A052不銹鋼焊條說明:A052是鈦鈣型藥皮的**碳Cr18Ni24Mo5不銹鋼焊條，其焊縫金屬具有耐含甲酸、醋酸介質(zhì)點腐蝕及抗氯離子腐蝕性能，它比A022等焊條耐腐蝕性能為優(yōu)。具有優(yōu)良的焊接工藝性能，可交直流兩用，江西H13焊絲供貨廠。用途:用于化學(xué)耐硫.酸、醋酸、磷酸的反應(yīng)器、分離器，同時可用于抗海水腐蝕用鋼（00Cr18Ni24Mo5）以及異種鋼的焊接。A062不銹鋼焊條符合GBE309L-16相當AWSE309L-16說明:A062是鈦鈣型藥皮的**碳Cr23Ni13不銹鋼焊條，可交直流兩用，由于含碳量低，故在不含Nb、Ti等穩(wěn)定劑時也能抵抗因碳化物析出而產(chǎn)生的晶間腐蝕。用途:用于合成纖維、石油化工等設(shè)備制造的相同類型的不銹鋼結(jié)構(gòu)，江西H13焊絲供貨廠、復(fù)合鋼和異種鋼等構(gòu)件，也可用于核反應(yīng)堆，江西H13焊絲供貨廠、壓力容器內(nèi)壁過渡層堆焊和塔內(nèi)構(gòu)件焊接。A101不銹鋼焊條符合GBE308-16相當AWSE308-16說明:A101是鈦型藥皮的Cr19Ni10不銹鋼焊條，可交直流兩用，施焊時藥皮具有不發(fā)紅、不開裂的特點，焊縫金屬具有良好的力學(xué)性能及抗晶間腐蝕性能，特別適宜于薄板平焊。用途:用于工作溫度低于300℃的Cr19Ni9及Cr19Ni11Ti的不銹鋼薄板結(jié)構(gòu)的焊接。特色A102不銹鋼焊條特色符合GBE308-16相當AWSE308-16說明:A102是鈦鈣型藥皮的Cr19Ni10不銹鋼焊條。藥芯焊絲中的藥粉成分一般與焊條藥皮相似。江西H13焊絲供貨廠</p><div

src="http://tyunfile.71360.com/UploadFile/shjianmin2/637179265671406250/559850.png"></div><p> 為防止底層焊道的背面被氧化，背面也需要實施氣體保護。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(yīng)保持80~85°角,填充焊絲與工件表面夾角應(yīng)盡可能地小，一般為10°左右。8、防風(fēng)與換氣。有風(fēng)的地方，務(wù)請采取擋網(wǎng)的措施，而在室內(nèi)則應(yīng)采取適當?shù)膿Q氣措施。二、不銹鋼焊接要點及注意事項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(fēng)。MIG焊接容易受到風(fēng)的影響，有時微風(fēng)而產(chǎn)生氣孔，所以風(fēng)速在，都應(yīng)當采取防風(fēng)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。江西H13焊絲供貨廠選擇具有熔化溫度低于母材的填充金屬，可**減小熱影響區(qū)中晶間裂紋傾向。</p><div

三)面罩及其它防護用具面罩的主要作用是保護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。面罩上的護目玻璃起到減弱電弧光并過濾紅外線、紫外線的作用。護目玻璃有不同色號、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目玻璃以保護視力。護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目玻璃。焊工用護目遮光鏡片的選用可按表11—8進行。其它防護用品有電焊工在工作時需佩帶的**電焊手套和護腳，以及清渣時應(yīng)戴的平光眼鏡。六、交流弧焊機與直流弧焊機的比較交流弧焊機的主要優(yōu)點是成本低、制造維護簡單，噪聲較小；缺點是不能適應(yīng)堿性焊條，且焊接電壓、電流容易受到電網(wǎng)波動的干擾。直流弧焊機的優(yōu)點是電弧穩(wěn)定，焊條適應(yīng)性強；缺點是成本較高，制造維修較復(fù)雜，重量較重。但由于優(yōu)點明顯，直流弧焊機是大有前途的電焊機。表3—7列出了兩類焊機的性能比較。</p><p> 圖3—10硅整流電弧焊機1—硅整流器組2—三相變壓器3—三相磁飽和電抗器4—輸出電抗器5—通風(fēng)機組(二)工作原理工作原理見圖3—11。接通開關(guān)K1，通風(fēng)機組FM運轉(zhuǎn)，風(fēng)壓開關(guān)KEY閉合，主接觸器Jc-1閉合，三相弧焊變壓器B1工作。與此同時Jc-2閉合，控制變壓器B2工作，磁放大器運行，硅整流器工作，輸出一定的直流電壓，這就是焊機的空載電壓。由于沒有焊接電流，磁放大器的電抗繞組FD電抗壓降幾乎為零，使焊機輸出端具有較高的空載電壓，便于引弧。當施焊時，由于有輸出，形成電流，電抗繞組FD通過交流電，使其得到較大的電抗壓降，并隨電流的增大，電抗壓降隨之增大，從而得到陡降外特性。當短路時，由于短路電流很大，F(xiàn)D通過的交流電急增，它產(chǎn)生的電抗壓降使工作電壓幾乎接近于零，這就限制了短路電流。圖3—11ZXG—300型硅整流電焊機電氣原理圖改變控制回路磁盤電阻R10，使磁放大器控制繞組FK中直流電發(fā)生變化，鐵芯中的磁通就相應(yīng)發(fā)生變化，從而改變了磁放大器交流繞組FD的電流。為減少網(wǎng)路電壓波動對焊接的影響，在控制回路中采用了鐵磁諧振式穩(wěn)壓器，以保證激磁電流的穩(wěn)定，減少對焊接電流的影響。按動K2，通風(fēng)機組FM停止工作，風(fēng)壓開關(guān)KEY開啟，主接觸器Jc-1斷開。請按焊絲的類別、規(guī)格分類存放、防止錯用。</p><div

style="text-indent:25px">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。江西H13焊絲供貨廠</p><p> 電感線圈的感抗電壓降使電焊機獲得較低的工作電壓，這是電焊機具有陡降外特性的原因。引弧時，電焊機能供給較高的電壓和較小的電流，當電弧穩(wěn)定燃燒時，電流增大，而電壓急劇降低；當焊條與工件短路時，也限制了短路電流。焊接電流調(diào)節(jié)分為粗調(diào)、細調(diào)兩檔。電流的細調(diào)靠移動鐵芯4改變變壓器的漏磁來實現(xiàn)。向外移動鐵芯，磁阻增大，漏磁減小，則電流增大，反之，則電流減少。電流的粗調(diào)靠改變次級繞組的匝數(shù)來實現(xiàn)。該電弧焊機的工作條件為應(yīng)在海拔不超過1000m，周圍空氣溫度不超過+40℃、空氣相對濕度不超過85％等條件下使用，不應(yīng)在有害工業(yè)氣體、水蒸汽、易燃、多灰塵的場合下工作。二、直流弧焊機(一)結(jié)構(gòu)由于整流或直流弧焊機與直流弧焊發(fā)電機比較，因沒有機械旋轉(zhuǎn)部分，具有噪音小，空載損耗小、效率高、成本低和制造維護簡單等優(yōu)點。因此，有取代直流弧焊發(fā)電機的趨勢，在這里只介紹整流式直流弧焊機。整流式直流弧焊機常用型號如ZXG—300、ZXG—400等。硅整流電弧焊機是利用硅半導(dǎo)體整流元件(二極管)將交流電變?yōu)橹绷麟娮鳛楹附与娫?。圖3—10為硅整流電弧焊機的結(jié)構(gòu)示意圖。江西H13焊絲供貨廠</p><p
