Gatland announced his squad well ahead of schedule for the Scotland clash this weekend.
The Welsh have made one change to their starting XV from the side that beat England, with Adam Beard coming into the side for the trip to Edinburgh to face Scotland on Saturday.
Beard, who featured in the last nine matches for Wales, returns to the starting line-up in place of the injured Cory Hill and will once again pack down alongside captain Alun Wyn Jones in the second row.
Rob Evans, Ken Owens and Tomas Francis again form the front-row with Josh Navidi, Justin Tipuric and Ross Moriarty named in the back-row.
Gareth Davies and Gareth Anscombe start at scrum-half and fly-half respectively with Hadleigh Parkes and Jonathan Davies forming the midfield partnership.
Josh Adams, George North and Liam Williams line-up in the back-three.
Elliot Dee, Nicky Smith and Dillon Lewis provide the front row cover on the bench with Jake Ball and Aaron Wainwright completing the forward contingent. Aled Davies, Dan Biggar and Owen Watkin provide the backline cover.
