极柱结构取决于电池型号与电池容量的大小范围。极柱都是最常用的外极柱结构，胶体密封电池也用此极柱结构。
极柱的焊接方法常有手工焊接与自动焊接。自动焊接中有传统气焊；感应加热焊；钨极弧焊。
极柱的焊接工艺包括如下两类。
①极柱焊接质量对电池来说至关重要，通常最小6mm的焊接区要确保完全焊好，必须具有：a．在振动情况下具有稳定的机械强度；b．有高电流的导电性；c．焊区有强耐酸蚀性；d．防止在热作用下出现焊点开裂及微观结构变化的危险。
②极柱焊接工艺的改进：a．感应加热焊接技术；b．钨极弧焊技术。
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.
