Patent ID: 6936785

Claim:
A welding method for arc-welding a lead of a device to an electrically conductive plate, comprising: providing a welding construction having first and second slanted edges formed to narrow and taper a leading end of the electrically conductive plate along a widthwise direction, such that the slanted edges defines a tip at the leading end of the electrically conductive plate, forming a slit extending into the first slanted edge at a location offset from the tip and continuing at least toward a widthwise center of the electrically conductive plate and dimensioned to accommodate the lead, a meltable portion being defined between the slit and the second slanted edge of the electrically conductive plate including the tip, the meltable portion having a volume necessary to substantially close an opening of the slit; inserting the lead into the slit; and performing a welding step so that arcs are created at the leading end of the electrically conductive plate to melt the meltable portion so that a molten material of the meltable portion is filled into the slit and substantially around the lead.
