焊嘴與工件距離：理論是越近越好；越近銅嘴與工件之間越容易打火，重慶加重鉆桿堆焊噴焊機(jī)，我們建議小電流情況下控制1-3mm；銅嘴孔徑越大焊道越寬。 </p> <p> <br /> </p> <p> 安全的操作等離子堆焊機(jī)，避免對(duì)工廠造成不必要的損失。 </p> <p> <br /> 鉆桿堆焊設(shè)備是指什么？重慶加重鉆桿堆焊噴焊機(jī)</p><div

等離子堆焊由于利用等離子弧作熱源和采用合金粉末作填充金屬，從而與其他表面堆焊方法相比較，具有以下特點(diǎn)：（1）生產(chǎn)率較高，目前熔敷率達(dá)到了5公斤/小時(shí)，接近生產(chǎn)率高的埋弧自動(dòng)焊，超過(guò)了常用的手工電弧堆焊和氧炔焰堆焊。（2）母材對(duì)合金沖淡率低，由于工藝上可調(diào)規(guī)范差數(shù)多，能主動(dòng)控制熱量輸入；合金粉末在弧柱中被預(yù)先加熱，呈噴射狀過(guò)渡到熔池，對(duì)電弧吹力有緩沖作用，熔池受熱均勻，因而可控制母材熔深，降低母材對(duì)合金的沖淡率。沖淡率可控制在5-15%范圍內(nèi)，接近氧炔堆焊，而較大低于其他方式的堆焊。（3）噴焊層成形平整、光滑，成形尺寸范圍寬并可精確控制，通過(guò)改變規(guī)范參數(shù)，一次噴焊可控制寬度5-40毫米，厚度，這是其他堆焊方法難以實(shí)現(xiàn)的。（4）噴焊層質(zhì)量和工藝穩(wěn)定性好，由于等離子弧穩(wěn)定性好，外界因素的干擾（周圍氣流的流動(dòng)，噴焊鎗距工件的高低，角度的微小變化等）對(duì)電參數(shù)（弧壓、弧電流）和電弧穩(wěn)定性影響較小，從而使工藝易于穩(wěn)定。合金粉末熔化充分，飛濺少，熔池中熔渣和氣體易于排除，容易消除焊層內(nèi)氣孔，夾渣等質(zhì)量缺點(diǎn)。由于等離子弧溫度高，熱量績(jī)中。噴焊速度快，一次熔成，使工件熱影響區(qū)小。噴焊層合金組.織晶粒細(xì)。</p><p>
