強度との相関から溶接強度の測定検査判定ができる。As described above, according to the method and apparatus for manufacturing a lead wire for an aluminum electrolytic capacitor according to the present invention, the surface temperature of the aluminum wire is measured in a non-contact manner at the next position after heating and welding. The welding strength can be measured and judged based on the correlation between the surface temperature of the aluminum wire and the welding strength.

Since it can be fed back to the gas flow rate control, it is possible to continuously measure the welding strength in the drawing lead wire manufacturing device in a non-contact manner.
This has the effect of reducing variations in welding strength, reducing the number of production steps, and improving production yield and production control.
