The invention relates to a method for the surface treatment of a structure (10) that is additively manufactured from a powder bed, in which the additively constructed structure (10) is subjected to a pulse (1), and in which the residual tensile stress in the surface region of the structure (10) is reduced by the pulse (1). The invention further relates to a device (100) for carrying out the method, to a corresponding method for the additive production of a component, and to a component made of a conventionally non-weldable alloy produced in said manner. 提出一种用于对从粉末床中增材制造的结构(10)进行表面处理的方法，其中增材构造的结构(10)承受脉冲(1)，并且其中结构(10)的表面区域中的残余拉应力通过脉冲(1)降低。还提出一种用于执行方法的设备(100)、一种对应的用于增材制造构件的方法以及一种以所述方式制造的由传统不可焊接的合金构成的构件。
