Arrangement for a protective atmosphere for tungsten - inert gas - welding

摘要

a chamber for the wurzelseite a weld during welding with inert gas to prevent oxidation of the weld to protect covers a majority of kammerelementen, a floor, sides, and an open top of the chamber stirnwu00e4nde and form, as well as the flexible connection of a lagerungseinrichtung kammerelemente themselves.the kammerelemente include a first set of u-shaped elements with schenkelstu00fccken, an upper base and a lower base with a between the sole components, but without outer defined interior, with the upper base of the elements lochungen trained and had each other gengesetzten edges of the schenkelstu00fccke excerpts are availableand a second set of u-shaped elements with legs and a base.furthermore, the kammerelemente included between the legs of the u-shaped elements of the second sentence gelenkbolzen kammerelemente mounted, with the first sentence and the second sentence kammerelemente together are arranged alternately and the framing of the first sentence of the u - reduced in the gelenkbolzen elements of the second sentence of these elements togetherin such a way that the elements of the first sentence with respect to an adjacent element of the second set of u-shaped elements rotate. it will also positioniereinrichtungen or structures revealed to the chamber in the vicinity of a workpiece in position.
