A device for a controlled cooling and heating of metallic workpieces in the temperature field in the case of welding, thermal separation (focal -, plasma - or laser) or soldering (arc - or laser soldering)

摘要

A device as an open system for a controlled heating and / or cooling of metallic workpieces i, ii (8, 9) in a temperature range (14) during welding, thermal disconnection or soldering, characterized in that a housing (6) with a burner (1) is fixedly connected, which annularly positioned in the housing interior and axially parallel to the central axis of the burner (1) extending cool gas injections (3), the cooling gas outlets (4) with a greater area than the of the protective gas nozzle (5) and which, in the direction of the workpieces to be processed (8, 9) in front of the outlet opening of the protective gas nozzle (5) of the burner (1) are arranged.
