手工鎢極氬弧工藝特點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。同時氬氣在高溫時不溶于液態(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與注意事項有哪些要點呢？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。為了防止焊絲生銹,須對焊絲(除不銹鋼焊絲外)表面進(jìn)行特殊處理。</p><div

其癥狀是出現(xiàn)兩眼高度羞明、流淚、異物感、刺痛、眼瞼***、痙攣、并伴有***和視物模糊。焊接煙塵的危害焊接過程中會產(chǎn)生大量的金屬焊接粉塵，焊接產(chǎn)生的金屬粉直徑很小，較容易吸肺部，因直徑很小很難排出體外，故發(fā)生病變。焊接電流強(qiáng)度越大粉塵濃度越高。在焊接粉塵濃度較大的情況下，又沒有相應(yīng)的排塵措施時，長期接觸焊接粉塵能引起焊工塵肺、錳中毒和金屬熱等職業(yè)疾病。生殖毒性，近10年來國內(nèi)外開展了一些關(guān)于電焊作業(yè)生殖毒性的研究，主要涉及男工**質(zhì)量、女工生殖結(jié)局及損害機(jī)制。研究表明：電焊女工月經(jīng)的經(jīng)量增加、周期縮短、經(jīng)期延長、白帶增加，自然流產(chǎn)、早產(chǎn)、痛經(jīng)、均較對照組高。錳中毒男工**外觀呈均勻灰白色，PH值正常，平均液化時間比對照組延長。檢驗結(jié)果證明，錳中毒男工平均一次**量、精子總數(shù)、精子存活率及活動精子率均比對照組下降，錳中毒男工精子畸形率明顯高于對照組。認(rèn)為金屬錳能夠影響男工生精系統(tǒng)，對精子的發(fā)育有直接毒作用，并能殺傷精子，從而引起男性**質(zhì)量的改變。國外也有報道電焊作業(yè)工人性***分泌改變，精子質(zhì)量下降，但對子代的性別比例沒有影響有害氣體的危害在焊接電弧高溫和強(qiáng)烈紫外線的作用下。安徽模具焊絲供貨廠</p><p
