7、為使氬氣很好地保護(hù)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(yīng)保持80~85°角,填充焊絲與工件表面夾角應(yīng)盡可能地小，一般為10°左右。8、防風(fēng)與換氣。有風(fēng)的地方，務(wù)請(qǐng)采取擋網(wǎng)的措施，而在室內(nèi)則應(yīng)采取適當(dāng)?shù)膿Q氣措施。二、不銹鋼MIG焊要點(diǎn)及注意事項(xiàng)1、采用平特性焊接電源，直流時(shí)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(zhǎng)度，不銹鋼的MIG焊接，一般都在噴射過(guò)渡的條件下來(lái)施焊，電壓要調(diào)整到弧長(zhǎng)在4~6mm的程度。4、防風(fēng)。MIG焊接容易受到風(fēng)的影響，有時(shí)微風(fēng)而產(chǎn)生氣孔，所以風(fēng)速在，都應(yīng)當(dāng)采取防風(fēng)措施。三、不銹鋼藥芯焊絲焊接要點(diǎn)及注意事項(xiàng)1、采用平特性焊接電源，直流焊接時(shí)采用反極性。使用一般的CO2焊機(jī)就可以施焊，但送絲輪的壓力請(qǐng)稍調(diào)松。2、保護(hù)氣體一般為二氧化碳?xì)怏w，氣體流量以20~25L/min較適宜。3、焊嘴與工件間的距離以15~25mm為宜。4、干伸長(zhǎng)度，一般的焊接電流為250A以下時(shí)約15mm，250A以上時(shí)約20~25mm較為合適，安徽鈷基焊絲價(jià)格?！珰寤『笇?duì)人體有多大危害？一定要重視！焊接技術(shù)氬弧焊的危害程度要比焊條電弧焊相對(duì)來(lái)說(shuō)要大，但是沒(méi)有大到讓人望而生畏的地步，安徽鈷基焊絲價(jià)格。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，安徽鈷基焊絲價(jià)格、合金結(jié)構(gòu)鋼焊絲、不銹鋼焊絲和有色金屬焊絲等。安徽鈷基焊絲價(jià)格</p><div

不銹鋼焊條可分為鉻不銹鋼焊條和鉻鎳不銹鋼焊條。鉻不銹鋼具有一定的耐蝕（氧化性酸、有機(jī)酸、氣蝕）耐熱和耐蝕性能。通常被選作電站、化工、石油等設(shè)備材料。但鉻不銹鋼一般情況下可焊性較差，應(yīng)注意焊接工藝、熱處理?xiàng)l件及選用合適的電焊條。鉻鎳不銹鋼焊條具有良好耐腐蝕性和抗氧化性，廣泛應(yīng)用于化工、化肥、石油、醫(yī)療機(jī)械制造。為防止由于加熱而產(chǎn)生晶間腐蝕，焊接電流不宜太大，比碳鋼焊條較少20%左右，電弧不宜過(guò)長(zhǎng)，層間快冷，以窄焊道為宜。不銹鋼焊接要點(diǎn)與注意事項(xiàng)一、采用垂直外特性的電源，直流時(shí)采用正極性(焊絲接負(fù)極)1、一般適合于6mm以下薄板的焊接，具有焊縫成型美觀，焊接變形量小的特點(diǎn)。2、保護(hù)氣體為氬氣，純度為。當(dāng)焊接電流為50~150A時(shí)，氬氣流量為8~10L/min，當(dāng)電流為150~250A時(shí)，氬氣流量為12~15L/min。3、鎢極從氣體噴嘴突出的長(zhǎng)度，以4~5mm為佳，在角焊等遮蔽性差的地方是2~3mm，在開(kāi)槽深的地方是5~6mm，噴嘴至工作的距離一般不超過(guò)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(wù)必清理干凈。5、焊接電弧長(zhǎng)度，焊接普通鋼時(shí)，以2~4mm為佳，而焊接不銹鋼時(shí)，以1~3mm為佳，過(guò)長(zhǎng)則保護(hù)效果不好。6、對(duì)接打底時(shí)。</p><p> 2、酸性焊條和堿性焊條焊條藥皮是由一定數(shù)量及用途的礦石、礦物、鐵合金、化工材料、有機(jī)物混合而成，其中大部分是金屬和非金屬氧化物。如果藥皮的成分以酸性氧化物為主（如氧化鈦、硅砂）的，稱為酸性焊條，生產(chǎn)中常用的是鈦鈣型焊條；如果藥皮的成分以堿性氧化物為主（如氧化鈣）的，稱為堿性焊條，生產(chǎn)中常用的是以碳酸鹽和螢石為主的低氫型焊條。酸性焊條和堿性焊條的操作性能比較，見(jiàn)表3-3。3、焊條的分類與型號(hào)表示（1）焊條的分類根據(jù)所焊材料的不同，焊條可分為低碳鋼及低合金鋼焊條、鉬和鉻鉬耐熱鋼焊條、不銹鋼焊條（包括奧氏體不銹鋼焊條和鉻不銹鋼焊條兩大類）、堆焊焊條、低溫鋼焊條、鑄鐵焊條、鎳和鎳合金焊條、銅和銅合金焊條以及鋁和鋁合金焊條九類。（2）結(jié)構(gòu)鋼焊條型號(hào)的編制方法根據(jù)GB5117-85“碳鋼焊條”、GB5118-85“低合金鋼焊條”的規(guī)定，焊條型號(hào)編制方法如下：字母E表示焊條；前兩位數(shù)字表示熔敷金屬抗拉強(qiáng)度的**小值；第三位數(shù)字表示焊條的焊接位臵，0及1表示焊條適用于全位臵焊接（平、立、仰、橫），2表示焊條適用于平焊及平角焊，4表示焊條適用于向下立焊；第三位和第四位數(shù)字組合時(shí)表示焊接電流種類及藥皮類型。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(yuǎn)較酸性系為差。</p><div

因接觸面很小，溫度急劇上升，在未熔化前，將焊條提起，產(chǎn)生電弧的引弧方法。此種方法易于掌握，但容易沾污坡口，影響焊接質(zhì)量。上述兩種引弧方法應(yīng)根據(jù)具體情況靈活應(yīng)用。擦劃法引弧雖比較容易，但這種方法使用不當(dāng)時(shí)，會(huì)擦傷焊件表面。為盡量減少焊件表面的損傷，應(yīng)在焊接坡口處擦劃，擦劃長(zhǎng)度以20～25mm為宜。在狹窄的地方焊接或焊件表面不允許有劃傷時(shí)，應(yīng)采用碰擊法引弧。碰擊法引弧較難掌握，焊條的提起動(dòng)作太快并且焊條提得過(guò)高，電弧易熄滅；動(dòng)作太慢，會(huì)使焊條粘在工件上。當(dāng)焊條一旦粘在工件上時(shí)，應(yīng)迅速將焊條左右擺動(dòng)，使之與焊件分離；若仍不能分離時(shí)，應(yīng)立即松開(kāi)焊鉗切斷電源，以免短路時(shí)間過(guò)長(zhǎng)而損壞電焊機(jī)。(3)引弧的技術(shù)要求。在引弧處，由于鋼板溫度較低，焊條藥皮還沒(méi)有充分發(fā)揮作用，會(huì)使引弧點(diǎn)處的焊縫較高，熔深較淺，易產(chǎn)生氣孔，所以通常應(yīng)在焊縫起始點(diǎn)后面10mm處引弧，如圖3—15。引燃電弧后拉長(zhǎng)電弧，并迅速將電弧移至焊縫起點(diǎn)進(jìn)行預(yù)熱。預(yù)熱后將電弧壓短，酸性焊條的弧長(zhǎng)約等于焊條直徑，堿性焊條的弧長(zhǎng)應(yīng)為焊條直徑的一半左右，進(jìn)行正常焊接。采用上述引弧方法即使在引弧處產(chǎn)生氣孔，也能在電弧第二次經(jīng)過(guò)時(shí)，將這部分金屬重新熔化。熔滴的過(guò)渡多以球滴過(guò)渡為主，飛濺較多。安徽SKD-11焊絲供貨廠</p><p
