style="text-indent:25px">中頻點焊機焊接過程當(dāng)中偶爾會遇到點焊虛焊等現(xiàn)象，虛焊也屬于焊接缺點的一種，由于焊接接頭的不完整性稱為焊接缺欠，主要以裂紋、虛焊、固體加雜、未熔合、未焊透、形狀缺點等。這些缺點減少焊縫截面積，降低承載能力，上海鍍鋅板**點焊機，產(chǎn)生應(yīng)力集中，引起裂紋；降低疲勞強度，易引起焊件破裂導(dǎo)致脆斷，這樣會嚴(yán)重影響焊接美觀及質(zhì)量，加強焊接工藝及手段是避免缺點的主要途徑。虛焊是最常見的一種缺點，有時在焊接以后看上去似乎將前后的鋼帶焊在一起，但實際上沒有達到融為一體的程度，結(jié)合面的強度很低，焊縫在生產(chǎn)線上要經(jīng)過各種復(fù)雜的工藝過程，上海鍍鋅板**點焊機，上海鍍鋅板**點焊機，特別是要經(jīng)過高溫的爐區(qū)和高張力的拉矯區(qū)，所以虛焊的焊縫在生產(chǎn)線上記憶造成斷帶事故，給生產(chǎn)線正常運行帶來很大的影響。</p><div

style="text-indent:25px">點焊機工作原理：點焊的工藝過程為開通冷卻水;將焊件表面清理干凈，裝配準(zhǔn)確后，送入上、下電極之間，施加壓力，使其接觸良好;通電使兩工件接觸表面受熱，局部熔化，形成熔核;斷電后保持壓力，使熔核在壓力下冷卻凝固　形成焊點;去除壓力，取出工件。焊接電流、電極壓力、通電時間及電極工作表面尺寸等點焊工藝參數(shù)對焊接質(zhì)量有重大影響。點焊機利用正負兩極在瞬間短路時產(chǎn)生的高溫電弧來熔化電極間的被焊材料，來達到使它們結(jié)合的目的。點焊機的結(jié)構(gòu)十分簡單，說白了就是一個大功率的變壓器，將220V交流電變?yōu)榈碗妷?，大電流的電源，可以是直流的也可以是交流的。電焊變壓器有自身的特點，就是具有電壓急劇下降的特性。在焊條引燃后電壓下降，電焊機的工作電壓的調(diào)節(jié)，除了一次的220/380電壓變換，二次線圈也有抽頭變換電壓，同時還有用鐵芯來調(diào)節(jié)的，可調(diào)鐵芯。電焊機一般是一個大功率的變壓器，系利用電感的原理做成的。電感量在接通和斷開時會產(chǎn)生巨大的電壓變化，利用正負兩極在瞬間短路時產(chǎn)生的高壓電弧來熔化電焊條上的焊料。來達到使它們結(jié)合的目的。</p><div
