電容儲(chǔ)能點(diǎn)焊機(jī)點(diǎn)焊的缺陷有哪些?

電容儲(chǔ)能點(diǎn)焊機(jī)點(diǎn)焊的焊點(diǎn)如果質(zhì)量良好,無(wú)論從外觀還是從焊核內(nèi)部都是沒(méi)有缺陷的。從外觀看,焊點(diǎn)是表面平整,無(wú)燒傷、壓痕深等各種缺陷。從內(nèi)部看,應(yīng)有尺寸合適的焊核,焊核應(yīng)是很致密的鑄造組織,核內(nèi)不能有縮孔、疏松、裂紋等缺陷。

If the quality of the spot welded joints of the capacitor energy storage spot welding machine is good, there are no defects in both the appearance and the interior of the weld core. From the outside, the solder joint has a flat surface and no defects such as burns or deep indentations. From an internal perspective, there should be a properly sized weld nugget, which should be a very dense casting structure and free from defects such as shrinkage, porosity, and cracks.
電容儲(chǔ)能點(diǎn)焊機(jī)如果在點(diǎn)焊時(shí),焊件清理不好,規(guī)范選擇不當(dāng),都能引起缺陷的產(chǎn)生。點(diǎn)焊的缺陷主要有:
Capacitor energy storage spot welding machines can cause defects if the welding parts are not cleaned properly and the specifications are not selected properly during spot welding. The main defects of spot welding are:
1.未熔透:
1. Incomplete penetration:
未熔透即在點(diǎn)焊時(shí),沒(méi)有形成“扁豆”樣的鑄造點(diǎn)焊組織。這種缺陷危險(xiǎn)。它會(huì)大大降低焊點(diǎn)的強(qiáng)度。而且這種缺陷一般不能從外觀上檢查出來(lái)。儲(chǔ)能點(diǎn)焊機(jī)產(chǎn)生未熔透的主要原因是由于焊接電流密度太小或焊接時(shí)間短使焊接部位加熱不足所造成的。造成焊接部位電流減小的原因是多種多樣的。
Lack of penetration refers to the lack of formation of a "lentil" like cast spot welding structure during spot welding. This defect is dangerous. It will greatly reduce the strength of the solder joint. Moreover, such defects are generally not detectable from the appearance. The main reason for incomplete fusion in energy storage spot welding machines is due to insufficient heating of the welding area due to low welding current density or short welding time. There are various reasons for the decrease in current at the welding site.

如:①焊接工藝規(guī)范調(diào)節(jié)不合適,②二次回路電阻增大,③有部分分流現(xiàn)象,④網(wǎng)絡(luò)電壓下降等。
For example, ① improper adjustment of welding process specifications, ② increase in secondary circuit resistance, ③ partial shunt phenomenon, ④ decrease in network voltage, etc.
2.飛濺:
2. Splash:
飛濺在儲(chǔ)能點(diǎn)焊機(jī)中經(jīng)長(zhǎng)出現(xiàn)。少許的飛淺是不可避免的,如果飛濺太大,會(huì)造成壓痕過(guò)深。工作表面的凹陷太深,會(huì)造成焊核強(qiáng)度明顯下降。飛濺有兩種,即初期飛濺和末期飛濺。初期飛濺是電流閉合瞬間產(chǎn)生的。其主要原因是由于予壓時(shí)間太短或焊件表面不清潔及壓力小所造成的。儲(chǔ)能點(diǎn)焊機(jī)末期飛濺是在通電末期產(chǎn)生的,其原因主要是焊接電流太大或焊接時(shí)間太長(zhǎng),核內(nèi)熔化的金屬大到周?chē)苄原h(huán)在電壓力下已經(jīng)包不住了,而造成液體金屬的外溢。
Splash appears in the energy storage spot welding machine for a long time. A slight splash is inevitable, and if the splash is too large, it can cause excessive indentation. If the depression on the working surface is too deep, it will cause a significant decrease in the strength of the weld nuggets. There are two types of splashes, namely early splashes and late splashes. The initial splash is generated at the moment of current closure. The main reason for this is due to the short pre pressing time, unclean surface of the welded part, and low pressure. The final splashing of energy storage spot welding machines occurs at the end of the power cycle. The main reason is that the welding current is too high or the welding time is too long, and the molten metal in the core is so large that the surrounding plastic ring cannot wrap it under electrical pressure, resulting in the overflow of liquid metal.
飛濺的辦法是查找產(chǎn)生飛濺的原因,適當(dāng)?shù)卣{(diào)節(jié)焊接規(guī)范或改善工件表面質(zhì)量。
The method to eliminate splashing is to identify the cause of splashing, adjust welding specifications appropriately, or improve the surface quality of the workpiece.
