An inflator for inflating an air bag includes a housing. A quantity of gas generating material is disposed within the housing. The gas generating material when ignited generates gas for inflating the air bag. An igniter is actuatable to ignite the gas generating material. A weld adaptor is welded to the housing. A body of injection molded plastic material adheres to both the igniter and the weld adaptor to attach the igniter to the weld adaptor. The weld adaptor is welded to a cover part of the inflator housing.
