style="text-indent:25px">陶瓷襯墊橫焊縫怎么焊：橫焊是焊接垂直或傾斜平面上水平方向的焊縫。應(yīng)采用短弧焊接，并選用較小直徑焊接電流，以及適當(dāng)?shù)倪\(yùn)條方法。不開(kāi)坡口的對(duì)接橫焊，當(dāng)板厚為3-5毫米時(shí)應(yīng)采用雙面焊。正面焊時(shí)焊條直徑為3。2-4毫米，焊條與下板成75-80度。當(dāng)焊件較薄時(shí)，用直線往返形運(yùn)條法，使熔池金屬有機(jī)會(huì)冷卻，不至于使熔池溫度過(guò)高，可以防止燒穿。焊件較厚時(shí)，可采用短弧直線形或小斜圓圈形運(yùn)條法焊接，便可得到合適的熔深，運(yùn)條速度應(yīng)稍快些，旦要均勻，避免焊條熔化金屬過(guò)多地聚集在某一點(diǎn)上形成焊瘤和焊縫上部咬邊等缺陷。開(kāi)坡口的對(duì)接橫焊，靠前道焊縫選用細(xì)焊條，當(dāng)間隙大時(shí)宜采用直線往復(fù)形運(yùn)條法。第二道焊縫采用斜圓圈運(yùn)條法。在施焊過(guò)程中，為防止焊縫表面咬邊和下面產(chǎn)生熔化金屬下淌現(xiàn)象，每個(gè)斜圓圈形與焊穎中心線的斜度不得大于45度。當(dāng)焊條末端運(yùn)到斜圓上面時(shí)，電弧應(yīng)更短，并稍停片刻，然后緩慢將電弧引到焊縫的下邊，即原先電弧停留的旁邊，這樣做能有效地避免各種缺陷，使焊縫成形良好。鋼結(jié)構(gòu)焊接陶瓷襯墊批發(fā)廠家坡口盡量設(shè)在方便施焊的一側(cè)。為了方便現(xiàn)場(chǎng)加工，保證坡口角度的準(zhǔn)確，經(jīng)過(guò)換算。</p><div

+ 蛭石 + 粘合劑），其中蛭石提供支撐力。非膨脹型襯墊 – 纖維襯墊（纖維 + 粘合劑），有些纖維襯墊中不含粘合劑，其中纖維提供支撐力襯墊在后處理系統(tǒng)中是一個(gè)非常關(guān)鍵的部件，現(xiàn)有市場(chǎng)上存在著多種類(lèi)型的襯墊。威特陶瓷的襯墊有：耐高壓陶瓷襯墊、耐高溫陶瓷襯墊、焊接陶瓷襯墊、鋼結(jié)構(gòu)焊接陶瓷襯墊、橋梁陶瓷襯墊、工程機(jī)械陶瓷襯墊、造船陶瓷襯墊。 <p> <br /> </p> <p> <br
