## Abstract

A welding robot (1) comprising a stand (2) pivotally receiving a trunk-forming portion (3) having one end (5) of an articulated arm (6) pivotally mounted thereon, the arm having an opposite end (7) provided with a clamp (8) fitted with welding electrodes, the robot including an electrode grinder (9) mounted on a portion (3) of the robot that is situated in a zone that is accessible to the clamp.

## Claims

### Claim 1

A welding robot (1) comprising a stand (2) pivotally receiving a moving assembly comprising a trunk-forming portion (3) having one end (5) of an articulated arm (6) pivotally mounted thereon, an opposite end (7) of the arm being provided with a clamp (8) fitted with welding electrodes, the robot including an electrode grinder (9) mounted on its moving assembly in a zone that is accessible to the clamp, the grinder (9) being mounted on a horizontal slideway (15) secured to the trunk-forming portion (3) to extend in front of a front face of the trunk-forming portion and to pivot together with the trunk forming portion.

### Claim 2

A welding robot comprising:
a stand;
a moving assembly pivotably mounted on said stand and including a trunk-forming portion; and
an articulated arm having a first end pivotably connected to said trunk-forming portion and an opposite second end having a clamp fitted with welding electrodes;
an L-shaped bracket having a first portion extending from a side of said trunk-forming portion and substantially perpendicular to a front face of said trunk-forming portion and a second portion extending substantially parallel to said front face, said second portion forming a slideway; and
an electrode grinder slidably adjustable in said slideway.
