在堆焊過(guò)程中，焊炬除了按上述方法作階梯式的向前移動(dòng)外，還需沿著堆焊面作橫向擺動(dòng)，這樣可以提高堆焊層的均勻性和平整度。每堆焊一層可得到2～3mm厚的堆焊層，每層連續(xù)一次堆焊好。如果需要得到更厚的堆焊層，則須多層堆焊，層間須用砂輪或鋼絲刷進(jìn)行清理和平整，而后再堆焊下一層。根據(jù)需要可以用火焰重新熔化堆焊層（重熔），以減少堆焊層金屬的缺點(diǎn)，提高堆焊層質(zhì)量。（3）堆焊時(shí)，焊絲的熔化端、熔池必須始終處于“三倍乙炔過(guò)剩焰”的保護(hù)之中，使它們與空氣隔絕。不得將焊炬急速地從熔池表面移開(kāi)。堆焊搭接時(shí)，應(yīng)使接頭重疊15～20mm，收尾時(shí)須將焊炬繼續(xù)前移40～50mm，焊炬逐漸抬起，火焰逐漸離開(kāi)熔池，使熔池逐漸縮小。這樣，接頭處的冷卻速度緩慢，不至于產(chǎn)生接頭疏松、縮孔、火口裂紋等缺點(diǎn)?；鹧媸湛谠诃h(huán)縫的內(nèi)側(cè)為好，這樣可以減少堆焊接頭的收縮應(yīng)力。等離子粉末堆焊是以等離子弧作為熱源，應(yīng)用等離子弧產(chǎn)生的高溫將合金粉末與基體表面迅速加熱并一起熔化、混合、擴(kuò)散、凝固，等離子束離開(kāi)后自激冷卻，形成一層高性能的合金層，從而實(shí)現(xiàn)零件表面的強(qiáng)化與硬化的堆焊工藝。 </p><p> 為了保護(hù)鉆具和套管在鉆井過(guò)程中不至于過(guò)度磨損，采用堆焊方式或(其他方法)將堆焊材料沿鉆桿接頭圓周方向堆焊(或熔敷)寬約30～50mm、厚2～3mm的環(huán)形帶。此環(huán)形帶即稱之為鉆桿接頭耐磨帶。目前在工程上使用的耐磨帶堆焊材料主要有鐵基合金粉末、碳化鎢顆粒和耐磨帶焊絲。 </p> <p> <br /> </p> <p> 一、鐵基合金粉末 </p> <p> <br /> </p> <p> 鐵基合金粉末是通過(guò)調(diào)整18-8型或Cr13型不銹鋼的Ni、Cr含量，并添加B、Si元素而成的。鐵基合金粉末的噴涂層硬度、致密性、結(jié)合強(qiáng)度等于鎳基合金粉末涂層大體相當(dāng)，因此在不少場(chǎng)合下可代替鎳基合金粉末，但涂層的韌性低于鎳基合金粉末涂層。鐵基合金粉末涂層具有良好的耐磨性。 </p> <p> <br /> </p> <p> 鉆桿接頭耐磨帶堆焊鐵基合金粉末采用的是等離子弧堆焊方法。等離子弧堆焊是利用轉(zhuǎn)移型等離子弧作為熱源，以鐵基合金粉末作填充金屬的一種堆焊工藝。其焊接溫度較高，容易造成局部組.織變大，且重復(fù)堆焊性變差，在應(yīng)用過(guò)程中，容易出現(xiàn)耐磨帶的開(kāi)裂和剝落。 </p> <p> <br />

截齒等離子堆焊層的工況條件比較復(fù)雜，截齒在切割煤巖過(guò)程中除了承受周期性壓應(yīng)力、切應(yīng)力和沖擊載荷作用外，還要承受長(zhǎng)時(shí)間磨粒磨擦、沖擊產(chǎn)生的溫升作用以及腐蝕介質(zhì)的腐蝕作用。因此，截齒堆焊耐磨層的作業(yè)環(huán)境較為復(fù)雜、惡劣。 </p> <p> 截齒等離子堆焊層的性能要求比較苛刻，首先自身要耐磨，也就是說(shuō)在采煤過(guò)程中，截齒堆焊層與煤層間會(huì)發(fā)生持續(xù)磨擦運(yùn)動(dòng)，截齒堆焊層必須經(jīng)受住煤層的長(zhǎng)時(shí)間磨損。 </p> <p> 在這種情況下，堆焊層的硬度、耐磨性越高越好；其次，必須考慮截齒在切割煤巖過(guò)程中不可避免的沖擊載荷作用，如果堆焊層的硬度太高，金屬韌性較差，堆焊層金屬容易發(fā)生崩裂或斷裂。因此，堆焊層的硬度不一定是越高越好，而是應(yīng)當(dāng)綜合考慮，使其具有良好的綜合抗磨性能。 </p> <p> 同時(shí)需要注意，煤巖材料特性對(duì)堆焊耐磨層的影響。煤質(zhì)的軟硬以及夾矸石的多少，對(duì)截齒堆焊層磨損影響非常明顯。煤質(zhì)較軟、夾矸石較少的煤巖，截齒切割阻力較小，采煤機(jī)牽引阻力也較小，截齒的磨損率較小；反之，截齒的磨損率較大。 </p> <p> <br /> 上海鉆桿堆焊的應(yīng)用有哪些？重慶等離子鉆桿堆焊修復(fù)機(jī)</p><p
