1954年哈爾濱鍋爐廠從德國引進(jìn)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(hù),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(dá)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(fù)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(fù)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(diǎn)氧化膜的鋁、鎂及其合金。交流電源由于極**替變化，昆山模具焊絲批發(fā),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(diǎn),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(hù)區(qū)的保護(hù)范圍和效果，昆山模具焊絲批發(fā),常用的噴嘴有6號，昆山模具焊絲批發(fā),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(fèi)氬氣;但也不宜過小,否則熔池保護(hù)不好,容易產(chǎn)生缺點(diǎn)。藥芯焊絲是很有發(fā)展前途的新型焊接材料，國產(chǎn)藥芯焊絲的品種和用量與日俱增。昆山模具焊絲批發(fā)</p><div

按適用范圍不同，可分為斜三角形和正三角形兩種運(yùn)條方法。其中斜三角形運(yùn)條法適用于焊接T形接頭的仰焊縫和有坡口的橫焊縫。其特點(diǎn)是能夠通過焊條的擺動控制熔化金屬，促使焊縫成形良好。正三角形運(yùn)條法*適用于開坡口的對接接頭和T形接頭的立焊。其特點(diǎn)是一次能焊出較厚的焊縫斷面，有利于提高生產(chǎn)率，而且焊縫不易產(chǎn)生夾渣等缺點(diǎn)。三角形運(yùn)條法6)圓圈形運(yùn)條法。如圖3—22所示，將焊條末端連續(xù)作圓圈運(yùn)動，并不斷前進(jìn)。這種運(yùn)條方法又分正圓圈和斜圓圈兩種。正圓圈運(yùn)條法只適于焊接較厚工件的平焊縫，其優(yōu)點(diǎn)是能使熔化金屬有足夠高的溫度，有利于氣體從熔池中逸出，可防止焊縫產(chǎn)生氣孔。斜圓圈運(yùn)條法適用于T形接頭的橫焊(平角焊)和仰焊以及對接接頭的橫焊縫，其特點(diǎn)是可控制熔化金屬不受重力影響，能防止金屬液體下淌，有助于焊縫成形。圓圈形運(yùn)條法(三)收尾電弧中斷和焊接結(jié)束時，應(yīng)把收尾處的弧坑填滿。若收尾時立即拉斷電弧，則會形成比焊件表面低的弧坑。在弧坑處常出現(xiàn)疏松、裂紋、氣孔、夾渣等現(xiàn)象，因此焊縫完成時的收尾動作不*是熄滅電弧，而且要填滿弧坑。收尾動作有以下幾種：(1)劃圈收尾法。焊條移至焊縫終點(diǎn)時，作圓圈運(yùn)動，直到填滿弧坑再拉斷電弧。昆山模具焊絲批發(fā)焊絲應(yīng)放在木托盤上，不能將其直接放在地板或緊貼墻壁。</p><div

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(qiáng)度，此時可按結(jié)構(gòu)鋼的強(qiáng)度選擇相應(yīng)強(qiáng)度等級的焊條。選擇時應(yīng)注意以下兩點(diǎn)：1）鋼材的強(qiáng)度等級是按屈服點(diǎn)劃分的，而結(jié)構(gòu)鋼焊條的強(qiáng)度等級系指其抗拉強(qiáng)度的比較低保證值，兩者是不一致的。通常應(yīng)選擇抗拉強(qiáng)度保證值與母材相同或稍高的焊條。2）焊縫強(qiáng)度不是比母材高出愈多愈好，而應(yīng)等于或稍高于母材。如果焊縫強(qiáng)度過高，往往使焊縫的塑性下降，反而有害。當(dāng)焊接接頭不要求焊縫與其等強(qiáng)度時，可選用抗拉強(qiáng)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(qiáng)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(yīng)根據(jù)母材的化學(xué)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、P等雜質(zhì)較高時，很容易在焊縫中形成裂紋。</p><p>
