Provided is a method of assembly for a noise suppressor using specific welding and assembly procedures. By welding the inner portion of a noise suppressor to form a semi complete core an outer tube can then be placed over said core to reinforce the noise suppressor as a whole. The described process allows for an overall reduction of tube wall thickness and provides for a reduction of weight. By affixing each baffle, spacer, end cap and mount together as a whole the strength of the entire unit is multiplied. My method is not restricted to any particular baffle technology but may in fact be incorporated into any design where circumferential fusion welds may be used.
