Abstract
A hollow body and method for making the same are proposed for a sanitary fitting such as a mixing valve for hot and cold water lines. The hollow body may be fabricated as a simple sheet material part and contains water guides in its interior. The water guides are produced by inserting a simple sheet material part into the interior of the hollow body. The sheet material part is fixed in place and subsequently welded to the inner side of the hollow body. Welding can be done more particularly with the aid of a laser enabling the weld to be made from the outer side of the hollow body, as a result of which, welds can be produced at positions which would otherwise not be accessible.
