Apparatus and method for controlled cooling and heating of metallic workpieces in the temperature field during welding, thermal cutting (burning, plasma or laser cutting) or soldering (arc or laser soldering)

摘要

The invention relates to a device and a method, which is carried out by means of the device, for a controlled cooling and / or heating of metallic workpieces I, II (8, 9) in the temperature field (14) during welding, thermal cutting or soldering. In this case, it is possible, by the formation of a substantially a burner (1), a thermal fuel, plasma or laser cutting apparatus or a soldering apparatus in the outer mold following constructed device, which is firmly connected to it and annularly arranged cooling gas supply (3) Cooling gas outlet (4) contains that in the area of action of the temperature field (14) on one or more workpieces I, II (8, 9) already during active working and feeding a modified tool areas of the temperature field (14) successively or simultaneously can be cooled and / or heated. The device implements an open method for cooling, heating the workpiece (s) I, II (8, 9) to be machined.
