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(xiàn)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，浙江SM2R焊絲供應(yīng)商。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，浙江SM2R焊絲供應(yīng)商，但送絲輪的壓力請(qǐng)稍調(diào)松。2，浙江SM2R焊絲供應(yīng)商、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。～～～～～～～～～～～～～～氬弧焊對(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。藥芯焊絲工藝性能好，焊縫成形美觀采用氣渣聯(lián)合保護(hù)，獲得良好成形。浙江SM2R焊絲供應(yīng)商</p><div
