Claim:
A method of manufacturing a steel housing, composed of at least two housing components, the method comprising the acts of: applying a corrosion prevention layer comprising zinc or a zinc containing alloy to at least one outwardly facing surface of at least one of the at least two housing components with subsequent passivation; forming a positively locking overlap of an edge of one housing component that is clamped radially into a clamping device with its outer casing surface over an edge of the other housing component via relative movement of the housing components, which components have previously been oriented with respect to one another and in relation to a die that plastically shapes at least one of the edges of the housing components, and before applying the die, clamping one housing component and fitting the other housing component onto the one housing component such that the edges of the housing components overlap, wherein before applying the die, the edge of the one housing components is pre-shaped to form a shoulder projecting radially outward.
