Publication number: 20050252846Abstract: A method for joining sinter metal elements comprising a carrier sheet having openings filled with a sinter metal for the construction of a sinter metal filter element or sinter metal filter body is disclosed. At least two sinter metal elements having pores for the passage of a fluid to be filtered are disposed adjacent one another and joined along an end section thereof by first introducing fine particles into the pores of the sinter metal elements in an area adjacent to the end sections of the sinter metal elements to be joined, so as to close the pores in that area, and the end sections of the sinter metal filter elements are then joined by heating with a joining material which, upon heating melts and enters the pores of the end section of the sinter metal elements but not the blocked pores in the adjacent area. A filter body produced therefrom is also disclosed.Type: ApplicationFiled: June 21, 2005Publication date: November 17, 2005Inventors: Hermann-Josef Schulte, Jochen Koll
