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。化學(xué)清洗分為兩種類型：浸漬法和擦洗法，清潔劑和清潔過(guò)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(cè)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(duì)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(shí)，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="河南電子點(diǎn)焊機(jī)" src="http://tyunfile.71360.com/UpLoadFile/suzhouanjia/2020/1/637140711437070354/6371407114370703549033763.jpg"></div><p> 中頻點(diǎn)焊機(jī)的技術(shù)優(yōu)勢(shì) </p> <p> 1、焊接質(zhì)量 </p> <p> 工頻交流焊機(jī)的調(diào)節(jié)周期較長(zhǎng)，對(duì)50Hz的電網(wǎng)，焊接時(shí)間調(diào)節(jié)分辨率為20ms。逆變直流點(diǎn)焊機(jī)時(shí)間調(diào)節(jié)分辨率可達(dá)0.25ms(4kHz逆變頻率)，控制精度高。逆變焊機(jī)的反饋控制的響應(yīng)速度明顯加快，輸出穩(wěn)定性好。 </p> <p> 工頻交流焊機(jī)由于電流過(guò)零的影響，熱效率低，用晶閘管調(diào)節(jié)電流，當(dāng)電流百分比偏小時(shí)，過(guò)零時(shí)間長(zhǎng)，影響更大；逆變直流點(diǎn)焊機(jī)輸出電流為脈動(dòng)直流，在回路電感的作用下為連續(xù)直流輸出，熱效率高，焊接熱輸入穩(wěn)定。 </p> <p> 2、焊接速度 </p> <p> 工頻交流焊機(jī)由于電流過(guò)零的影響，加熱時(shí)間相對(duì)較長(zhǎng)。逆變電阻點(diǎn)焊機(jī)為直流輸出，加熱集中，焊接時(shí)間縮短。 </p> <p> 3、節(jié)能效果 </p> <p> 工頻交流點(diǎn)焊機(jī)工作在50Hz，變壓器損耗大，焊機(jī)功率因素低，回路損耗大。逆變焊機(jī)變壓器工作在較高的頻率(1-4kHz)，損耗很小，直流輸出改善功率因素，節(jié)能效果明顯。 </p> <p> 4、設(shè)備體積與重量 </p> <p> 工頻交流焊機(jī)的變壓器鐵心較大，同樣功率條件下設(shè)備較笨重。逆變直流電阻點(diǎn)焊機(jī)變壓器大大減小，設(shè)備較輕巧 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="河南電子點(diǎn)焊機(jī)"
