由于刻槽鉆桿接頭在接受猛烈的磨損的同時(shí)還接受沖蝕磨損,招致刻槽鉆桿接頭磨損快。為了進(jìn)步刻槽鉆桿接頭的耐磨性，就呈現(xiàn)了刻槽鉆桿接頭耐磨帶，所謂的刻槽鉆桿接頭耐磨帶就是為了維護(hù)刻槽鉆桿在鉆井過程中不至于過度磨損，采用堆焊、噴焊方式將耐磨焊絲沿刻槽鉆桿接頭圓周方向堆焊、噴焊，堆焊、噴焊寬約30-50mm，厚2-3mm的環(huán)形帶，此環(huán)形帶及稱之為刻槽鉆桿接頭耐磨帶?？滩坫@桿接頭耐磨帶因其具有優(yōu)于刻槽鉆桿接頭自身的耐磨性能，同時(shí)可以降低對(duì)套管的磨損的優(yōu)點(diǎn)，從而對(duì)處理刻槽鉆桿與套管的磨損這一問題起到關(guān)鍵性的作用。

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(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選定的，電流過大過小都會(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??；反之，當(dāng)?shù)入x子氣流量減小時(shí)，焊接電流須增加。天津等離子</p><p
