為了解決截齒在采煤過程中的快速磨損失效問題，采用堆焊方式（或其他冶金方式）在截齒錐頂（硬質(zhì)合金刀頭）以下齒體部位，沿圓周方向堆焊一個寬度約20-30mm、厚度2-3mm的環(huán)形帶。此環(huán)形帶即稱之為耐磨堆焊層。常用的耐磨堆焊材料為馬氏體堆焊合金（Ｄ３１７，Ｄ３２７，ＤＧ７等）、高鉻Fe-Cr-C合金系（Ｄ６８８，Ｄ６３８等）、碳化鎢、碳化鈮等。從機(jī)理上講，截齒耐磨堆焊層的作用是： </p> <p> <br /> </p> <p> 1、彌補(bǔ)或改變因硬質(zhì)合金刀頭釬焊工藝在齒體圓周形成的性能劣化現(xiàn)象（指先熱處理后釬焊工藝生產(chǎn)的截齒）。 </p> <p> <br /> </p> <p> 2、進(jìn)一步優(yōu)化或強(qiáng)化刀頭部分使用性能。當(dāng)然，重慶房車鉆桿堆焊房車，采用先釬焊刀頭后整體熱處理截齒的制造工藝時，后者的作用更為突出。然而，實(shí)際情況并不簡單，截齒耐磨堆焊層的出現(xiàn)和使用，重慶房車鉆桿堆焊房車，將截齒刀頭與被切割煤巖之間的磨擦、沖擊等作用，重慶房車鉆桿堆焊房車，轉(zhuǎn)換為或部分轉(zhuǎn)換為堆焊層與被切割煤巖之間的磨擦、沖擊等作用。它們之間的磨擦磨損、沖擊損傷等，不僅取決于兩個接觸體材料的特性及其匹配行為，同時還受到采煤過程中諸多因素的影響。

等離子堆焊技術(shù)特點(diǎn)：微束等離子熔覆機(jī)所采用的等離子束，是一種電離弧，比弧焊機(jī)熱量更集中，所以加熱速度更快，為了獲得更集中的離子束，一般采用高壓縮比孔徑，小電流，以便控制基體溫度不致太高，避免引起退火變形。當(dāng)然這與YAG激光器加熱速度無法比擬。由于等離子弧為連續(xù)工作，造成機(jī)體冷卻相對較慢，形成的過渡區(qū)域比激光熔覆要深一些，這對硬面材料熔覆來說，應(yīng)力會釋放的好一些。2.設(shè)備特點(diǎn)：微束等離子熔覆設(shè)備是在直流焊機(jī)的基礎(chǔ)上發(fā)展而來，其電源·噴鎗·送粉器·擺動器等，技術(shù)門檻低，容易制造，可靠性好，維護(hù)使用簡單，耗電少，使用成本低，通用性好，生產(chǎn)成本低，適應(yīng)性好，便于規(guī)?；a(chǎn)，效益明顯，對環(huán)境要求低，對材料適應(yīng)***。隨著電氣技術(shù)的進(jìn)步，我國的焊機(jī)技術(shù)水平已經(jīng)具備足夠的支持能力。另外設(shè)備體積小，重量小，焊鎗可以手持把握，這使它使用起來更靈活方便，輔助工裝的造價便宜。</p><p style="text-indent:25px"> 關(guān)于焊接電流在等離子堆焊過程中，**重要的工藝參數(shù)是焊接電流，隨著焊接電流的增加，等離子弧能量增大，熔化和穿透能力增加。在堆焊過程中如果電流過小，填充金屬不易熔化，堆焊層與工件無法形成良好的冶金結(jié)合，電弧不穩(wěn)定，容易造成氣孔、夾雜及未熔合等多種缺點(diǎn)。反之，如果電流過大，工件熔化過較多，在增加稀釋率的同時，增加了堆焊材料的燒損，降低堆焊層硬度；此外，由于較大的熱輸入量，工件還易燒穿焊壞，造成保護(hù)不良、氧化物多、咬邊等嚴(yán)重的焊接缺點(diǎn)，影響堆焊質(zhì)量。焊接電流主要根據(jù)工件材料及堆焊速度和焊粉種類來選定的，電流過大過小都會影響焊后性能。此外，較大的焊接電流還可能引起雙弧現(xiàn)象。因此，在選定焊鎗及噴嘴的結(jié)構(gòu)后，焊接電流只能限定在一定范圍之內(nèi)，而這個范圍是與其他焊接參數(shù)，如等離子氣流量和焊接速度等參數(shù)相關(guān)。在設(shè)定了其他堆焊參數(shù)后，焊接電流和焊接速度的對應(yīng)關(guān)系：焊接速度增加，相應(yīng)焊接電流也須增加；反之，焊接速度降低，焊接電流要減小，當(dāng)?shù)入x子氣流量增加時，焊接電流要減?。环粗?，當(dāng)?shù)入x子氣流量減小時，焊接電流須增加。上海鉆桿堆焊設(shè)備就選箴拓自動化設(shè)備（上海）有限公司。</p><div

石油鉆桿接頭是在石油勘探開采鉆井時，用于連接上、下鉆桿的重要部件，由于其長期工作在含砂多，且有一定腐蝕性介質(zhì)的井下，所以要求其具有優(yōu)良的耐磨、耐蝕性能。為了改善其耐磨、耐蝕性能，提高其使用壽命，目前國內(nèi)許多企業(yè)采用粉末等離子噴焊的方法在其接頭部位噴焊一層耐磨帶。實(shí)驗(yàn)結(jié)果表明，噴焊層主要由：γ-Fe、Cr23C6、(Cr,Fe)7C3以及NiB、萊氏體等化合物相組成。焊層冶金結(jié)合較好，**致密，稀釋率低，無裂紋、夾雜等缺點(diǎn)。同時擁有較高的硬度（55～68HRC）和耐磨性，具有較大的應(yīng)用價值。2、鉆桿是石油天然氣行業(yè)進(jìn)行油氣資源勘探，開發(fā)過程中不可或缺的工具，是組成鉆柱的主要部件。在石油勘探開采鉆井時，鉆桿接頭用于連接上、下鉆桿，是石油鉆桿的薄弱環(huán)節(jié)，80%以上的鉆桿***出現(xiàn)在這個部位。因此提高鉆桿接頭的質(zhì)量，是降低***的關(guān)鍵。3、據(jù)了解，目前國內(nèi)大部分油田的鉆井深度都達(dá)到了幾百米，有的甚至更深，達(dá)到幾千米，而且?guī)r層復(fù)雜堅硬，鉆桿在工作過程中，其外壁尤其是接頭部位要與井壁或套管接觸，所以承受著劇烈的磨損。由于鉆桿接頭周圍接觸面存在很多硬質(zhì)點(diǎn)，所以磨損主要以磨粒磨損為主，特別是下部目的層段使用屏蔽暫堵鉆井液時。上海鉆桿堆焊的發(fā)展方向是什么？重慶等離子鉆桿堆焊修復(fù)機(jī)</p><p

在堆焊過程中，焊炬除了按上述方法作階梯式的向前移動外，還需沿著堆焊面作橫向擺動，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，焊絲的熔化端、熔池必須始終處于“三倍乙炔過剩焰”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。堆焊搭接時，應(yīng)使接頭重疊15～20mm，收尾時須將焊炬繼續(xù)前移40～50mm，焊炬逐漸抬起，火焰逐漸離開熔池，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。重慶房車鉆桿堆焊房車</p><p
