極柱結(jié)構(gòu)取決于電池型號與電池容量的大小范圍。極柱都是最常用的外極柱結(jié)構(gòu)，膠體密封電池也用此極柱結(jié)構(gòu)。
極柱的焊接方法常有手工焊接與自動焊接。自動焊接中有傳統(tǒng)氣焊；感應加熱焊；鎢極弧焊。
極柱的焊接工藝包括如下兩類。
①極柱焊接質(zhì)量對電池來說至關(guān)重要，通常最小6mm的焊接區(qū)要確保完全焊好，必須具有：a．在振動情況下具有穩(wěn)定的機械強度；b．有高電流的導電性；c．焊區(qū)有強耐酸蝕性；d．防止在熱作用下出現(xiàn)焊點開裂及微觀結(jié)構(gòu)變化的危險。
②極柱焊接工藝的改進：a．感應加熱焊接技術(shù)；b．鎢極弧焊技術(shù)。
The pole pillar structure is decided by all of the scopes of battery model number and battery capacity.The pole pillar is the all the inest common use outside pole pillar structure, the gum body seals completely battery to also use this pole pillar structure.
The pole pillar welds a method to often have handicraft to weld and automatically weld.Automatically weld medium have a tradition the spirit the Han;Respond to heat Han;The Wu pole Hu Han.
Pole pillar's welding a craft is included as follows 2 types.
①Pole the pillar weld the quality to battery to the pass importance, the welding of usually minimum 6 mms area wants to ensure complete Han good, have to have:A.have stable machine strength under the sistuation that vibrate;B.have the electrical conductivity of high electric current;C.the Han area has strong acid-proof eclipse;D.prevent°from under the hot function appearing a Han point open to split and the tiny view structure change of danger.
②The pole pillar welds the improvement of craft:A.respond to heat to weld a technique;B.the Wu pole Hu Han technique.
