中頻點(diǎn)焊機(jī)焊接產(chǎn)品的時候，會出現(xiàn)電流分流的情況，出現(xiàn)分流的原因有兩種：<span style="font-size:12px;">1、點(diǎn)焊機(jī)焊點(diǎn)強(qiáng)度降低。</span><span style="font-size:12px;">2、單面點(diǎn)焊產(chǎn)生局部接觸表面過熱和噴濺。</span> </p> <p> <span style="font-size:12px;">那么電流分流的都帶來哪些不良影響呢？</span> </p> <p> 1點(diǎn)焊機(jī)焊點(diǎn)強(qiáng)度降低 </p> <p> 點(diǎn)距過小引起的分流使焊接區(qū)的電流密度減小因而加熱不足，熔核直徑和焊透率隨之降低，焊點(diǎn)承載能力下降，嚴(yán)重時產(chǎn)生未焊透。同時由于形成分流的偶然因素很多，分流數(shù)值很大穩(wěn)定，安徽焊鋁點(diǎn)焊機(jī)，因而又造成焊點(diǎn)質(zhì)量波動很大。 </p> <p> 2單面點(diǎn)焊產(chǎn)生局部接觸表面過熱和噴濺單面點(diǎn)焊由于分流嚴(yán)重會使電極與工件局部接觸面過熱，甚至熔化，嚴(yán)重時形成初期表面噴濺，同時，安徽焊鋁點(diǎn)焊機(jī)，分流還會引起熔核歪斜，并溢出焊件表面而形成晚期噴濺。初期表面噴濺在單面多點(diǎn)焊時尤為嚴(yán)重，它不僅惡化了勞動條件，安徽焊鋁點(diǎn)焊機(jī)，增加電極磨損，而且為了去除噴濺遺留下的毛刺，常常不得不增加一道令人厭煩的打磨毛刺工序。

style="text-indent:25px">選購點(diǎn)焊機(jī)的標(biāo)準(zhǔn)是什么確定被焊工件是黑色金屬，一般選用交流點(diǎn)焊機(jī)。因?yàn)榻涣鼽c(diǎn)焊機(jī)是采用交流電放電焊接，特別適合電阻值較大的材料，同時交流點(diǎn)焊機(jī)可通過運(yùn)用單脈沖，多脈沖信號、周波、時間、電壓、電流、程序各項(xiàng)控制方法，對被焊工件實(shí)施單點(diǎn)、雙點(diǎn)連續(xù)、自動控制、人為控制焊接。適用于鎢，鉬，鐵，鎳，不銹鋼等多種金屬的片，棒，絲料的焊接。其缺點(diǎn)是： 1、受電網(wǎng)電壓波動影響較大，即交流點(diǎn)焊機(jī)焊接電流會隨電網(wǎng)電壓波動而波動，從而影響焊接的一致性。2、交流點(diǎn)焊機(jī)焊接放電**短通常為1/2周波即0.01秒，不適合一些特殊合金材料的高標(biāo)準(zhǔn)焊接。其優(yōu)點(diǎn)是： 1、綜合效益好性價比較高。 2、焊接條件范圍大。 3、焊接回路小型輕量化。 4、可以***點(diǎn)焊異種金屬。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="安徽焊鋁點(diǎn)焊機(jī)"

style="font-size:12px;">1.焊前清潔</span> </p> <p> 清潔的目的是去除焊件表面的氧化膜和油污，這是防止產(chǎn)生氣孔和夾雜物的重要措施。 </p> <p> 1）化學(xué)清洗。高效，穩(wěn)定的質(zhì)量，適用于小線徑和批量生產(chǎn)的焊件清洗?；瘜W(xué)清洗分為兩種類型：浸漬法和擦洗法，清潔劑和清潔過程。 </p> <p> 2）機(jī)械清潔。用有機(jī)溶劑（**，松香或汽油）擦拭焊件表面的油，然后用細(xì)銅線刷涂以露出表面，或用刮刀清潔表面。清潔后的焊件應(yīng)在4h內(nèi)焊接，否則應(yīng)再次清洗。 </p> <p> 2.背板 </p> <p> 為了確保穿透并防止焊接件焊接或塌陷，可以在焊接之前將背板放置在接頭下方。墊的材料可以是石墨，非標(biāo)訂制焊接測試設(shè)備不銹鋼或碳鋼，并且在表面上形成圓弧槽以確保形成反向焊接。 </p> <p> 3.預(yù)熱 </p> <p> 對于薄型和小型焊件，通常不需要預(yù)熱。焊接厚度大于5 mm的焊件時，為了達(dá)到接頭附近所需的溫度，焊接前應(yīng)預(yù)熱焊件，預(yù)熱溫度為100-300°C。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="安徽焊鋁點(diǎn)焊機(jī)"
