摘要： The invention introduces a method for generating, in layers, an application structure (420) made of high heat resistant super alloys on a substrate (415). A powdery construction material is melted by an energy beam at a working point, wherein the working point is guided across the substrate along a primary movement direction and thus swings transversely to the primary movement direction. According to the invention, the working point thereby swings from a first edge of a respective layer of the application structure to a second edge of the layer. In this way, a time interval passes between departure from a respective edge and a return to the respective edge directly following the departure, such that a melt bath on the respective edge solidifies into a paste-like zone during the time interval.

摘要： The invention relates to a welding method for welding workpieces (9) made of highly heat-resistant superalloys. Said method includes: generating a heat input zone (11) on the workpiece surface (10) by means of a heat source (3); feeding welding filler material (13) into the heat input zone by means of a feeding device (5); and generating a relative motion between the heat source (3) and the feeding device (5) on one hand and the workpiece surface (10) on the other hand by means of a conveying device (15). Furthermore, according to the welding method, the mass feed rate is ≤ 350 mg/min.
