聲測(cè)管主要是由接頭和直管焊接在一起的，在進(jìn)行焊接的時(shí)候一定要注意以下幾點(diǎn)。1、焊條使用時(shí)應(yīng)保持干燥，鈦鈣型應(yīng)經(jīng)150℃干燥1小時(shí)，低氫型應(yīng)經(jīng)200-250℃干燥1小時(shí)(不能多次重復(fù)烘干，否則藥皮容易開(kāi)裂剝落)，防止焊條藥皮粘油及其它臟物，以免致使焊縫增加含碳量和影響焊件質(zhì)量。樁基聲測(cè)管焊接時(shí)，受到重復(fù)加熱析出碳化物，降低耐腐蝕性和力學(xué)性能。焊后硬化性較大，容易產(chǎn)生裂紋。若采用同類型的焊條焊接，必須進(jìn)行300℃以上的預(yù)熱和焊后700℃左右的緩冷處理。若焊件不能進(jìn)行焊后熱處理，則應(yīng)選用鉻鎳不銹鋼焊條。2、為改善聲測(cè)管耐蝕性能及焊接性而適當(dāng)增加適量穩(wěn)定性元素Ti、Nb、Mo等，焊接性較好一些，采用同類型的鉻不銹鋼焊條時(shí)，應(yīng)進(jìn)行200℃以上的預(yù)熱和焊后800℃左右的回火處理。若焊件不能進(jìn)行熱處理，則應(yīng)選用鉻鎳不銹鋼焊條。要求控制曲率半徑。比如半徑長(zhǎng)度為，那么曲率半徑必須在所要求的公差范圍之內(nèi)。由于這些管件大多數(shù)用于焊接，為了提高焊接質(zhì)量，端部都車成坡口，留一定的角度，帶一定的邊，這一項(xiàng)要求也比較嚴(yán)，邊多厚，角度為多少和偏差范圍都有規(guī)定，幾何尺寸上比管件多了很多項(xiàng)。樁基聲測(cè)管表面質(zhì)量和機(jī)械性能基本和管子是一樣的。為了焊接方便。昆明聲測(cè)管批發(fā)專業(yè)聲測(cè)管密封性好，云南貿(mào)軒商貿(mào)有限公司。</p><div

樁底聲測(cè)管彎曲因施工不當(dāng)，造成樁底聲測(cè)管向內(nèi)彎曲，間距變小，使發(fā)射與接收換能器不保持平行，超聲脈沖聲速異常偏高，波幅降低，聲速曲線不正常。由于樁底是缺陷易發(fā)生部位，根據(jù)此類曲線很難判定樁底是否存在缺陷，很可能發(fā)生漏判、誤判，給工程留下安全隱患。2．2 樁身聲測(cè)管傾斜或彎曲變形聲測(cè)管綁扎不牢或綁扎間距過(guò)大，在澆筑混凝土過(guò)程中，聲測(cè)管受混凝土擠壓發(fā)生傾斜或彎曲變形，管間距離變大或變小，直接影響檢測(cè)結(jié)果的分析判定，甚至無(wú)法給出樁身完整性類別，只能采取鉆芯或其他可靠的方法進(jìn)行檢測(cè)，影響正常的施工。<span
