A method for manufacturing a diaphragm support member with a diaphragm support made of a sintered metal having a diaphragm layer, comprising at least the following steps: a. providing a laminar or tubular diaphragm support made of a porous sintered metal with a surface that is provided for the purpose of being coated with the diaphragm layer; b. providing a metallic connecting element for connecting the diaphragm support to a gas-carrying line; c. connecting the diaphragm support and connecting element with a weld seam to the diaphragm support member and forming a first connection zone between the weld seam and diaphragm support and a second connection zone between the weld seam and the connecting element; d. arranging a metal layer on the surface and the weld seam so that the metal layer covers at least the first connection zone; d. cohesively joining the metal layer at least with the surface and the weld seam; and e. coating at least portions of the surface and at least portions of the foil with the diaphragm layer. A diaphragm support member comprising at least one diaphragm support made of a porous sintered metal and a metallic connecting element for connecting the diaphragm support to a gas-carrying line is also provided.
