FIELD: machine building.
SUBSTANCE: at least one external bottom and/or housing is equipped with a hole. A coupling is welded to the hole. At least an inner side of a compressed air receiver is equipped with inner coating. Contact surfaces between the housing and external bottoms are made so that they adjoin each other butt-to-butt, back-to-back respectively, and welded to each other without any welding material using laser welding. The coupling is welded to the hole by means of laser or condenser-discharge welding. Inner coating of the compressed air receiver is applied by means of a powder method. At that, the coupling has a recess, a chamfer or a groove located so that burr or ring-shaped projection formed with the coupling remains between itself and the receiver.
EFFECT: easy manufacture and lower cost of a receiver.
