本発明は鉛蓄電池の極板耳部と極柱との溶接時

鉛の夫々の熱容量が異なるため、一定の火炎の下
での溶融バランスがとれ難い欠点があつた。 Conventionally, the additional lead used when welding the lead-calcium alloy electrode plate ears and pole posts has been made of a lead-calcium alloy, but this alloy tends to form an oxide film on the surface and is difficult to use when melting molten lead. Because it hinders fluidity, it has the disadvantage of poor fusion, difficult welding techniques, and poor welding. Furthermore, since the heat capacities of the electrode plate ears, pole columns, and additional lead that are melted are different, it is difficult to maintain a balance in melting under a constant flame.
本発明は溶接用の足し鉛に純鉛を用いることに
より上記欠点を解消したもので、以下一実施例に
基づいて詳細に説明する。 The present invention solves the above drawbacks by using pure lead as additional lead for welding, and will be described in detail below based on one embodiment.

続を完了した接続部の要部外観斜視図である。 Next, the ear part 2 of the pole plate 7 and the pole post 3 are placed in the mold 1.
, and add additional lead 4 made of pure lead for welding into the mold 1 by melting it with a burner 5 and supplying it to the mold 1.
A strap 6 is formed by welding these together. FIG. 2 is an external perspective view of the main part of the connection part where the connection between the ear part 2 of the pole plate 7 and the pole post 3 is completed by the method of the present invention.

なる効果がある。 As described above, since the present invention uses added lead of pure lead, it is difficult to form an oxide film compared to the case where added lead of conventional lead-calcium alloy is used. Since it has a higher melting point and can be welded at high temperatures, it improves weldability and improves the heat capacity balance of each member during welding. In addition, when welding is completed, the lead-calcium alloy that forms the pole plate ears and the pole column is fluidly mixed with the pure lead that forms the additional lead to form the strap. - If the calcium percentage of the calcium alloy is 0.07 to 0.1%, the calcium percentage of the strap after welding is 0.01 to 0.1%.
It is 0.05%, which has the effect of providing flexibility in the strap part and eliminating the risk of cracking in the welded part due to vibration impact.

At the same time, the present invention can also be used to connect common lead-antimony based alloy electrode plate ears and pole posts. In addition, in terms of cost, by using pure lead instead of conventional lead.

It has the advantage of being able to keep it as low as %.
