Abstract

Die Erfindung betrifft ein Rohrschweißverfahren wobei zwei ein Rohrende aufweisende Bauteile (1, 2), beispielsweise Rohrstummel (1, 2) oder Rohrflansche mit einander zugewandten oder stumpf aneinander liegenden Rohrenden aufgespannt werden und an ihren einander zugewandten oder stumpf aneinander liegenden Rohrenden mit einer umlaufenden Schweißnaht verschweißt werden. Die Erfindung zeichnet sich dadurch aus, dass an einer für den Beginn der Schweißnaht vorgesehenen Position der beiden aufgespannten Rohrenden vorab jeweils eine vom Außenumfang radial nach innen verlaufende Ausnehmung in die Stirnfläche beider Rohrenden eingebracht wird, indem dort eine in Radialrichtung verlaufende Bohrung, insbesondere Durchgangsbohrung erzeugt wird, welche die beiden miteinander fluchtenden Ausnehmungen in den Stirnflächen der beiden Rohrenden bildet, und dann im Bereich der beiden einander zugewandt positionierten Ausnehmungen mit dem Schweißen begonnen wird. Die Erfindung betrifft auch eine zur Durchführung des Verfahrens geeignete Rohrschweißvorrichtung.The invention relates to a pipe welding method wherein two pipe ends having components (1, 2), for example, pipe stubs (1, 2) or pipe flanges are clamped with mutually facing or butted pipe ends and at their mutually facing or blunt abutting pipe ends with a circumferential weld be welded. The invention is characterized in that at a provided for the beginning of the weld position of the two clamped pipe ends in advance from the outer circumference radially inwardly extending recess in the end face of both pipe ends is introduced by there generates a radially extending bore, in particular through hole is, which forms the two mutually aligned recesses in the end faces of the two pipe ends, and then in the region of the two mutually facing positioned recesses is started with the welding. The invention also relates to a pipe welding apparatus suitable for carrying out the method.
