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)則地擺動焊條進行短弧施焊的操作方法；熄弧法是在封底焊時采用電弧燃燒一定時即行熄滅，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。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。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，但操作方法不當將會造成焊縫下垂，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)達國家，如德國、美國、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、焊接操作要點封底層的焊接對整個試板而言，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。</p><p>

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烈紫外線的作用下。焊絲焊補時熱影響區(qū)非常小，不會產(chǎn)生內(nèi)應力。山東RD12M焊絲生產(chǎn)廠</p><p
