觀均勻的焊縫很大程度上取決于正確掌握熔池的溫度。當發(fā)現(xiàn)熔池增大出現(xiàn)下凹，說明熔池溫度過高，這時應(yīng)迅速減少焊與工件的夾角，并加快焊接速度。當熔池小焊縫窄而高時，說明熔池溫度低，這時應(yīng)增大焊與工件的夾角，減慢焊接速度，減少焊絲添加量。（4）1Cr18Ni9不銹鋼在450~800℃溫度區(qū)加熱，常發(fā)生沿晶界的腐蝕破壞，稱為晶間腐蝕。為防止打底層焊縫金屬產(chǎn)生晶間腐蝕，應(yīng)以快焊快冷為原則，盡量采用小的焊接熱輸入、快速焊、短弧焊、小幅擺動。（5）焊接時焊要等速移動，禁止抖動。焊絲與工件表面的夾角在25°左右，既可保證藥芯焊絲冶金反應(yīng)的充分性，又可避免填充金屬的過熱。鎢極端頭與熔池表面的距離應(yīng)保持在3mm左右，使操作者的視線寬廣，送絲方便，避免焊縫夾鎢。（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。江西H13焊條焊絲廠</p><p
