手工鎢極氬弧工藝特點(diǎn)工作原理鎢極氬弧焊是采用鎢棒作為電極，利用氬氣作為保護(hù)氣體進(jìn)行焊接的一種氣體保護(hù)焊方法。通過鎢極與工件之間產(chǎn)生電弧，利用從焊噴嘴中噴出的氬氣流在電弧區(qū)形成嚴(yán)密封閉的氣層，使電極和金屬熔池與空氣隔離，以防止空氣的侵入。同時(shí)利用電弧熱來熔化基本金屬和填充焊絲形成熔池。液態(tài)金屬熔池凝固后形成焊縫。由于氬氣是一種惰性氣體，不與金屬起化學(xué)反應(yīng)，所以能充分保護(hù)金屬熔池不被氧化。同時(shí)氬氣在高溫時(shí)不溶于液態(tài)金屬中，所以焊縫不易生成氣孔。因此，氬氣的保護(hù)作用是有效和可靠的，可以獲得較高質(zhì)量的焊縫。焊接時(shí)鎢極不熔化，所以鎢極氬弧焊又稱為非熔化極氬弧焊。根據(jù)所采用的電源種類，鎢極氬弧焊又分為直流、交流和脈沖三種。焊不銹鋼用什么焊條？不銹鋼怎么焊接？焊接技術(shù)焊接是被焊工件的材質(zhì)（同種或異種），通過加熱或加壓或兩者并用，并且用或不用填充材料，使工件的材質(zhì)達(dá)到原子間的結(jié)合而形成長久性連接的工藝過程。那么不銹鋼焊接要點(diǎn)與注意事項(xiàng)有哪些要點(diǎn)呢？焊不銹鋼用什么焊條不銹鋼焊條可分為鉻不銹鋼焊條和鉻鎳不銹鋼焊條，這兩類焊條中凡符合國標(biāo)的，均按國標(biāo)GB/T983-2012規(guī)定考核。鉻不銹鋼具有一定的耐蝕。</p><p> 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(shí)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(shí)采用中性火焰，以免工件表面氧化。而焊接時(shí)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(shí)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(dòng)，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(dòng)，不作橫向擺動(dòng)。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）。藥芯焊絲可用于碳鋼，低合金高張力鋼，**度淬火回火鋼，不銹鋼以及硬面耐磨鋼材等的焊接。</p><div

兩種氣體同時(shí)存在比單一氣體的危害作用高15--20倍。防護(hù)措施（1）通風(fēng)措施氬弧焊工作現(xiàn)場要有良好的通風(fēng)裝置，以排出有害氣體及煙塵。除廠房通風(fēng)外，可在焊接工作量大，焊機(jī)集中的地方，安裝幾臺軸流風(fēng)機(jī)向外排風(fēng)。此外，還可采用局部通風(fēng)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(fēng)機(jī)等。（2）防護(hù)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(shí)，應(yīng)采用密封式或抽風(fēng)式砂輪磨削，操作者應(yīng)配戴口罩、手套等個(gè)人防護(hù)用品，加工后要洗凈手臉。釷鎢極和鈰鎢極應(yīng)放在鋁盒內(nèi)保存。（3）防護(hù)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(dāng)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(shí)間。（4）其它個(gè)人防護(hù)措施氬弧焊時(shí)，由于臭氧和紫外線作用強(qiáng)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(fēng)的情況下，可以采用送風(fēng)式頭盔、送風(fēng)口罩或防毒口罩等個(gè)人防護(hù)措施。～～～～～～～～～～～～氬弧焊必須注意的幾個(gè)細(xì)節(jié)。。。1930年美國發(fā)明惰性氣體保護(hù)焊。實(shí)芯焊絲的分類及特點(diǎn)
