Abstract
According to the invention a welding device for welding workpieces is provided. The welding device comprises a welding means for making a welding seam on workpieces and a cleaning nozzle in order to emit a cryogenic medium onto the surfaces of the workpieces in the area of their welding seam to be formed. The distance between the welding means and the nozzles is at least 5 cm.
Claims15
A welding device for welding workpieces comprising a welding means (2) for making a welding seam (3) on workpieces (6) and a nozzle (7) in order to emit a cryogenic medium (8) onto the surfaces (5) of the workpieces (6) in the area of their welding seam to be formed, the distance between the welding means (2) and the nozzle (7) being at least 5 cm.
A process for welding workpieces,
- wherein a cryogenic medium (8) is impacted on the surfaces (5) of the workpieces (6) in the area of their welding seam to be formed in order to clean and cool this area and the workpieces are welded with each other in the cleaned area.
