1954年哈爾濱鍋爐廠從德國引進氬弧焊是在普通電弧焊的原理的基礎上,利用氬氣對金屬焊材的保護,通過高電流使焊材在被焊基材上熔化成液態(tài)形成熔池,使被焊金屬和焊材達到冶金結合的一種焊接技術,由于在高溫熔融焊接中不斷送上氬氣,使焊材不能和空氣中的氧氣接觸,從而防止了焊材的氧化。手工鎢極氬弧焊時選擇電源的種類和極性的方法手工鎢極氬弧焊的電源有直流電源和交流電源,直流電源有直流正接法和直流反接法。直流正接法:焊件接正極,鎢極接負極,這樣焊接時,電子高速沖向焊件,焊接溫度高,熔池深而窄。正離子沖向鎢極,鎢極熱量低損耗小。該方法適用于耐熱鋼、合金鋼、不銹鋼、銅、鈦等金屬的焊接。直流反接法:焊件接負極,鎢極接正極,焊接時電子高速沖向鎢極,鎢極熱量高,消耗快,故一般不使用。用于焊接高熔點氧化膜的鋁、鎂及其合金。交流電源由于極**替變化,它既有“陰極霧化”作用,又有鎢極消耗比直流反接法少的特點,適用于鋁、鎂及其合金的焊接。手工鎢極氬弧焊時噴嘴的選擇方法噴嘴大小和形狀直接影響氬氣保護區(qū)的保護范圍和效果,常用的噴嘴有6號,7號,8號,10號。噴嘴直徑的選擇不宜過大,否則會妨礙操作,浪費氬氣;但也不宜過小,否則熔池保護不好,容易產生缺點。</p><p>

電感線圈的感抗電壓降使電焊機獲得較低的工作電壓，這是電焊機具有陡降外特性的原因。引弧時，電焊機能供給較高的電壓和較小的電流，當電弧穩(wěn)定燃燒時，電流增大，而電壓急劇降低；當焊條與工件短路時，也限制了短路電流。焊接電流調節(jié)分為粗調、細調兩檔。電流的細調靠移動鐵芯4改變變壓器的漏磁來實現。向外移動鐵芯，磁阻增大，漏磁減小，則電流增大，反之，則電流減少。電流的粗調靠改變次級繞組的匝數來實現。該電弧焊機的工作條件為應在海拔不超過1000m，周圍空氣溫度不超過+40℃、空氣相對濕度不超過85％等條件下使用，不應在有害工業(yè)氣體、水蒸汽、易燃、多灰塵的場合下工作。二、直流弧焊機(一)結構由于整流或直流弧焊機與直流弧焊發(fā)電機比較，因沒有機械旋轉部分，具有噪音小，空載損耗小、效率高、成本低和制造維護簡單等優(yōu)點。因此，有取代直流弧焊發(fā)電機的趨勢，在這里只介紹整流式直流弧焊機。整流式直流弧焊機常用型號如ZXG—300、ZXG—400等。硅整流電弧焊機是利用硅半導體整流元件(二極管)將交流電變?yōu)橹绷麟娮鳛楹附与娫础D3—10為硅整流電弧焊機的結構示意圖。選擇具有熔化溫度低于母材的填充金屬，可**減小熱影響區(qū)中晶間裂紋傾向。江西模具焊絲供應商</p><p

主回路斷電。同時Jc-2斷開，控制回路斷電，焊機全部停止工作。焊接電流的調節(jié)依靠面板上的電流調節(jié)控制器，來改變磁放大器控制或線圈中直流電大小使鐵芯中的磁通發(fā)生相應變化，從而調整了焊接電流的大小。熱將接線板燒毀或使由焊鉗過熱而無法工作。三、負載持續(xù)率焊接設備銘牌中都標有負載持續(xù)率。負載持續(xù)率是用來表示焊接設備工作狀態(tài)的參數，它是在選定的工作時間周期內允許焊接設備連續(xù)負載的時間。眾所周知，焊接設備工作時會發(fā)熱，溫升過高會把焊接設備的線包絕緣燒毀(一般焊接設備的溫度不得超過60～80℃)。溫升與焊接電流大小有關，同時也與焊機使用狀態(tài)有關，連續(xù)運轉與斷續(xù)使用時溫升情況不一樣。負載持續(xù)率計算方法如下：標準規(guī)定：500A以下的焊接設備選定的工作時間周期為5分鐘。計算時，每個5分鐘內測出電弧燃燒時間，代入式中即得出焊機負載持續(xù)率。表3—3和表3—4給出了交流弧焊機BX3一300的負載持續(xù)率和硅整流弧焊機ZXG一300的負載持續(xù)率及相應的工作電流。表3—3BX3—300交流弧焊機負載持續(xù)率負載持續(xù)率(％)焊接電流(A)表3—4ZXG—300硅整流弧焊機負載持續(xù)率負載持續(xù)率(％)焊接電流(A)四、焊機的外特性在規(guī)定范圍內。安徽激光焊絲銷售</p><p
