The event will start on October 17 and run through to October 20.
Wetherill, a men’s class six athlete, features in a 14-strong British squad.
The 28-year-old three-time Paralympian is looking forward to the event.
He said: “My preparation has been really good. I’ve always said my level correlates to my fitness and how injury-free I am and I’m in good shape right now so fingers crossed it can stay the same.
“I’m just going to try and play as I know I can play and I’m sure that will be enough. I’m approaching the World Championships the same way that I would a local league match – obviously there is a bit more riding on it – but I’m just going to enjoy it.
“Obviously a medal is what you aim for and work towards and it is in the back of my mind – but what is motivating me now is to play the best that I can play and be the best player I can. I feel that I am in the right place now to go out and produce my best.”
