電弧周圍形成多種有害氣體，其中主要有臭氧、氮氧化物、一氧化碳和氟化氫等。臭氧是一種刺激性氣體，呈淡藍色。濃度較高時，發(fā)出腥臭味；高濃度臭氧還略帶酸味。臭氧對人體的主要危害是對呼吸道及肺有強烈刺激作用。往往引起咳嗽、胸悶、食欲不振、疲勞無力、頭暈、全身疼痛等，嚴重時還會引起***和肺水腫等。氮氧化物是刺激性氣體。二氧化氮呈紅褐色，具有特殊臭味。氮氧化物對人體的危害主要是對肺組.織的刺激作用。其被吸人呼吸道后，在肺泡內(nèi)逐漸與水作用形成硝酸和亞硝酸，對肺組.織產(chǎn)生強烈刺激和腐蝕作用，引起中毒。慢性中毒的主要癥狀是神經(jīng)衰弱，如***、***、食欲不振、體重下降。濃度高的氮氧化物能引起急性中毒，其中毒輕者，*發(fā)生急性***；重度中毒時，引發(fā)咳嗽激烈、呼吸困難、虛脫、全身軟弱無力等癥狀。氮氧化物對人體的作用也是可逆的，隨著脫離作業(yè)時間的增長，其不良影響逐漸減少或消除。在鎢極氬弧焊時，如果不采取通風措施，其濃度往往超過衛(wèi)生標準十幾倍，甚至幾十倍。我國規(guī)定的氮氧化物(換算成二氧化氮)的衛(wèi)生標準為5mg／m3。在焊接過程中，通常臭氧和氮氧化物同時存在，因此它們的毒性更大。一般情況下。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

第三節(jié)焊條電弧焊與電弧切割設(shè)備的基本結(jié)構(gòu)和工作原理圖3—6焊機分類焊條電弧焊所用焊機按電源的種類可分為交流弧焊機和直流弧焊機兩大類。其中直流弧焊機按變流的方式不同又分為：弧焊整流器、逆變弧焊機和旋轉(zhuǎn)式直流弧焊發(fā)電機(現(xiàn)已淘汰)等。每一類型的焊機根據(jù)原理和結(jié)構(gòu)特點又可分為多種型式，具體見圖3—6一、交流弧焊機(一)結(jié)構(gòu)交流弧焊機的三個類別的結(jié)構(gòu)分別如圖3—7～圖3—9所示。圖3—7BX1—330交流弧焊機1—初級繞組；2、3—次級繞組；4—動鐵芯；5—靜鐵芯；6—接線板；7—搖把圖3—8BX2—500型(同體式)焊機結(jié)構(gòu)示意圖1—固定鐵心2—初級繞組3—次級繞組4—電抗線圈5—活動鐵心圖3—9BX3—300型(動圈式)焊機結(jié)構(gòu)示意圖1—初級線圈2—次級線圈3—鐵心(二)工作原理目前應用*****的“動鐵式”交流焊機如圖3—7所示。它是一個結(jié)構(gòu)特殊的降壓變壓器，屬于動鐵芯漏磁式類型。焊機的空載電壓為60～70V。工作電壓為30V，電流調(diào)節(jié)范圍為50～450A。鐵芯由兩側(cè)的靜鐵芯5和中間的動鐵芯4組成，變壓器的次級繞組分成兩部分，一部分緊繞在初級繞組1的外部，另一部分繞在鐵芯的另一側(cè)。前一部分起建立電壓的作用，后一部分相當于電感線圈。焊接時。在埋弧焊、電渣焊和其他熔化極氣體保護電弧焊時，焊絲既是填充金屬，同時焊絲也是導電電極。山東H13焊絲供貨廠</p><p

7、為使氬氣很好地保護焊接熔池，和便于施焊操作，鎢極中心線與焊接處工件一般應保持80~85°角,填充焊絲與工件表面夾角應盡可能地小，一般為10°左右。8、防風與換氣。有風的地方，務請采取擋網(wǎng)的措施，而在室內(nèi)則應采取適當?shù)膿Q氣措施。二、不銹鋼MIG焊要點及注意事項1、采用平特性焊接電源，直流時采用反極性(焊絲接正極)2、一般采用純氬氣(純度為)或Ar+2%O2,流量以20~25L/min為宜。3、電弧長度，不銹鋼的MIG焊接，一般都在噴射過渡的條件下來施焊，電壓要調(diào)整到弧長在4~6mm的程度。4、防風。MIG焊接容易受到風的影響，有時微風而產(chǎn)生氣孔，所以風速在，都應當采取防風措施。三、不銹鋼藥芯焊絲焊接要點及注意事項1、采用平特性焊接電源，直流焊接時采用反極性。使用一般的CO2焊機就可以施焊，但送絲輪的壓力請稍調(diào)松。2、保護氣體一般為二氧化碳氣體，氣體流量以20~25L/min較適宜。3、焊嘴與工件間的距離以15~25mm為宜。4、干伸長度，一般的焊接電流為250A以下時約15mm，250A以上時約20~25mm較為合適?！珰寤『笇θ梭w有多大危害？一定要重視！焊接技術(shù)氬弧焊的危害程度要比焊條電弧焊相對來說要大，但是沒有大到讓人望而生畏的地步。江西RD12M焊絲訂購</p><p
