Abstract

A welding component is provided for welding to a component via at least one welding region. The welding component includes: at least one welding indicator arrangement provided on the welding component; and, the at least one welding indicator arrangement includes a welding region minimum indicator to be covered by the at least one welding region and a welding region maximum indicator not to be covered by the at least one welding region.

First claim

What is claimed is:

1. A welding component for welding to a component via at least one welding region, the welding component comprising:
at least one welding indicator arrangement being provided on said welding component;
said at least one welding indicator arrangement including a welding region minimum indicator to be covered by said at least one welding region and a welding region maximum indicator not to be covered by said at least one welding region;
wherein said welding region minimum indicator includes a contour modification of said welding component and said welding region maximum indicator includes a contour modification of the welding component;
wherein said welding component defines an external contour, said at least one welding indicator arrangement including at least one depression region with respect to said external contour of said welding component;
wherein said at least one depression region is a first depression region;
said at least one welding indicator arrangement includes a second depression region with respect to said external contour; and,
said first and second depression regions are disposed in spaced relationship to each other.

2. The welding component of claim 1 , wherein said welding component has a support region for supporting said welding component on a further component to which said welding component is to be welded; and, said welding region minimum indicator has smaller spacing (d) from said support region than said welding region maximum indicator.

3. The welding component of claim 1 , wherein:
said welding component is a connecting piece having a receptacle opening; said welding component has a component support surface for supporting said connecting piece on a further component to be welded to said connecting piece; and,
said at least one welding indicator arrangement is provided on an external circumferential region of said connecting piece.

4. The welding component of claim 3 , wherein said connecting piece is a sensor receptacle connecting piece for an exhaust system of an internal combustion engine.

5. An exhaust system for an internal combustion engine, comprising:
at least one connecting piece, wherein said at least one connecting piece is a welding component for welding to an exhaust gas conducting component via at least one welding region;
said welding component including at least one welding indicator arrangement provided on said welding component;
said at least one welding indicator arrangement including a welding region minimum indicator to be covered by said at least one welding region and a welding region maximum indicator not to be covered by said at least one welding region;
said welding component being said at least one connecting piece having a receptacle opening;
said welding component having a component support surface for supporting said at least one connecting piece on said exhaust gas conducting component to be welded to said at least one connecting piece;
said at least one welding indicator arrangement being provided on an external circumferential region of said at least one connecting piece;
said at least one connecting piece being arranged on said exhaust gas conducting component; and,
said at least one welding region fixing said at least one connecting piece to said exhaust gas conducting component so as to cause said welding region minimum indicator of said at least one welding indicator arrangement to be covered by said at least one welding region and so as to cause said welding region maximum indicator of said welding indicator arrangement not to be covered by said at least one welding region;
wherein said welding region minimum indicator includes a contour modification of said welding component and said welding region maximum indicator includes a contour modification of the welding component;
wherein said welding component defines an external contour, said at least one welding indicator arrangement including at least one depression region with respect to said external contour of said welding component;
wherein said at least one depression region is a first depression region;
said at least one welding indicator arrangement includes a second depression region with respect to said external contour; and,
said first and second depression regions are disposed in spaced relationship to each other.

6. A welding component for welding to a component via at least one welding region, the welding component comprising:
at least one welding indicator arrangement being provided on said welding component; and,
said at least one welding indicator arrangement including a welding region minimum indicator to be covered by said at least one welding region and a welding region maximum indicator not to be covered by said at least one welding region;
wherein:
said welding component defines an external contour;
said external contour includes a first external contour region and a second external contour region offset with respect to said first external contour region;
said welding indicator arrangement includes a transition region disposed between said first and second external contour regions;
said welding region minimum indicator includes a transition from said first external contour region to said transition region; and,
said welding region maximum indicator includes a transition from said transition region to said second external contour region.

7. The welding component of claim 6 , wherein:
said welding component defines a longitudinal axis (L);
said first external contour region is a first external circumferential contour region of said welding component with respect to said longitudinal axis (L);
said second external contour region is a second external circumferential contour region of said welding component with respect to said longitudinal axis (L);
said first external circumferential contour region has a first radial dimension with respect to said longitudinal axis (L);
said second external circumferential contour region has a second radial dimension with respect to said longitudinal axis (L) different from said first radial dimension; and,
a transition from said first radial dimension to said second radial dimension is provided by said transition region.

8. The welding component of claim 7 , wherein said transition region is configured so as to be substantially frustoconical.

9. The welding component of claim 6 , wherein said welding component has a support region for supporting said welding component on a further component to which said welding component is to be welded; and, said welding region minimum indicator has smaller spacing (d) from said support region than said welding region maximum indicator.

10. The welding component of claim 6 , wherein:
said welding component is a connecting piece having a receptacle opening;
said welding component has a component support surface for supporting said connecting piece on a further component to be welded to said connecting piece; and,
said at least one welding indicator arrangement is provided on an external circumferential region of said connecting piece.

11. The welding component of claim 10 , wherein said connecting piece is a sensor receptacle connecting piece for an exhaust system of an internal combustion engine.

12. An exhaust system for an internal combustion engine, comprising:
at least one connecting piece, wherein said at least one connecting piece is a welding component for welding to an exhaust gas conducting component via at least one welding region;
said welding component including at least one welding indicator arrangement provided on said welding component;
said at least one welding indicator arrangement includi
