等離子粉末噴焊（PlasmaTransferredArc簡稱PTA）是一種先進的堆焊工藝。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堆焊方法。在采用聯(lián)合型等離子弧噴焊時，一般采用兩**立的直流弧焊機作電源，分別供給非轉(zhuǎn)移弧和轉(zhuǎn)移弧，重慶加重鉆桿堆焊定制。兩個電源的負極并聯(lián)在一起，通過電纜接至噴焊鎗的鎢電極（負極）。非轉(zhuǎn)移弧電源正極通過電纜接噴焊鎗噴嘴，轉(zhuǎn)移弧電源正極通過電纜接工件。冷卻水通過水冷電纜引至焊鎗，冷卻噴嘴和電極。氬氣通過電磁氣閥和浮子流量計進入噴焊鎗。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，重慶加重鉆桿堆焊定制，重慶加重鉆桿堆焊定制，在熔池里充分熔化，并排出氣體和浮出熔渣。通過調(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移動，合金熔池逐凝固。上海鉆桿堆焊設(shè)備哪家牛?重慶加重鉆桿堆焊定制</p><div

為了保護鉆具和套管在鉆井過程中不至于過度磨損，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)合強度等于鎳基合金粉末涂層大體相當(dāng)，因此在不少場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)用過程中，容易出現(xiàn)耐磨帶的開裂和剝落。 </p> <p> <br />

等離子粉末堆焊，一般而言,堆焊的金屬首先應(yīng)滿足焊件的使用條件;其次考慮堆焊的金屬焊接性要好,再后適當(dāng)選擇比較經(jīng)濟的堆焊金屬。常見的工作環(huán)境條件下使用的堆焊金屬有:高應(yīng)力金屬間磨損選用亞共晶鈷基合金、含金屬間化合物的鈷基合金；低應(yīng)力金屬間磨損選用堆焊用低合金鋼；金屬間磨損＋腐蝕或氧化選用大多鈷基合金或鎳基合金；低應(yīng)力磨料磨損、沖擊浸蝕、磨料浸蝕選用高合金鑄鐵；低應(yīng)力嚴重磨料磨損、切割刃選用碳化物；氣蝕浸蝕選用鈷基合金；嚴重沖擊選用高合金錳鋼；嚴重沖擊＋腐蝕＋氧化選用亞共晶鈷基合金；高溫下金屬間磨損選用亞共晶鈷基合金、含金屬間化合物的鈷基合金；鑿削式磨料磨損選用奧氏體錳鋼；熱穩(wěn)定性高溫蠕變強度(540℃)選用鈷基合金碳化物型鈷基合金。上海鉆桿堆焊未來的發(fā)展方向。重慶PTA鉆桿堆焊堆焊機</p><p

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：主要原因有三。一是等離子做熱源進行熔覆（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，對熔鑄區(qū)和過渡區(qū)的控制方便，且均勻度好，應(yīng)力分配更容易控制合理。三是用氬氣保護不需要各種添加劑，也不存在排氫，氧化等問題，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。重慶加重鉆桿堆焊定制</p><p
