為防止底層焊道的背面被氧化，背面也需要實施氣體保護。7、為使氬氣很好地保護焊接熔池，和便于施焊操作，鎢極中心線與焊接處工件一般應保持80~85°角,填充焊絲與工件表面夾角應盡可能地小，一般為10°左右。8、防風與換氣。有風的地方，務請采取擋網(wǎng)的措施，而在室內則應采取適當?shù)膿Q氣措施。二、不銹鋼焊接要點及注意事項1、采用平特性焊接電源，直流時采用反極性(焊絲接正極)2、一般采用純氬氣(純度為)或Ar+2%O2,流量以20~25L/min為宜，上海模具焊絲商家。3、電弧長度，不銹鋼的MIG焊接，一般都在噴射過渡的條件下來施焊，電壓要調整到弧長在4~6mm的程度。4、防風。MIG焊接容易受到風的影響，有時微風而產生氣孔，所以風速在，都應當采取防風措施。三、不銹鋼藥芯焊絲焊接要點及注意事項1、采用平特性焊接電源，直流焊接時采用反極性。使用一般的CO2焊機就可以施焊，但送絲輪的壓力請稍調松。2、保護氣體一般為二氧化碳氣體，氣體流量以20~25L/min較適宜。3、焊嘴與工件間的距離以15~25mm為宜。4、干伸長度，上海模具焊絲商家，一般的焊接電流為250A以下時約15mm，上海模具焊絲商家。?工藝性能好，焊縫成形美觀采用氣渣聯(lián)合保護，獲得良好成形。上海模具焊絲商家</p><div

熔敷金屬具有良好的抗裂性能及抗氧化性能。采用直流反接，可進行全位置焊用途:用于焊接同類型的不銹鋼、異種鋼及高鉻鋼、高錳鋼等。用途:用于焊接同類型的不銹鋼、異種鋼及高鉻鋼、高錳鋼等。A312不銹鋼焊條符合GBE309Mo-16相當AWSE309Mo-16說明:A312是鈦鈣型藥皮的Cr23Ni13Mo2不銹鋼焊條。由于焊縫中含Mo量較高，所以比A302有更好的耐蝕、抗裂及抗氧化性能。可交直流兩用，有良好的操作工藝性能。用途:用于焊接耐硫.酸介質（硫氨）腐蝕的同類型不銹鋼容器，也可作不銹鋼襯里、復合鋼板、異種鋼的焊接。A312SL不銹鋼焊條符合GBE309Mo-16相當AWSE309Mo-16說明:A312SL是鈦鈣型藥皮的不銹鋼型的滲鋁鋼焊條。熔敷金屬與母材過渡平整，能有效地保護滲鋁層。交直流兩用，可進行全位置焊接。熔敷金屬具有與滲鋁鋼相匹配的耐腐蝕性和抗高溫氧化性。用途:焊接Q235、20g和Cr5Mo等鋼材表面滲鋁部件，也可作異種鋼材的焊接。A402不銹鋼焊條符合GBE310-16相當AWSE310-16說明:A402是鈦鈣型藥皮的Cr26Ni21純奧氏體不銹鋼焊條。熔敷金屬900~1100℃高溫條件下具有優(yōu)良的抗氧化**直流兩用，有良好的焊接工藝性能。用途:用于在高溫條件下工作的同類型耐熱不銹鋼焊接。上海模具焊絲商家在氣焊和鎢極氣體保護電弧焊時，焊絲用作填充金屬。</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生大量的金屬焊接粉塵，焊接產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年來國內外開展了一些關于電焊作業(yè)生殖毒性的研究，主要涉及男工**質量、女工生殖結局及損害機制。研究表明：電焊女工月經的經量增加、周期縮短、經期延長、白帶增加，自然流產、早產、痛經、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。</p><p> 焊接重要的焊接構件及合金鋼焊件，為了防止氫致裂紋的產生，提高焊縫金屬和熱影響區(qū)的韌性，要選用低氫堿性焊條施焊。使用堿性低氫焊條**重要一環(huán)，是焊條的烘干，必須按照烘干要求進行，一般焊前烘干工藝要求為350°×1小時，雨季或潮濕天氣可提高到400°×1小時。烘干不好，后果很嚴重，不但會產生焊接缺點，也會嚴重影響焊接工藝性能，千萬不要大意！其次，焊件焊接處要清理干凈，徹底***油污、銹跡、水分、雜質、臟東西，合理的焊接工藝這一點都寫得很清楚?！锊僮饕c堿性低氫焊條的操作，主要是采用短弧操作，電弧盡量壓短。焊接時，手把要穩(wěn)，電弧越短越好。運條時，焊條傾角與焊縫前進方向成85°-90°，與左右保持垂直，如果焊條傾角過大或左右不正，即使是壓低了電弧，也不是真正的短弧。短弧焊的目的是更好的應用渣氣聯(lián)合保護功能，保護熔池不受空氣侵襲，保護熔池焊接冶金反應順利進行，減少焊接缺點的產生。多層焊時，每層焊肉要薄些，以利于熔池中氣體逸出，熔渣容易浮出，出現(xiàn)缺點也容易清理。多層焊，每層焊縫方向相反，以利于整體焊縫熱量均勻。操作手法采用畫圓圈式的橫向擺動，熔池冷卻速度變慢，利于氣體逸出，避免產生氣孔，提高焊縫質量。請按焊絲的類別、規(guī)格分類存放、防止錯用。</p><div

此時應選用抗裂性較好的堿性焊條。（4）根據(jù)焊件的工作條件、使用性能和幾何形狀選用焊條1）載荷性質在承受動載荷或沖擊載荷情況下，除了要求保證抗拉強度外，還對焊縫金屬的塑性和沖擊韌度有較高的要求，推薦使用堿性焊條。2）工作介質若焊件是在腐蝕介質中工作的不銹鋼件或其它耐腐蝕材料，必須根據(jù)介質種類、濃度、工作溫度等情況，選擇或按設計規(guī)定采用相應的不銹鋼焊條或其它耐腐蝕焊條。3）幾何形狀根據(jù)焊件幾何形狀的復雜程度、剛性的大小、焊接坡口制備情況以及焊接部位所處的位臵選用焊條，應遵循下列原則：[1]形狀復雜或大厚度的焊件，由于焊縫金屬在冷收縮時會產生較大的應力，易形成裂紋，因此應選用抗裂性較高的焊條，如堿性焊條。[2]某些難以清理干凈的焊接部位，應選用氧化性強，對鐵銹、氧化皮和油垢敏感性較小的酸性焊條，以免產生氣孔等缺點。[3]焊接部件因受條件限制不能翻轉時，必須選用能在任何空間位臵（全位臵）進行焊接的焊條。（5）根據(jù)工地設備和勞動條件選用焊條1）根據(jù)工地設備狀況選用焊條[1]在沒有直流焊機的工作場所，不能選用***用直流電源的堿性焊條，應選用交流焊條或交、直流兩用的堿性焊條。[2]對于某些焊件，若選用一般焊條。含有造渣、造氣和穩(wěn)弧成分的藥芯焊絲焊接時不需要保護氣體，稱自保護藥芯焊絲。上海焊絲</p><p
