The present disclosure relates to a gas generator comprising a housing, an igniter and a pyrotechnic charge via which gas for filling a gasbag can be provided, wherein the gas generator is free from stored pressurized gas in the idle state, characterized in that each possible diffusion path out of the internal chamber of the housing is sealed relative to the environment of the gas generator by means of a weld seam. The present disclosure also relates to a method for leak testing a pyrotechnic gas generator of this type, wherein, before the gas generator is welded against diffusion, a test amount of helium is introduced into the housing and, in a subsequent leak testing step, a measurement is carried out to determine whether helium is passing out of the housing.
