Abstract
A method is provided for welding a substrate, in which an energy source and/or a material feed is or are moved in an oscillating motion over the surface of the substrate. The oscillating movement in a vertical and/or horizontal direction during welding results in smaller grains, which prevent the formation of fractures during welding.
Description
- This application is a continuation application of U.S. application Ser. No. 15/110,773, filed Jul. 11, 2016, and entitled “OSCILLATING WELDING METHOD”, which claims priority to PCT Application No. PCT/EP2014/053389, having a filing date of Feb. 21, 2014, based off of DE Application No. 102014200834.4 having a filing date of Jan. 17, 2014, the entire contents of which are hereby incorporated by reference.
- The following relates to a welding method in which the welding beam is moved in oscillation.
- During the laser deposition welding of nickel-based superalloys having a high proportion of metallic phase γ′, hot cracks can already form during solidification of the melt. By reducing the beam diameter of the laser with a circular intensity distribution, smaller grains are achieved and solidification cracks can be avoided, but this reduces the rate of deposition of the material.
- An aspect relates to a welding method which makes it possible to achieve small grains and high deposition rates.
- An oscillating motion in the horizontal direction should cause the solidification front to change constantly so as to produce an oscillating solidification form. As a result of a constantly changing solidification function, the grain growth is interrupted during the solidification of the melt and the microstructure solidifies in fine-grained form. The fine-grained quality of the microstructure causes the welding residual stresses which thus remain to be distributed over the grain boundaries so as to avoid cracks in the weld seam or in the weld metal.
- The welding method can be remelting or deposition welding. Both methods produce a melt and a solidification front.
- Some of the embodiments will be described in detail, with reference to the following figures, wherein like designations denote like members, wherein:
-
FIG. 1 shows an arrangement for welding; and -
FIGS. 2-4 show the sequence of the oscillating motion. - The figures and the description represent only exemplary embodiments of the invention.
-
FIG. 1 shows a device 1 for a welding method, in particular a laser welding method, on the basis of which embodiments of the invention will be explained in a non-limiting manner. - The method is thus not limited to laser welding methods, but is also applicable for electron beam welding methods and other plasma welding methods with corresponding energy sources.
- Material 8 is deposited onto a
substrate 3, which, in the case of turbine blades or vanes, is a nickel-based or cobalt-based superalloy having a high γ′ proportion and therefore generally an alloy having poor weldability. - A
welding bead 6, as part of the deposition weld, has already been generated. - In the case of a remelt method, the welding bead is the remelted region.
- At those points where a laser, as an
exemplary energy source 13, directs the laser beams 15 (FIG. 2 ) thereof onto thesubstrate 3, there is amelt pool 7. - A powder nozzle, as the material feed 14, preferably feeds powder 8, with the powder 8 being melted, in this case by
laser radiation 15. The material 8 is fed in the form of powder, but may also be fed as a wire. Thislaser radiation 15 is in particular pulsed. - The area to be welded is made up of a plurality of welding beads lying next to one another and if appropriate one above another and preferably has, in at least one direction, a length of greater than or equal to 4 mm.
-
FIGS. 2, 3 and 4 show the for example triangular 44; 31, 34; 43, 49, 55 oscillating motion of thelaser radiation 15. - The oscillating motion is preferably affected only in one plane.
- The
triangular shape 44; 31, 34; 43, 49, 55 is preferably an acute-angled triangle, with a height (in the direction of movement 2) of thetriangular shape 44 preferably being at least twice the magnitude of thebase 24. - An oscillating motion preferably proceeds as follows:
- From a first starting point 21 (
FIG. 2 ), thelaser radiation 15 moves counter to the direction ofmovement 2 at an angle with respect to the direction ofmovement 2 as far as afirst deflection point 22, where thelaser radiation 15 is then moved perpendicularly with respect to the direction ofmovement 2 in adirection 24 as far as asecond deflection point 23. - In order that the
laser radiation 15 continues to move along as a whole in the direction ofmovement 2, it then moves obliquely with respect to the direction ofmovement 2 in the direction ofmovement 2 in a first oblique direction 30 (FIG. 3 ) to asecond starting point 31, which lies downstream of thefirst deflection point 22 in the direction ofmovement 2. Thesecond starting point 31 is level with thefirst deflection point 22, displaced by adistance 4. - From there, the
laser radiation 15 then moves forward again as far as athird deflection point 33. Thethird deflection point 33 lies downstream of thefirst starting point 21 in the direction ofmovement 2. A connecting line betweenpoints movement 2. From there, thelaser radiation 15 oscillates again at an angle with respect to the direction ofmovement 2 counter to the direction ofmovement 2 as far as afourth deflection point 34. - The
fourth deflection point 34 is level with thesecond starting point 31 in a perpendicular direction with respect to the direction ofmovement 2 and level with thesecond deflection point 23 in the direction ofmovement 2. - In a second perpendicular direction of
movement 36 which is perpendicular with respect to the direction ofmovement 2, thelaser radiation 15 moves back to thesecond starting point 31 of the triangular oscillating motion (FIG. 3 ). - The further triangular oscillating motion proceeding from
FIG. 3 can then be identified inFIG. 4 , in which thelaser radiation 15 oscillates in a secondoblique direction 40 with respect to the direction ofmovement 2 in the direction ofmovement 2 to theseventh deflection point 55. Theseventh deflection point 55 is level with thepoint 34. From there, thelaser radiation 15 then moves in the direction of thethird deflection point 33 to afifth deflection point 43, which lies downstream of thedeflection point 33 as shown inFIG. 3 . - From the
fifth deflection point 43, thelaser radiation 15 moves obliquely with respect to the direction ofmovement 2 counter to the direction ofmovement 2 in a thirdrearward motion 46 as far as asixth deflection point 49. From thesixth deflection point 49, thelaser radiation 15 oscillates perpendicularly with respect to the direction ofmovement 2 to theseventh deflection point 55. - Effectively, a triangular shape is always displaced in the direction of
movement 2 for the course of thelaser radiation 15, such that the triangular shapes overlap. - This represents only one procedure for the preferably triangular oscillation.
- On account of embodiments of the invention, this procedure achieves improved material properties.
- Although the present embodiments of has been disclosed in the form of preferred embodiments and variations thereon, it will be understood that numerous additional modifications and variations could be made thereto without departing from the scope of the invention.
- For the sake of clarity, it is to be understood that the use of ‘a’ or ‘an’ throughout this application does not exclude a plurality, and ‘comprising’ does not exclude other steps or elements.
