紅外線輻射約為普通焊條電弧焊的1～，氬弧焊電弧產(chǎn)生的紫外線輻射約為焊條電弧焊的5～20倍。在有限空間內(nèi)焊接時(shí)，臭氧的濃度可增大到危險(xiǎn)程度，在焊接過(guò)程中，還會(huì)產(chǎn)生二氧化碳，一氧化碳等有害氣體和金屬粉塵，這些都對(duì)焊工產(chǎn)生一定的危害。所以我們?cè)诤附舆^(guò)程中要做好防護(hù)，選用電極的材料，要盡量選用放射性小的鈰鎢。磨削電極時(shí)，要戴好口罩，手套，且工作后要洗手，讓危害降到比較低。高頻電磁場(chǎng)的危害焊接通常使用高頻振蕩器的頻率為200～500kHz，電壓2500～3500V，電場(chǎng)強(qiáng)度140～190V/m。引弧時(shí)，產(chǎn)生的高頻電磁場(chǎng)強(qiáng)度在60～110V/m之間，超過(guò)參考衛(wèi)生標(biāo)準(zhǔn)(20V/m)數(shù)倍。在非熔化極氬弧焊和等離子弧焊割時(shí)，常用高頻振蕩器來(lái)激發(fā)引弧，有的交流氬弧焊機(jī)還用高頻振蕩器來(lái)穩(wěn)定電弧。人體在高頻電磁場(chǎng)作用下，能吸收一定的輻射能量，產(chǎn)生生物學(xué)效應(yīng)，主要是熱作用。高頻電磁場(chǎng)強(qiáng)度受許多因素影響，如距離，振蕩器和振蕩回路越近場(chǎng)強(qiáng)越高，反之則越低。此外，與高頻部分的屏蔽程度等有關(guān)。人體在高頻電磁場(chǎng)作用下會(huì)產(chǎn)生生物學(xué)效應(yīng)，焊工長(zhǎng)期接觸高頻電磁場(chǎng)能引起植物神經(jīng)功能紊亂和神經(jīng)衰弱。表現(xiàn)為全身不適、頭昏***、疲乏、食欲不振、***及血壓偏低等癥狀。</p><p> 三)面罩及其它防護(hù)用具面罩的主要作用是保護(hù)電焊工的眼睛和面部不受電弧光的輻射和灼傷，面罩分手持式和頭盔式兩種。面罩上的護(hù)目玻璃起到減弱電弧光并過(guò)濾紅外線、紫外線的作用。護(hù)目玻璃有不同色號(hào)、目前以黑綠色的為多，應(yīng)根據(jù)電焊工的年齡和視力情況盡量選擇顏色較深的護(hù)目玻璃以保護(hù)視力。護(hù)目玻璃外還加有相同尺寸的一般玻璃，以防金屬飛濺沾污護(hù)目玻璃。焊工用護(hù)目遮光鏡片的選用可按表11—8進(jìn)行。其它防護(hù)用品有電焊工在工作時(shí)需佩帶的**電焊手套和護(hù)腳，以及清渣時(shí)應(yīng)戴的平光眼鏡。六、交流弧焊機(jī)與直流弧焊機(jī)的比較交流弧焊機(jī)的主要優(yōu)點(diǎn)是成本低、制造維護(hù)簡(jiǎn)單，噪聲較小；缺點(diǎn)是不能適應(yīng)堿性焊條，且焊接電壓、電流容易受到電網(wǎng)波動(dòng)的干擾。直流弧焊機(jī)的優(yōu)點(diǎn)是電弧穩(wěn)定，焊條適應(yīng)性強(qiáng)；缺點(diǎn)是成本較高，制造維修較復(fù)雜，重量較重。但由于優(yōu)點(diǎn)明顯，直流弧焊機(jī)是大有前途的電焊機(jī)。表3—7列出了兩類焊機(jī)的性能比較。焊絲溫度不會(huì)持續(xù)上升至其整段發(fā)紅，抗紅能力***。</p><div
