Title:

WELDING METHOD CAPABLE OF IMPROVING WELDING RELIABILITY BY PRECISELY SETTING WELDING PORTIONS OF THE ELECTRODE TAPS

Document Type and Number:

WIPO Patent Application WO/2018/128310

Kind Code:

A1

Abstract:

The present invention provides a method comprising the steps of: forming a tap array by vertically arranging electrode taps such that the electrode taps at least partially overlap each other; irradiating, with light, at least two side surfaces among the side surfaces of the tap array, except surfaces at which the electrode taps overlap each other and surfaces opposite thereto; scanning the planar shape of steps at which the electrode taps do not overlap each other, through light reflected from end portions of the respective electrode taps; scanning only overlapping portions of the electrode taps, except the steps, on the basis of the resulting scanned shape; setting a welding range in the overlapping portions; and performing welding only in the welding range.
