手工鎢極氬弧工藝特點(diǎn)工作原理鎢極氬弧焊是采用鎢棒作為電極，利用氬氣作為保護(hù)氣體進(jìn)行焊接的一種氣體保護(hù)焊方法。通過鎢極與工件之間產(chǎn)生電弧，利用從焊噴嘴中噴出的氬氣流在電弧區(qū)形成嚴(yán)密封閉的氣層，使電極和金屬熔池與空氣隔離，以防止空氣的侵入。同時(shí)利用電弧熱來熔化基本金屬和填充焊絲形成熔池。液態(tài)金屬熔池凝固后形成焊縫。由于氬氣是一種惰性氣體，不與金屬起化學(xué)反應(yīng)，所以能充分保護(hù)金屬熔池不被氧化。同時(shí)氬氣在高溫時(shí)不溶于液態(tài)金屬中，所以焊縫不易生成氣孔。因此，氬氣的保護(hù)作用是有效和可靠的，可以獲得較高質(zhì)量的焊縫。焊接時(shí)鎢極不熔化，所以鎢極氬弧焊又稱為非熔化極氬弧焊。根據(jù)所采用的電源種類，鎢極氬弧焊又分為直流、交流和脈沖三種。焊不銹鋼用什么焊條？不銹鋼怎么焊接？焊接技術(shù)焊接是被焊工件的材質(zhì)（同種或異種），通過加熱或加壓或兩者并用，并且用或不用填充材料，使工件的材質(zhì)達(dá)到原子間的結(jié)合而形成長久性連接的工藝過程。那么不銹鋼焊接要點(diǎn)與注意事項(xiàng)有哪些要點(diǎn)呢？焊不銹鋼用什么焊條不銹鋼焊條可分為鉻不銹鋼焊條和鉻鎳不銹鋼焊條，這兩類焊條中凡符合國標(biāo)的，均按國標(biāo)GB/T983-2012規(guī)定考核。鉻不銹鋼具有一定的耐蝕。</p><p> 后者只預(yù)熱焊件邊緣較厚的部分。電源可采用直流正接，也可以采用交流。用交流電源焊接時(shí)，鋅的蒸發(fā)量較小。焊接參數(shù)宜采用較大的焊接電流和較快的焊接速度。厚16～20mm黃銅板的焊接參數(shù)為：焊接電流260～300A，鎢極直徑5mm，焊絲直徑～，噴嘴孔徑14～16mm，氬氣流量20～25L/min。為了減少鋅的蒸發(fā)，操作時(shí)可將填充焊絲與焊件'短接'，在填充焊絲上引弧和保持電弧，盡可能避免電弧直接作用到母材上，母材主要靠熔池金屬的傳熱來加熱熔化。焊接時(shí)，應(yīng)盡可能進(jìn)行單層焊，板厚小于5mm的接頭，比較好能一次焊完。焊后焊件應(yīng)加熱到300～400℃進(jìn)行退火處理，消除焊接應(yīng)力，以防止黃銅構(gòu)件在使用時(shí)破裂。4．黃銅碳弧焊黃銅碳弧焊時(shí)，根據(jù)母材的成分選用絲221、絲222、絲224等焊絲，也可用自制的黃銅焊絲施焊。焊接可以采用氣劑301等作熔劑。焊接應(yīng)短弧操作，以減少鋅的蒸發(fā)和燒損。藥芯焊絲工藝性能好，焊縫成形美觀采用氣渣聯(lián)合保護(hù)，獲得良好成形。</p><div
