Beschreibung
Zusammenfassung:	Provided is a fabrication method of a battery module case accommodating a battery cell, the method including: operation (a) of inputting a first base material member and a second base material member included in the case which accommodates the battery cell therein; operation (b) of performing a surface treatment by emitting a laser to a surface region including a joining region formed by contacting the first base material member and the second base material member with each other; and operation (c) of forming a weld joint by emitting the laser to the joining region, thus increasing a recognition rate in operating an auto position alignment (APA) function regardless of a surface condition of the base material of the battery module case.
