The invention relates to a vessel head (1) for a vessel (30), comprising: a vaulted dish area (2) having a vault radius R, a connecting contour (5) comprising in a first contour section (6) a first radius of curvature (r1) and in a second contour section (7), a second radius of curvature (r2), wherein the first radius of curvature (r1) is larger than the second radius of curvature (r2) and a knuckle area (3) surrounding the dish area (2) and tracing the connecting contour (5) is configured between the connecting contour (5) and the dish area (2) comprising, extending along the first contour section (6), a first knuckle section (10) having a first knuckle radius (dB) and a second knuckle section (12) having a second knuckle radius (r1k2). The invention further relates to a tool and a method of manufacturing such a vessel head (1).

In an example, a method for milling a sink is disclosed. The method includes receiving a metal sheet, positioning the metal sheet in a receiving assembly for a milling machine, and scoring the metal sheet via a cutter of the milling machine. The metal sheet is scored along an axis corresponding to a bend of the sink. The method also includes manipulating the metal sheet to form the sink.

The present invention relates to a pressure tank in stainless steel to be used as a water heater. The tank is provided by two identical tank halves (12a, 12b; 14a, 14b). The two tank halves are joined about a common dividing plane (7) and have a longitudinal axis (26) that lies in the dividing plane (7) so that an extended tank is provided. The tank halves have welding flanges (22a, 22b) that are placed against each other in the joint dividing plane (7) and are joined together by welding or melting of the flanges (22a,22b) to a watertight tank. The plate thickness is calculated according to the maximum test pressure of the tank and not limited by the welding. An efficient welding of the internal welding seam (24), by placing the tank in a rig and rotating the tank, provides safe protection against corrosion in the weld.
