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(wú)法比擬。由于等離子弧為連續(xù)工作，造成機(jī)體冷卻相對(duì)較慢，形成的過(guò)渡區(qū)域比激光熔覆要深一些，這對(duì)硬面材料熔覆來(lái)說(shuō)，應(yīng)力會(huì)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(lái)，其電源·噴鎗·送粉器·擺動(dòng)器等，技術(shù)門檻低，容易制造，可靠性好，維護(hù)使用簡(jiǎn)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(duì)環(huán)境要求低，對(duì)材料適應(yīng)***。隨著電氣技術(shù)的進(jìn)步，我國(guó)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(lái)更靈活方便，輔助工裝的造價(jià)便宜。重慶等離子粉末堆焊鉆桿堆焊**設(shè)備上海鉆桿堆焊的發(fā)展方向是哪里？</p><div

style="text-indent:25px">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)。火焰收口在環(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 style="text-indent:25px"> 關(guān)于焊接電流在等離子堆焊過(guò)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(guò)程中如果電流過(guò)小，填充金屬不易熔化，堆焊層與工件無(wú)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(guò)大，工件熔化過(guò)較多，在增加稀釋率的同時(shí)，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(lái)選定的，電流過(guò)大過(guò)小都會(huì)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(gè)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(duì)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(shí)，焊接電流要減?。环粗?，當(dāng)?shù)入x子氣流量減小時(shí)，焊接電流須增加。上海鉆桿堆焊能夠賺錢嗎？</p><div

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 />
