style="text-indent:25px">為什么等離子熔覆（堆焊）不易產(chǎn)生裂紋·氣孔等缺點(diǎn)：主要原因有三。一是等離子做熱源進(jìn)行熔覆（堆焊）與埋弧焊氣保焊等熱量更加集中，離子弧穩(wěn)定性更好，沒(méi)有電極熔耗，輸出熱量均勻，便于控制，這樣使得熔鑄區(qū)熱量分布均勻，材料熔合充分均勻，排氣浮渣都充分，收縮應(yīng)力分布均勻。二是由于等離子設(shè)備控制精度高，對(duì)熔鑄區(qū)和過(guò)渡區(qū)的控制方便，且均勻度好，應(yīng)力分配更容易控制合理。三是用氬氣保護(hù)不需要各種添加劑，也不存在排氫，氧化等問(wèn)題，所以等離子熔覆（堆焊）更適合大面積，大厚度，高質(zhì)量的硬面熔鑄（如高錳·高鉻陶瓷材料等）適合于制造耐磨板、閥門、軋輥等。成都等離子合金堆焊等離子設(shè)備的研發(fā)途徑。</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

等離子粉末噴焊（PlasmaTransferredArc簡(jiǎn)稱PTA）是一種先進(jìn)的堆焊工藝。它是采用氬氣等離子電弧作熱源（轉(zhuǎn)移型等離子弧為主，非轉(zhuǎn)移型等離子弧為輔），采用粉末狀合金作填充料的自動(dòng)堆焊方法。在采用聯(lián)合型等離子弧噴焊時(shí)，一般采用兩**立的直流弧焊機(jī)作電源，分別供給非轉(zhuǎn)移弧和轉(zhuǎn)移弧。兩個(gè)電源的負(fù)極并聯(lián)在一起，通過(guò)電纜接至噴焊鎗的鎢電極（負(fù)極）。非轉(zhuǎn)移弧電源正極通過(guò)電纜接噴焊鎗噴嘴，轉(zhuǎn)移弧電源正極通過(guò)電纜接工件。冷卻水通過(guò)水冷電纜引至焊鎗，冷卻噴嘴和電極。氬氣通過(guò)電磁氣閥和浮子流量計(jì)進(jìn)入噴焊鎗。電源接通后，借助高頻火花引燃非轉(zhuǎn)移弧。再借助非轉(zhuǎn)移弧弧焰在鎢電極和工件之間造成的導(dǎo)電通道，引燃轉(zhuǎn)移弧。轉(zhuǎn)移弧引燃后，可保留或切斷非轉(zhuǎn)移弧。主要利用轉(zhuǎn)移弧在工件表面產(chǎn)生熔池。合金粉末由送粉器按需要量連續(xù)供給，借助送粉氣流（也用氬氣）送入焊鎗，并吹入電弧中。合金粉末在弧柱中被預(yù)先加熱，呈熔化或半熔化狀態(tài)，噴射到工件熔池里，在熔池里充分熔化，并排出氣體和浮出熔渣。通過(guò)調(diào)節(jié)轉(zhuǎn)移弧和非轉(zhuǎn)移弧電流，送粉量和其它工藝規(guī)范參數(shù)，來(lái)控制熔化合金粉末和傳遞給工件的熱量。隨著焊鎗和工件的相對(duì)移動(dòng)，合金熔池逐凝固。上海等離子的技術(shù)難點(diǎn)有哪些。</p><div
