An explosion-proof housing includes at least one metal housing part having at least one of a housing opening or receiving surface, and a support edge bordering said at least one of a housing opening or receiving surface. A cover part covers said at least one of a housing opening or the receiving surface. The cover part includes a peripheral cover edge which is connected to the support edge in an explosion-proof manner such that in the event of an explosion inside the housing, the explosion is prevented from crossing over to an explosive atmosphere surrounding the housing. A plurality of connection points are formed between the support edge and the cover edge. The connection points include interlocking depressions and protrusions. The protrusions are formed by partial melting of the cover edge. The depressions and the protrusions interlock with play in a longitudinal direction of the housing.
