電弧周圍形成多種有害氣體，其中主要有臭氧、氮氧化物、一氧化碳和氟化氫等。臭氧是一種刺激性氣體，呈淡藍(lán)色。濃度較高時(shí)，發(fā)出腥臭味；高濃度臭氧還略帶酸味。臭氧對(duì)人體的主要危害是對(duì)呼吸道及肺有強(qiáng)烈刺激作用。往往引起咳嗽、胸悶、食欲不振、疲勞無力、頭暈、全身疼痛等，嚴(yán)重時(shí)還會(huì)引起***和肺水腫等。氮氧化物是刺激性氣體。二氧化氮呈紅褐色，具有特殊臭味。氮氧化物對(duì)人體的危害主要是對(duì)肺組.織的刺激作用。其被吸人呼吸道后，在肺泡內(nèi)逐漸與水作用形成硝酸和亞硝酸，對(duì)肺組.織產(chǎn)生強(qiáng)烈刺激和腐蝕作用，引起中毒。慢性中毒的主要癥狀是神經(jīng)衰弱，如***、***、食欲不振、體重下降。濃度高的氮氧化物能引起急性中毒，其中毒輕者，*發(fā)生急性***；重度中毒時(shí)，引發(fā)咳嗽激烈、呼吸困難、虛脫、全身軟弱無力等癥狀。氮氧化物對(duì)人體的作用也是可逆的，隨著脫離作業(yè)時(shí)間的增長(zhǎng)，其不良影響逐漸減少或消除。在鎢極氬弧焊時(shí)，如果不采取通風(fēng)措施，其濃度往往超過衛(wèi)生標(biāo)準(zhǔn)十幾倍，甚至幾十倍。我國(guó)規(guī)定的氮氧化物(換算成二氧化氮)的衛(wèi)生標(biāo)準(zhǔn)為5mg／m3。在焊接過程中，通常臭氧和氮氧化物同時(shí)存在，因此它們的毒性更大。一般情況下。上海NH45R焊絲供應(yīng)商?焊絲包裝成卷或成桶以避免線材相互糾纏或折損。</p><div

1、焊接方法板狀仰焊的焊接有2種方法：連弧法及熄弧法。連弧法是通過連續(xù)而有規(guī)則地?cái)[動(dòng)焊條進(jìn)行短弧施焊的操作方法；熄弧法是在封底焊時(shí)采用電弧燃燒一定時(shí)即行熄滅，然后再引燃、再熄滅，從而使熔池金屬迭加成形的方法。這2種方法各有所長(zhǎng)。熄弧法可以保證封底焊縫有良好的成形，能有效地控制焊縫下垂、頂面內(nèi)凹，缺點(diǎn)是由于焊接過程處于間斷狀態(tài)，容易出現(xiàn)氣孔、夾渣等缺點(diǎn)。連弧法可以使焊接過程連續(xù)化，能夠有效地保證焊接質(zhì)量，但操作方法不當(dāng)將會(huì)造成焊縫下垂，表面內(nèi)凹。比較2種焊接方法，連弧焊更值得推廣。在一些工業(yè)發(fā)達(dá)國(guó)家，如德國(guó)、美國(guó)、日本等，生產(chǎn)中都要求采用這種焊接方法。2試板及工藝要求試板要求試板材質(zhì)為Q235B，規(guī)格為100mm×12mm×300mm。采用E5015（J507）焊條，焊接位置為仰焊，要求單面焊雙面成形。坡口形式如圖1所示。焊接工藝參數(shù)焊接工藝參數(shù)見表1。表1焊接工藝參數(shù)焊條角度施焊過程中焊條與焊接方向的夾角如圖2所示。3、焊接操作要點(diǎn)封底層的焊接對(duì)整個(gè)試板而言，封底層的焊接是關(guān)鍵，在焊接過程中，焊接熔池金屬的自身重力在電弧作用力和液態(tài)金屬的表面張力作用下處于平衡狀態(tài)。具體操作是地。上海SM2R焊絲工廠</p><p
