注：1、直徑不大于、E5015、E5016和E5018型焊條及直徑不大于，可適用于立焊和仰焊。2、E4322型焊條適宜單道焊。焊條型號舉例如下：例14、焊條的選用（1）結(jié)構(gòu)鋼（低碳鋼、中碳鋼、普通低合金鋼）焊條的選用采用結(jié)構(gòu)鋼制造的焊接結(jié)構(gòu)，大多要求焊縫金屬與母材等強度，此時可按結(jié)構(gòu)鋼的強度選擇相應強度等級的焊條。選擇時應注意以下兩點：1）鋼材的強度等級是按屈服點劃分的，而結(jié)構(gòu)鋼焊條的強度等級系指其抗拉強度的比較低保證值，兩者是不一致的。通常應選擇抗拉強度保證值與母材相同或稍高的焊條。2）焊縫強度不是比母材高出愈多愈好，而應等于或稍高于母材。如果焊縫強度過高，往往使焊縫的塑性下降，反而有害。當焊接接頭不要求焊縫與其等強度時，可選用抗拉強度較低的焊條。（2）合金結(jié)構(gòu)鋼焊條的選用合金結(jié)構(gòu)鋼焊接時，通常均不要求焊縫金屬的合金成分與該鋼種的合金成分相同或相近，而主要考慮等強度。但如果母材是耐熱鋼、耐腐蝕鋼時，從保證焊接接頭的耐熱、耐腐蝕性能出發(fā)，則要求焊縫金屬的主要合金成分與母材相同或相近。此時，應根據(jù)母材的化學成分選用焊條。（3）根據(jù)母材抗裂性要求選用焊條母材成分中，如果含C或S，浙江模具焊絲供應商、P等雜質(zhì)較高時，浙江模具焊絲供應商，很容易在焊縫中形成裂紋，浙江模具焊絲供應商。焊劑為堿性系統(tǒng)的焊材可使熔填金屬獲得非常優(yōu)良的延性與韌性，但作業(yè)性遠較酸性系為差。浙江模具焊絲供應商</p><div

放射性氣溶膠是造成人體內(nèi)照射的主要威脅。強電弧光的危害焊接弧光輻射主要有可見光、紅外線和紫外線。它們作用到人體上，被人體組.織吸收，引起組.織的熱作用、光化學作用或電離作用，使人體組.織受到損傷。可見光線的光度比肉眼正常承受的光度大約大到一萬倍左右，當可見光線輻射人的眼睛時，會產(chǎn)生疼痛感，看不清東西，通常叫“晃眼”，在短時間內(nèi)失去勞動能力。紅外線對人體的危害主要是引起組.織的熱作用。在焊接過程中，眼部受到強烈的紅外線輻射，會立即感到強烈的灼傷和灼痛，發(fā)生閃光幻覺。長期接觸可能造成紅外線白內(nèi)障、視力減退，嚴重時可導致失明。紫外輻射(ultravioletradiation，UV)又稱紫外線，是指波長在100—400nm的電磁波。適量的紫外線照射可以對人體產(chǎn)生有益的作用，但是過量照射會對人體造成不良的影響(如電焊紫外輻射)。紫外線對人體的危害主要是光化學作用，對人體皮膚和眼睛造成損害。皮膚受到強烈的紫外線輻射后，可引起皮炎，彌漫性紅斑，有時出現(xiàn)小水泡、滲出液，有燒灼感，發(fā)癢；作用強烈時伴有全身癥狀：***、頭暈、易疲勞、神經(jīng)興奮、發(fā)燒、***等。紫外線過度照射人的眼睛，可引起眼睛急性角膜和結(jié)膜炎，即電光眼炎。焊絲溫度不會持續(xù)上升至其整段發(fā)紅，抗紅能力***。</p><div

1954年哈爾濱鍋爐廠從德國引進氬弧焊是在普通電弧焊的原理的基礎(chǔ)上,利用氬氣對金屬焊材的保護,通過高電流使焊材在被焊基材上熔化成液態(tài)形成熔池,使被焊金屬和焊材達到冶金結(jié)合的一種焊接技術(shù),由于在高溫熔融焊接中不斷送上氬氣,使焊材不能和空氣中的氧氣接觸,從而防止了焊材的氧化。手工鎢極氬弧焊時選擇電源的種類和極性的方法手工鎢極氬弧焊的電源有直流電源和交流電源,直流電源有直流正接法和直流反接法。直流正接法:焊件接正極,鎢極接負極,這樣焊接時,電子高速沖向焊件,焊接溫度高,熔池深而窄。正離子沖向鎢極,鎢極熱量低損耗小。該方法適用于耐熱鋼、合金鋼、不銹鋼、銅、鈦等金屬的焊接。直流反接法:焊件接負極,鎢極接正極,焊接時電子高速沖向鎢極,鎢極熱量高,消耗快,故一般不使用。用于焊接高熔點氧化膜的鋁、鎂及其合金。交流電源由于極**替變化,它既有“陰極霧化”作用,又有鎢極消耗比直流反接法少的特點,適用于鋁、鎂及其合金的焊接。手工鎢極氬弧焊時噴嘴的選擇方法噴嘴大小和形狀直接影響氬氣保護區(qū)的保護范圍和效果,常用的噴嘴有6號,7號,8號,10號。噴嘴直徑的選擇不宜過大,否則會妨礙操作,浪費氬氣;但也不宜過小,否則熔池保護不好,容易產(chǎn)生缺點。藥芯焊絲中的藥粉成分一般與焊條藥皮相似。南京H13焊絲訂購</p><p

兩種氣體同時存在比單一氣體的危害作用高15--20倍。防護措施（1）通風措施氬弧焊工作現(xiàn)場要有良好的通風裝置，以排出有害氣體及煙塵。除廠房通風外，可在焊接工作量大，焊機集中的地方，安裝幾臺軸流風機向外排風。此外，還可采用局部通風的措施將電弧周圍的有害氣體抽走，例如采用明弧排煙罩、排煙焊、輕便小風機等。（2）防護射線措施盡可能采用放射劑量極低的鈰鎢極。釷鎢極和鈰鎢極加工時，應采用密封式或抽風式砂輪磨削，操作者應配戴口罩、手套等個人防護用品，加工后要洗凈手臉。釷鎢極和鈰鎢極應放在鋁盒內(nèi)保存。（3）防護高頻的措施為了防備和削弱高頻電磁場的影響，采取的措施有：1）工件良好接地，焊電纜和地線要用金屬編織線屏蔽；2）適當降低頻率；3）盡量不要使用高頻振蕩器做為穩(wěn)弧裝置，減小高頻電作用時間。（4）其它個人防護措施氬弧焊時，由于臭氧和紫外線作用強烈，宜穿戴非棉布工作服（如耐酸呢、柞絲綢等）。在容器內(nèi)焊接又不能采用局部通風的情況下，可以采用送風式頭盔、送風口罩或防毒口罩等個人防護措施?！珰寤『副仨氉⒁獾膸讉€細節(jié)。。。1930年美國發(fā)明惰性氣體保護焊。浙江模具焊絲供應商</p><p
