有利于保證焊縫的機(jī)械性能。不重要的焊縫也可用基本金屬切條作焊絲。氣體熔劑：由硼酸甲醇的混合液（沸點(diǎn)55℃）揮發(fā)而成。由乙炔帶入火焰中與氧反應(yīng)生成硼酐（B2O3）、二氧化碳和水蒸氣。硼酐凝結(jié)到基本金屬及焊絲上。焊接時產(chǎn)生強(qiáng)烈脫氧作用，與氧化物生成硼酸鹽，以鹽膜狀態(tài)浮在熔池表面，能有效地防止鋅的蒸發(fā)。氣體熔劑已成功地應(yīng)用于黃銅的焊接和堆焊上。（2）火焰性質(zhì)：預(yù)熱時采用中性火焰，以免工件表面氧化。而焊接時應(yīng)采用輕微氧化焰，這是因?yàn)檩p微氧化焰雖然燒損一部分鋅，使熔池表面形成一層氧化鋅薄膜（熔點(diǎn)1800℃），但它支能防止熔池中的鋅大量蒸發(fā)。輕微氧化焰到何種程度為宜，一般是對好中性焰后，用手稍微調(diào)一下氧氣調(diào)節(jié)閥，聽到有“吃、吃”聲就可以了。（3）焊粉的使用方法：一般不將焊粉灑在工件上。為了節(jié)省沾焊粉時間，將焊粉倒入長槽中，再把用焊炬加熱的焊絲橫放在焊粉中滾動，使焊絲表面沾上一層焊粉（約為—1毫米厚），然后排列在傾斜的架子上，以備使用。（4）操作要點(diǎn)：焊炬上下跳動，不作橫向擺動。焊速較快。其它與紫銅氣焊相同。2．黃銅的焊條電弧焊焊條采用青銅芯焊條，如ECuSn-B（T227）、ECuAl-C（T237）。加入穩(wěn)弧劑使電弧穩(wěn)定，熔滴過渡均勻。</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(yàn)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。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。山東特種焊絲銷售</p><p
