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，蘇州SM2R焊絲生產(chǎn)廠，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，蘇州SM2R焊絲生產(chǎn)廠。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。～～～～～～～～～～～～～～氬弧焊對(duì)人體有多大危害？一定要重視，蘇州SM2R焊絲生產(chǎn)廠！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。大多數(shù)焊絲屬于此類(lèi)，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。蘇州SM2R焊絲生產(chǎn)廠</p><div

注：1、直徑不大于、E5015、E5016和E5018型焊條及直徑不大于，可適用于立焊和仰焊。2、E4322型焊條適宜單道焊。焊條型號(hào)舉例如下：例14、焊條的選用（1）結(jié)構(gòu)鋼（低碳鋼、中碳鋼、普通低合金鋼）焊條的選用采用結(jié)構(gòu)鋼制造的焊接結(jié)構(gòu)，大多要求焊縫金屬與母材等強(qiáng)度，此時(shí)可按結(jié)構(gòu)鋼的強(qiáng)度選擇相應(yīng)強(qiáng)度等級(jí)的焊條。選擇時(shí)應(yīng)注意以下兩點(diǎn)：1）鋼材的強(qiáng)度等級(jí)是按屈服點(diǎn)劃分的，而結(jié)構(gòu)鋼焊條的強(qiáng)度等級(jí)系指其抗拉強(qiáng)度的比較低保證值，兩者是不一致的。通常應(yīng)選擇抗拉強(qiáng)度保證值與母材相同或稍高的焊條。2）焊縫強(qiáng)度不是比母材高出愈多愈好，而應(yīng)等于或稍高于母材。如果焊縫強(qiáng)度過(guò)高，往往使焊縫的塑性下降，反而有害。當(dāng)焊接接頭不要求焊縫與其等強(qiáng)度時(shí)，可選用抗拉強(qiáng)度較低的焊條。（2）合金結(jié)構(gòu)鋼焊條的選用合金結(jié)構(gòu)鋼焊接時(shí)，通常均不要求焊縫金屬的合金成分與該鋼種的合金成分相同或相近，而主要考慮等強(qiáng)度。但如果母材是耐熱鋼、耐腐蝕鋼時(shí)，從保證焊接接頭的耐熱、耐腐蝕性能出發(fā)，則要求焊縫金屬的主要合金成分與母材相同或相近。此時(shí)，應(yīng)根據(jù)母材的化學(xué)成分選用焊條。（3）根據(jù)母材抗裂性要求選用焊條母材成分中，如果含C或S、P等雜質(zhì)較高時(shí)，很容易在焊縫中形成裂紋。特種焊絲訂購(gòu)對(duì)各種鋼材的焊接，適應(yīng)性強(qiáng)
