Abstract
The invention relates to a crossjet assembly for generating a gas flow that is conducted between a laser source (40, 41) and a welding region (42) in order to remove contaminants moving towards the laser source. The gas flow crosses the region between the laser source and the welding site numerous times.
Claims15
A device for removing contaminants in a work zone, the device comprising:
- a housing;
- a cutout portion in the housing that defines a contaminant removal area;
- a helically running conduit having windings disposed in the housing, a first end configured to receive a flow of air, and a second end located proximate to the contaminant removal area;
- wherein the windings are interrupted in the contaminant removal area;
- wherein interrupted portions of the windings in the contaminant removal area are associated with opposing exit and entrance openings of the conduit;
- wherein the contaminant removal area receives multiple passes of the flow of air, such that contaminants travelling from a working area in the work zone to a working device in the work zone are exposed multiple times to the same flow of air;
- and
- wherein the second end of the conduit is disposed in a portion of the housing that extends beyond the pairs of opposing exit and entrance openings, such that the flow of air leaving the second end is conducted laterally past, and away from, the contaminant removal area.

A device for removing contaminants in a work zone, the device comprising:
- a housing having a rectangular through-opening with opposing walls;
- a conduit disposed in the housing, and configured to receive a flow of air;
- a cutout portion in the housing that defines a contaminant removal area;
- and
- a plurality of recesses disposed in the opposing walls of the through-opening;
- wherein the contaminant removal area receives multiple passes of the flow of air, such that contaminants travelling from a working area in the work zone to a working device in the work zone are exposed multiple times to the same flow of air.
