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(wù)必清理干凈。5、焊接電弧長度,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,過長則保護(hù)效果不好。6、對(duì)接打底時(shí),為防止底層焊道的背面被氧化,背面也需要實(shí)施氣體保護(hù)。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(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。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，江蘇THW焊條焊絲生產(chǎn)廠,直流焊接時(shí)采用反極性，江蘇THW焊條焊絲生產(chǎn)廠。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，江蘇THW焊條焊絲生產(chǎn)廠。?熔滴的過渡多以球滴過渡為主，飛濺較多。江蘇THW焊條焊絲生產(chǎn)廠</p><div

藥芯焊絲的截面形狀多種多樣，下圖各種藥芯焊絲的截面形狀。藥芯焊絲**簡(jiǎn)單的截面形狀是“O”形，通常又稱為管狀焊絲。這種焊絲由于芯部粉劑不導(dǎo)電，電弧容易沿四周的鋼皮旋轉(zhuǎn)，使得電弧穩(wěn)定性差。因此“0”形只用于制造細(xì)徑藥芯焊絲。異形焊絲因鋼皮在整個(gè)截面上分布比較均勻，所以電弧燃燒穩(wěn)定，焊絲熔化均勻，冶金反應(yīng)進(jìn)行得比較充分，適合于制造直徑。藥芯焊絲的優(yōu)點(diǎn)生產(chǎn)效率高藥芯焊絲可進(jìn)行連續(xù)的自動(dòng)化和半自動(dòng)化生產(chǎn)，與焊條相比，**節(jié)約了更換焊條、引弧和收弧等輔助工序的時(shí)間。同時(shí)它的焊接飛濺小，不易堵塞焊嘴，所以比CO2實(shí)芯焊絲更適于機(jī)器人焊接。熔敷速度快，飛濺小：熔敷速度是指熔焊過程中，單位時(shí)間內(nèi)熔敷在焊件上的金屬量。藥芯焊絲之所以比焊條熔敷速度快，主要是因?yàn)樗梢允褂酶蟮暮附与娏鳎煌瑫r(shí)，藥芯焊絲中只含質(zhì)量分?jǐn)?shù)為15%~20%左右的藥粉，而焊條的涂料藥皮質(zhì)量分?jǐn)?shù)占25%以上，因此電能可以更有效地用來熔化焊絲的金屬部分。與CO2實(shí)芯焊絲相比，由于其電流集中于外表鋼皮，電流密度大，所產(chǎn)生的電阻熱更大；此外，飛濺小，所熔化金屬可以更有效地進(jìn)入熔池，因而藥芯焊絲甚至比CO2實(shí)芯焊絲的熔敷速度還要快。?焊絲包裝成卷或成桶以避免線材相互糾纏或折損。</p><div
