Embodiment Construction

[0021] figure 1 A tube 11 is shown as an exemplary component for the manufacture of a tube wall register 10 for a boiler wall. The boiler walls comprise a combustion chamber wall enclosing the combustion chamber of the boiler and a cladding wall enclosing the flue gas passages adjacent to the combustion chamber. The boiler walls are constructed so as to be airtight.

[0022] Often, for example, in the manufacture of boiler walls, it is necessary to connect the tubes 11 to each other in a fluid-tight manner by welding (eg TIG welding) on ​​the two affected tube ends. In doing so, the tubes 11 of adjacent boiler wall registers 10 are connected to each other. This connection is made by welding, for example by TIG welding. The tubes 11 of two adjacent duct wall registers 10 are connected to each other at the circular seam register abutment and / or the straps 12 of two adjacent duct wall registers 10 are connected at the register The abutments are connected to each other by mean...

Abstract

The invention relates to a method for welding thin-walled tubes by means of peak temperature temper welding. The invention relates to a method for connecting two components by TIG welding, said components consisting of an air-curing steel alloy, in particular of the material T23 or T24. A joint ( 17 ) is created between the components to be connected, which, in particular, widens from the inside to the outside. First, the root layer is welded in the area of ​​the inner side. Subsequently, the filler layer is welded next to the root layer so that the joint is at least 90% filled. Finally, the cover layer is welded to the filling layer, whereby the welding parameters are predetermined in such a way that on the inner side the temperature is set in the optimum temperature range in the region of the root layer.

Description

technical field [0001] The present invention relates to a method for connecting two adjacent components, in particular two tubes of a tube wall register, to create a boiler wall. The boiler wall of the steam generator comprises tubes through which the medium flows, said tubes being connected to each other by straps arranged on the tubes and forming a closed boiler wall. The duct wall registers may be connected to each other along the circular weld register abutment by means of straps on the strap register abutment and / or by tubes. The joining is done by welding, in particular by means of the inert gas tungsten welding method. Background technique [0002] During operation, the boiler walls of the steam generator are subject to large strains. In particular with regard to the pipes through which the medium material flows, it is therefore necessary to use pressurizable materials. Boiler walls comprise the combustion chamber wall closing the combustion chamber of the boiler a...
