Jig device for laser welding and jig system including the same

A jig system for laser welding comprising:

• a jig device for laser welding that comprises:
• 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 first side 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;
• the jig system further comprising:
• a support device configured to rotatably couple and support an end portion of the first side of the refrigerant pipe;
• and
• a jig rotating device disposed to be spaced apart from the support device at a predetermined gap and configured to hold and rotate one side of the jig device.
