PURPOSE:To make the connection between a welding shelf and a lug section firm and improve the corrosion resistance of the connection portion by providing a layer thicker than the lug section on the connection section between the lower section of the welding shelf and the lug section. CONSTITUTION:Regarding a group welding shelf 1 and a lug section 2, the thickness 2b of the connection portion of the lug section 2 below the shelf is made thicker than the thickness 2a of the lug near an electrode plate 3. The connection between the welding shelf 1 and the lug section 2 is made firm accordingly, and the corrosion resistance of the connection portion can be improved. |
