Method for welding balls
View Patent ↗A method for welding balls provides a component, provides at least two balls, places at least one first ball of the at least two balls on the component, and applies an electrical voltage in such a manner that a current flows through the at least two balls and through the component, wherein the at least two balls are simultaneously welded together and the first ball is simultaneously welded to the component.
1. A method for welding balls, comprising:
providing a component;
providing an annular ring-shaped holding device;
providing at least two balls, wherein the annular ring-shaped holding device holds the at least two balls relative to one another during the welding process;
mounting at least one first ball of the at least two balls onto the component, wherein two balls of the at least two balls contact one another; and
applying an electrical voltage such that a current flows through the at least two balls and through the component, wherein simultaneous welding of the at least two balls and simultaneous welding of the first ball and the component occurs.
2. The method according to claim 1 , wherein
welding is performed without a protective gas atmosphere during the welding process.
3. The method according to claim 1 , wherein
more than two balls are used, and
at least two of the balls are simultaneously welded to the component and at least two of the balls are likewise simultaneously welded to one another.
4. The method according to claim 1 , wherein
the ring-shaped holding device is placed onto the component,
at least two balls bear against an inner side of the ring-shaped holding device and against the component, and
at least one further ball bears against the at least two balls which bear against the inner side of the ring-shaped holding device and which bear against the component.
5. The method according to claim 1 , wherein
the annular ring-shaped holding device is composed at least at an inner side, or is composed entirely, of an electrically nonconductive or electrically insulating material.
6. The method according to claim 1 , wherein
the at least two balls are pressed against the component by a welding electrode during the welding process.
7. The method according to claim 1 , wherein
the at least two balls are steel balls.
8. The method according to claim 7 , wherein
the component is a steel component.
9. The method according to claim 1 , wherein
the component is a steel component.
10. The method according to claim 1 , wherein
the electrical voltage with which the welding current is generated is a DC voltage.
11. A method for welding balls, comprising:
providing a component;
providing a tubular holding device;
providing at least two balls, wherein the at least two balls are introduced into the tubular holding device, arranged one behind the other in a row, and successive balls contact one another;
mounting at least one first ball of the at least two balls onto the component; and
applying an electrical voltage such that a current flows through the at least two balls and through the component, wherein simultaneous welding of the at least two balls and simultaneous welding of the first ball and the component occurs;
wherein after simultaneous welding of the at least two balls and simultaneous welding of the first ball and the component occurs, the tubular holding device is removed.
12. The method according to claim 11 , wherein
welding is performed without a protective gas atmosphere during the welding process.
13. The method according to claim 11 , wherein
the tubular holding device is composed at least at an inner tube side, or is composed entirely, of an electrically nonconductive or electrically insulating material.
14. The method according to claim 11 , wherein
the at least two balls are pressed against the component by a welding electrode during the welding process.
15. The method according to claim 11 , wherein
the at least two balls are steel balls.
16. The method according to claim 11 , wherein
the component is a steel component.
17. The method according to claim 11 , wherein
the component is a steel component.
18. The method according to claim 11 , wherein
the electrical voltage with which the welding current is generated is a DC voltage.
