Hey all, I have just started making an arched window at work. I have made templates for both the sash and the frame. The arch is to be joined in two places. My question is what joint should use to fix them together? They will be cut roughly, glued together and I will use my templates on the ring fence to finish it off.

one idea
I'd use a quasi-mitered saddle joint, where the "miter" is a radial of the arc. That would give you a nice surface, plus plenty of strength. Others may have alternative ideas.
Arched Window
'Arch is to be joined in two places.' Arched jamb or sash? Is the joint for length between two curved sections of sash or jamb, or are you trying to to join curved members to straight members? Is this a half round window, a segment arch window, or a half round with straight legs? Each is addressed differently in our shop.
Curved sash can be sucessfully butted with well placed long grain splines. Jambs are built full size, by bricklaying curved segments, then sawing the final curve, then joining to straights with half laps. Sash is joined to straights with coped and stuck motise and tenon. You can find more info at Woodweb forums, since they address architectural work for professional woodworkers.
