## Abstract

A method for resistance welding a first component to a second component including inserting the second component, at least by a connecting region, into an opening of the first component by a insertion distance and welding the first component to the second component in the process. An internal dimension of the opening and an external dimension of the connecting region are configured similar to a press fit with each other. The insertion distance is limited by an adjustable external distance limiter. A device is configured for resistance welding the first component to the second component.

## Claims

### Claim 1

A method for resistance welding a first component to a second component, the method comprising:
inserting at least a connecting region of the second component into an opening of the first component by an insertion distance along an insertion direction;
welding the first component to the second component while inserting at least the connecting region of the second component into the opening of the first component by the insertion distance; and
limiting the insertion of the connecting region into the opening to the insertion distance, with an adjustable mechanical external distance limiter spaced apart from the first and the second component in a direction perpendicular to the insertion direction, without contacting the first component or the second component with the adjustable mechanical external distance limiter, wherein:
an internal dimension of the opening and an external dimension of the connecting region are configured similar to a press fit with each other.

### Claim 2 (depends on 1)

The method according to claim 1, further comprising:
holding the first component with a first holding device and holding the second component with a second holding device when at least the connecting region of the second component is inserted into opening of the first component, wherein:
the adjustable mechanical external distance limiter is fixedly connected to one of the first holding device and the second holding device.

### Claim 3 (depends on 2)

The method according to claim 2, wherein the insertion distance is predetermined as a function of an actual distance, defined in the insertion direction, between a section of the first component and a section of the second component and as a function of a setpoint distance, defined in the insertion direction, between the section of the first component and the section of the second component.

### Claim 4 (depends on 1)

The method according to claim 1, further comprising:
determining the insertion distance before commencing inserting at least the connecting region of the second component into the opening of the first component.

### Claim 5 (depends on 1)

The method according to claim 1, wherein welding the first component to the second component includes capacitor discharge press-fit welding.
