1. A jig device for laser welding, for supporting a refrigerant pipe to which a fixing part of a charging port is coupled in order to bond the fixing part of the charging port to the refrigerant pipe using a laser, the jig device comprising:
a jig body having a semi-oval shaped seating groove in which a lower side of a refrigerant pipe to which a charging port is coupled is seated;
a first pressing block provided in an upper portion of a firstside of the jig body and having a first groove part configured to press an upper portion of a first side of the refrigerant pipe and an upper portion of a first side of a fixing part of the charging port at a lower surface thereof; and
a second pressing block provided at an upper portion of a second side of the jig body and having a second groove part configured to press an upper portion of a second side of the refrigerant pipe and an upper portion of a second side of the fixing part of the charging port at a lower surface thereof,
wherein the first groove part and the second groove part are formed in a semi-oval shape to form an oval-shaped space when in contact with the semi-oval shaped seating groove, and the refrigerant pipe and the fixing part of the charging port are laser welded in a close contact state with each other in the oval-shaped space.
