href="http://www.caoepaperfe.cn"><span style="font-size:36px;">中頻彎管特點(diǎn)</span></a></h3> <p align="left"> <span style="font-size:20px;">1.中頻彎管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）</span></p> <p align="left"> <span style="font-size:20px;">2.<a href="http://www.caoepaperfe.cn">中頻彎管</a>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)</span></p> <p align="left"> <span style="font-size:20px;">3.保護(hù)氣體為氬氣，純度為99.99%。當(dāng)焊接電流為50~50A時(shí)，氬氣流量為8~0L/min，當(dāng)電流為50~250A時(shí)，氬氣流量為2~5L/min。</span></p> <p align="left"> <span style="font-size:20px;">4.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~3mm為佳，過(guò)長(zhǎng)則保護(hù)效果不好。</span></p> <p align="left"> <span style="font-size:20px;">5.中頻彎管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。</span></p> <p align="left"> <span style="font-size: 20px;">6.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)5mm。</span></p> <p align="left"> <span style="font-size:20px;">7.<a href="http://www.caoepaperfe.cn">中頻彎管</a>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)。</span></p> <p align="left"> <span style="font-size:20px;">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。</span></p> <p align="left"> <span style="font-size:20px;">9.中頻彎管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0°左右。</span></p> <p> <span style="font-size:20px;">表面夾角應(yīng)盡可能地小，一般為0°左右。</span></p> <div id="l6r90vb" class="float_c news-page fs_14"> <div id="wyiscba" class="f_l"> 上一篇：<a href='/gsxw/1820.html'>什么是三通</a> </div> <div
