style="text-indent:25px">焊接通過(guò)下列三種途徑達(dá)成接合的目的：熔焊加熱欲接合之工件使之局部熔化形成熔池，熔池冷卻凝固后便接合，必要時(shí)可加入熔填物輔助，它是適合各種金屬和合金的焊接加工，不需壓力。壓焊焊接過(guò)程必須對(duì)焊件施加壓力，屬于各種金屬材料和部分金屬材料的加工。釬焊采用比母材熔點(diǎn)低的金屬材料做釬料，利用液態(tài)釬料潤(rùn)濕母材，填充接頭間隙，并與母材互相擴(kuò)散實(shí)現(xiàn)鏈接焊件。適合于各種材料的焊接加工，也適合于不同金屬或異類材料的焊接加工。焊接過(guò)程中，工件和焊料熔化形成熔融區(qū)域，熔池冷卻凝固后便形成材料之間的連接。這一過(guò)程中，通常還需要施加壓力。焊接的能量來(lái)源有很多種，包括氣體焰、電弧、激光、電子束、摩擦和超聲波等。焊接工藝是鐵匠沿用了數(shù)百年的金屬鍛焊。隨著焊接機(jī)器人在工業(yè)應(yīng)用中的應(yīng)用，研究人員仍在深入研究焊接的本質(zhì)，繼續(xù)開(kāi)發(fā)新的焊接方法，以進(jìn)一步提高焊接質(zhì)量。松江區(qū)焊接工廠自動(dòng)焊接通過(guò)自動(dòng)送絲裝置來(lái)保證電弧的連貫性。</p><div

Mo系焊絲。不銹鋼焊接時(shí)，采用的焊絲成分要與被焊接的不銹鋼成分基本一致。焊接鉻不銹鋼時(shí)可采用焊絲，焊接鉻鎳不銹鋼時(shí)，可采用焊絲；焊接較低碳不銹鋼時(shí)，應(yīng)采用相應(yīng)的較低碳焊絲，焊劑可采用熔煉型或燒結(jié)型，要求焊劑的氧化性要小，以減少合金元素的燒損。焊條電弧焊：原理用手工操作焊條進(jìn)行焊接的電弧焊方法。利用焊條與焊件之間建立起來(lái)的穩(wěn)定燃燒的電弧，使焊條和焊件熔化，從而獲得牢固的焊接接頭。屬氣－渣聯(lián)合保護(hù)。主要特點(diǎn)操作靈活；待焊接頭裝配要求低；可焊金屬材料廣；焊接生產(chǎn)率低；焊縫質(zhì)量依賴性強(qiáng)（依賴于焊工的操作技能及現(xiàn)場(chǎng)發(fā)揮）。應(yīng)用于造船、鍋爐及壓力容器、機(jī)械制造、建筑結(jié)構(gòu)、化工設(shè)備等制造維修行業(yè)中。適用于（上述行業(yè)中）各種金屬材料、各種厚度、各種結(jié)構(gòu)形狀的焊接。焊接給人體可能造成的傷害包括燒傷、觸電、視力損害、吸入有毒氣體、紫外線照射過(guò)度等。</p><div

style="text-indent:25px">工件的預(yù)熱、層間溫度影響：預(yù)熱溫度和層間溫度越高，相當(dāng)于熱輸入增大，使冷卻速度減慢，收縮變形增大。焊接方法的影響：在建筑鋼結(jié)構(gòu)焊接常用的幾種方法中，除電渣焊以外，埋弧焊熱輸入較大，在其他條件如焊縫面積等相同情況下，收縮變形較大。手工電弧焊熱輸入居中，收縮變形比埋弧焊小。CO2氣體保護(hù)焊熱輸入較小，收縮變形響應(yīng)也較小。焊縫位置對(duì)變形的影響：由于焊縫位置在結(jié)構(gòu)中不對(duì)稱，焊縫位置不對(duì)稱等將引起各種變形。結(jié)構(gòu)的剛性對(duì)焊接變形的影響：結(jié)構(gòu)的剛性大小，主要取決于結(jié)構(gòu)的形狀和其截面大小，剛性較小的結(jié)構(gòu)，焊接變形大；剛性大的結(jié)構(gòu)，焊后變形較小。裝配和焊接規(guī)范對(duì)焊接變形的影響：由于采取的裝配方法不同，對(duì)結(jié)構(gòu)的變形也有影響。整體裝配完再進(jìn)行焊接，其變形一般小于邊裝配邊焊接。焊接時(shí)形成的連接兩個(gè)被連接體的接縫稱為焊縫。松江區(qū)焊接工廠</p><p
