Zusammenfassung:	The invention discloses an atomization spray disc and a method for preparing narrow particle size alloy powder for additive manufacturing by gas atomization, and belongs to the field of powder preparation. The technical problem of low yield of preparation of narrow particle size alloy powder is solved. The atomization spray disc comprises a spray disc main body, a spray disc upper connecting bodyand a spray disc lower connecting body, wherein an annular seam is formed between the spray disc lower connecting body and the spray disc upper connecting body or an annular hole is formed in the spray disc upper connecting body. A method for preparing the narrow particle size alloy powder for additive manufacturing by gas atomization comprises the following steps that S1, fine particle size alloypowder with the median particle size of 60 micrometers or less is prepared by adopting an annular seam spray disc; coarse particle size alloy powder with the median particle size of 60 micrometers orabove is prepared by adopt
