焊接時聽到沙……沙的聲音，（小電流時聲音是滋滋聲）。焊接時焊機的電流表，電壓表的指針穩(wěn)定，擺動小。2.比較好規(guī)范的調(diào)整方法：根據(jù)焊件厚度，焊縫位置，選擇焊絲直徑，氣體流量，焊接電流。在試板上試焊，根據(jù)選擇的送絲速度，細心調(diào)整焊接電壓，比較好的浮動焊接電壓一般在1-2V之間。根據(jù)試板上焊縫成形情況，適當調(diào)整送絲速度，焊接電壓，達到比較好焊接規(guī)范。在工件上正式焊接過程中，應注意焊接回路，接觸電阻引起的電壓降，及時調(diào)整（微調(diào)）焊接電壓，確保焊接過程穩(wěn)定。3.焊接規(guī)范匹配不良的焊接現(xiàn)象及排除：當焊絲端頭始終有滴狀金屬小球存在，且過度頻率偏低，此情況說明焊接電壓偏高，此時應加快焊絲速度或降低焊接電壓。當焊絲干伸偏短時能正常焊接，稍長就出現(xiàn)頂絲現(xiàn)象，說明焊接電壓偏低，此時應通過降低送絲速度或升高焊接電壓。4、調(diào)試焊接參數(shù)時應注意以下幾點：先把送絲速度調(diào)低點，上海GGG70L焊條焊絲生產(chǎn)廠。再調(diào)焊接電壓，焊接電流應根據(jù)焊接母材的厚度來控制。再調(diào)送絲速度，這時把送絲調(diào)到正好（電弧能夠把焊絲溶解，且溶解的很舒服）。聽聲音，上海GGG70L焊條焊絲生產(chǎn)廠，看飛濺。如果溶解的很舒服，上海GGG70L焊條焊絲生產(chǎn)廠，聲音是很平穩(wěn)的，不會乒乓作響，飛濺也少。5、在保證焊縫熔透（這里不是焊穿的意思）的情況下。?用合金含量高于母材的焊絲作填充金屬，通?？煞乐购缚p金屬裂紋。上海GGG70L焊條焊絲生產(chǎn)廠</p><div

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，焊劑成份中若以酸性為主，焊接后便生成酸性焊渣，同樣的以堿性（石灰質(zhì)）焊劑為主將產(chǎn)生堿性焊渣。酸性系統(tǒng)的焊材焊接性非常好，焊接過程中電弧平順穩(wěn)定，形態(tài)類似射流弧，飛濺量少，作業(yè)上廣為焊接人員所喜歡，熔填金屬機械性普通但可達AWS規(guī)范的要求。焊劑為堿性系統(tǒng)的焊材可使熔填金屬獲得非常優(yōu)良的延性與韌性，但作業(yè)性遠較酸性系為差。熔滴的過渡多以球滴過渡為主，飛濺較多。低合金鋼焊材的焊劑系統(tǒng)的開發(fā)融合了酸性系的作業(yè)性與堿性系的優(yōu)良機械性。焊絲電火花類編輯電火花放電涂層冷焊機**焊絲，應用于在常溫狀態(tài)下進行堆焊或焊接時用，焊補一秒后特點是焊絲溫度不超過40攝氏度，持續(xù)焊不超高80攝氏度。主要用于一些不耐熱的零件修復，焊補時，溫度一般控制在40攝氏度左右，壁厚在，比較高不高于一百攝氏度。焊絲焊補時熱影響區(qū)非常小，不會產(chǎn)生內(nèi)應力。非常適合鑄造件缺點，零件表面拉傷、磨損，模具缺點的修復。焊絲溫度為什么這么低，因為該焊絲熔化時是微熔狀態(tài)，在與工件接觸時。</p><p> 藥芯焊絲焊接時比CO2實芯焊絲的飛濺要小得多，下圖為藥芯焊絲與CO2實芯焊絲飛濺大小的比較。焊接質(zhì)量好一般CO2實芯焊絲只適合于低碳鋼或強度級別較低的低合金鋼的焊接，而藥芯焊絲則適用于各種材料的焊接，不僅包括各種結(jié)構(gòu)鋼，也包括不銹鋼等特殊材料。藥芯焊絲焊縫的低溫沖擊韌度比實芯焊絲有了很大的提高，可適用于各種重要結(jié)構(gòu)的焊接，而CO2實芯焊絲一般只用于0度以上工作的一般鋼結(jié)構(gòu)。綜合焊接成本：低藥芯焊絲相對價格較高，但其綜合生產(chǎn)成本比焊條電弧焊要低許多，與CO2實芯焊絲大體相當。藥芯焊絲的型號及牌號按GB10045—88規(guī)怎定，藥芯焊絲***部分以英文字母“EF”表示藥芯焊絲代號，代號后面的***位數(shù)字表示主要適用的焊接位置：“0”表示用于平焊和橫焊，“1”表示用于全位置焊。代號后面的第二位數(shù)字或英文字母為分類代號。第二部分在短橫線后用四位數(shù)字表示焊縫金屬的力學性能。如焊絲型號EF03-5042。實際生產(chǎn)中還經(jīng)常用牌號來表示藥芯焊絲的類型。藥芯焊絲生產(chǎn)牌號用如下符號表示：首字母“Y”表示藥芯焊絲；第二位字母表示藥芯焊絲種類，***、第二位數(shù)字表示焊絲特點；第三位數(shù)字表示溶渣類型（或第三位以后之數(shù)字及元素符號表示焊縫金屬化學成分）。?焊絲的表面不涂防氧化作用的焊劑。</p><div

控制層間溫度對避免產(chǎn)生晶問腐蝕及熱裂紋尤為重要，并可控制焊縫根部的氧化，因此焊接時應盡量選用小線能量快速焊。層間溫度應控制在50~60℃。焊接工藝參數(shù)焊接前將坡口內(nèi)外邊緣10~20mm處焊件表面的油污、水、銹等清理干凈，露出金屬光澤。焊接工藝參數(shù)的選擇，見表4所示。2、焊縫外觀檢驗及性能試驗焊縫外觀成形良好，尤其是焊縫背面成形美觀，無焊瘤、未熔合、未焊透等缺點。射線檢測按照JB/T4730《承壓設(shè)備無損檢測》標準進行，II級及以上為合格，經(jīng)評定為合格。力學性能試驗按GB/T228和GB/T2653規(guī)定的試驗方法，對焊接接頭試樣進行了拉伸試驗和彎曲試驗，拉伸實驗結(jié)果如表5所示，彎曲試驗結(jié)果如表6所示。實驗結(jié)果為合格。3、焊接操作要領(lǐng)不銹鋼藥芯焊絲是利用焊絲中間的藥粉熔化后，在熔敷金屬背面和正面形成熔渣進行保護，所以根部焊接時與實芯焊絲焊接的操作方法、電弧擺動頻率、填絲量有較大區(qū)別。（1）在焊接過程中，焊要做圓弧形擺動,其目的是使鐵水和熔渣加速分離，便于觀察熔池，同時也可增加母材坡口兩側(cè)的熱輸入量，防止出現(xiàn)單邊未熔合。在填充焊絲時，應將焊絲送到熔池根部并向下輕壓一下，以保證根部熔透及根部內(nèi)成形。。?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。江蘇日亞焊條焊絲訂購</p><p

在角焊等遮蔽性差的地方是2~3mm,在開槽深的地方是5~6mm,噴嘴至工作的距離一般不超過15mm。4、為防止焊接氣孔之出現(xiàn),焊接部位如有鐵銹、油污等務必清理干凈。5、焊接電弧長度,焊接普通鋼時,以2~4mm為佳,而焊接不銹鋼時,以1~3mm為佳,過長則保護效果不好。6、對接打底時,為防止底層焊道的背面被氧化,背面也需要實施氣體保護。7、為使氬氣很好地保護焊接熔池,和便于施焊操作,鎢極中心線與焊接處工件一般應保持80~85°角,填充焊絲與工件表面夾角應盡可能地小,一般為10°左右。8、防風與換氣。有風的地方,務請采取擋網(wǎng)的措施,而在室內(nèi)則應采取適當?shù)膿Q氣措施。二、不銹鋼MIG焊要點及注意事項1、采用平特性焊接電源,直流時采用反極性(焊絲接正極)2、一般采用純氬氣(純度為)或Ar+2%O2,流量以20~25L/min為宜。3、電弧長度,不銹鋼的MIG焊接,一般都在噴射過渡的條件下來施焊,電壓要調(diào)整到弧長在4~6mm的程度。4、防風。MIG焊接容易受到風的影響,有時微風而產(chǎn)生氣孔,所以風速在。三、不銹鋼藥芯焊絲焊接要點及注意事項1、采用平特性焊接電源,直流焊接時采用反極性。使用一般的CO2焊機就可以施焊,但送絲輪的壓力請稍調(diào)松。2、保護氣體一般為二氧化碳氣體,氣體流量以20~25L/min較適宜。上海GGG70L焊條焊絲生產(chǎn)廠</p><p
