焊條電弧焊從焊接電弧的基礎(chǔ)講起，按“有認(rèn)知、易學(xué)會(huì)、好掌握、能操作”的原則，由淺入深、循序漸進(jìn)地講解了焊條電弧焊的工藝?yán)碚摵蛯?shí)操技能。本書主要內(nèi)容包括：焊接技術(shù)基礎(chǔ)知識(shí)、焊條電弧焊設(shè)備、焊條的組成和分類、焊條的型號(hào)與牌號(hào)、常用焊條焊接工藝性能及選用原則、焊條的正確保管與貯存、焊條電弧焊基本工藝知識(shí)、焊接冶金基本知識(shí)、焊接接頭的組.織與性能、焊條電弧焊常見(jiàn)焊接缺點(diǎn)及其防止、典型管類和管板類焊接技術(shù)、碳弧氣刨。一、焊條電弧焊的操作焊條電弧焊**基本的操作是引弧、運(yùn)條和收尾(一)引弧引弧即產(chǎn)生電弧。焊條電弧焊是采用低電壓、大電流放電產(chǎn)生電弧，依靠電焊條瞬時(shí)接觸工件實(shí)現(xiàn)。引弧時(shí)必須將焊條末端與焊件表面接觸形成短路，然后迅速將焊條向上提起2～4mm的距離，此時(shí)電弧即引燃。引弧的方法有兩種：碰擊法和擦劃法，詳見(jiàn)圖3—14引弧方法(1)碰擊法。也稱點(diǎn)接觸法或稱敲擊法。碰擊法是將焊條與工件保持一定距離，然后垂直落下，使之輕輕敲擊工件，發(fā)生短路，再迅速將焊條提起，產(chǎn)生電弧的引弧方法，山東激光焊絲工廠。此種方法適用于各種位置的焊接。(2)擦劃法。也稱線接觸法或稱摩擦法。擦劃法是將電焊條在坡口上滑動(dòng)，成一條線，山東激光焊絲工廠，當(dāng)端部接觸時(shí)，山東激光焊絲工廠，發(fā)生短路。焊接時(shí)，送絲較實(shí)心焊絲困難。山東激光焊絲工廠</p><div

本實(shí)用新型涉及一種用于制造防腐罐焊條的自動(dòng)生產(chǎn)線。背景技術(shù)：防腐罐本體為pph聚丙烯材質(zhì)，采用pph聚丙烯的焊條焊接成型，焊條橫截面為等邊三角形。防腐罐焊條通過(guò)塑料擠出機(jī)制作，焊條經(jīng)塑料擠出機(jī)成型后再人工剪切成條。但是塑料擠出機(jī)出來(lái)的焊條溫度較高，人工剪切不便于握持，且對(duì)尚未降溫的焊條進(jìn)行剪切易造成焊條變形；但若不及時(shí)進(jìn)行剪切，源源不斷出來(lái)的焊條又無(wú)處放置。技術(shù)實(shí)現(xiàn)要素：本實(shí)用新型旨在提供一種防腐罐焊條的自動(dòng)生產(chǎn)線，能對(duì)塑料擠出機(jī)出來(lái)的pph聚丙烯焊條進(jìn)行及時(shí)冷卻及自動(dòng)剪切成條，并確保焊條質(zhì)量。為此，本實(shí)用新型所采用的技術(shù)方案為：一種防腐罐用焊條自動(dòng)生產(chǎn)設(shè)備，包括塑料擠出機(jī)，還包括水冷循環(huán)系統(tǒng)和自動(dòng)切斷機(jī)構(gòu)，三者從前到后依次布置；所述水冷循環(huán)系統(tǒng)包括機(jī)架，所述機(jī)架上方設(shè)置有長(zhǎng)條形的水槽，所述水槽由水平隔板分割成敞開的上層槽和封閉的下層槽，在水槽的兩端設(shè)置有連通槽，所述上層槽的前壁、后壁上對(duì)應(yīng)開設(shè)有焊條過(guò)孔，且焊條過(guò)孔的直徑為等邊三角形焊條邊長(zhǎng)的兩倍到三倍之間，在上層槽內(nèi)前后間隔安裝有至少兩根水平設(shè)置的焊條導(dǎo)向桿，且焊條過(guò)孔、焊條導(dǎo)向桿在高度上齊平，所述上層槽的冷卻水能經(jīng)焊條過(guò)孔流入連通槽。山東激光焊絲工廠需要彎曲加工的焊接接頭，一般加工性受塑性的影響，而塑性隨著強(qiáng)度的增大而降低。</p><div

1、焊接方法板狀仰焊的焊接有2種方法：連弧法及熄弧法。連弧法是通過(guò)連續(xù)而有規(guī)則地?cái)[動(dòng)焊條進(jìn)行短弧施焊的操作方法；熄弧法是在封底焊時(shí)采用電弧燃燒一定時(shí)即行熄滅，然后再引燃、再熄滅，從而使熔池金屬迭加成形的方法。這2種方法各有所長(zhǎng)。熄弧法可以保證封底焊縫有良好的成形，能有效地控制焊縫下垂、頂面內(nèi)凹，缺點(diǎn)是由于焊接過(guò)程處于間斷狀態(tài)，容易出現(xiàn)氣孔、夾渣等缺點(diǎn)。連弧法可以使焊接過(guò)程連續(xù)化，能夠有效地保證焊接質(zhì)量，但操作方法不當(dāng)將會(huì)造成焊縫下垂，表面內(nèi)凹。比較2種焊接方法，連弧焊更值得推廣。在一些工業(yè)發(fā)達(dá)國(guó)家，如德國(guó)、美國(guó)、日本等，生產(chǎn)中都要求采用這種焊接方法。2試板及工藝要求試板要求試板材質(zhì)為Q235B，規(guī)格為100mm×12mm×300mm。采用E5015（J507）焊條，焊接位置為仰焊，要求單面焊雙面成形。坡口形式如圖1所示。焊接工藝參數(shù)焊接工藝參數(shù)見(jiàn)表1。表1焊接工藝參數(shù)焊條角度施焊過(guò)程中焊條與焊接方向的夾角如圖2所示。3、焊接操作要點(diǎn)封底層的焊接對(duì)整個(gè)試板而言，封底層的焊接是關(guān)鍵，在焊接過(guò)程中，焊接熔池金屬的自身重力在電弧作用力和液態(tài)金屬的表面張力作用下處于平衡狀態(tài)。具體操作是地。</p><p> 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(chǎng)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(tái)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(chǎng)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(guó)發(fā)明惰性氣體保護(hù)焊。焊絲焊補(bǔ)時(shí)熱影響區(qū)非常小，不會(huì)產(chǎn)生內(nèi)應(yīng)力。</p><div

7、為使氬氣很好地保護(hù)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(qǐng)采取擋網(wǎng)的措施，而在室內(nèi)則應(yīng)采取適當(dāng)?shù)膿Q氣措施。二、不銹鋼MIG焊要點(diǎn)及注意事項(xiàng)1、采用平特性焊接電源，直流時(shí)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(zhǎng)度，不銹鋼的MIG焊接，一般都在噴射過(guò)渡的條件下來(lái)施焊，電壓要調(diào)整到弧長(zhǎng)在4~6mm的程度。4、防風(fēng)。MIG焊接容易受到風(fēng)的影響，有時(shí)微風(fēng)而產(chǎn)生氣孔，所以風(fēng)速在，都應(yīng)當(dāng)采取防風(fēng)措施。三、不銹鋼藥芯焊絲焊接要點(diǎn)及注意事項(xiàng)1、采用平特性焊接電源，直流焊接時(shí)采用反極性。使用一般的CO2焊機(jī)就可以施焊，但送絲輪的壓力請(qǐng)稍調(diào)松。2、保護(hù)氣體一般為二氧化碳?xì)怏w，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(zhǎng)度，一般的焊接電流為250A以下時(shí)約15mm，250A以上時(shí)約20~25mm較為合適。～～～～～～～～～～～～～～氬弧焊對(duì)人體有多大危害？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(duì)來(lái)說(shuō)要大，但是沒(méi)有大到讓人望而生畏的地步。鉬、鉻、碳、錳、鎳及釩等合金元素的添加，可以提高（改善）熔填金屬的強(qiáng)度、延性、硬度及韌性等。浙江GZ60S焊絲銷售</p><p
