摘要： Beim Verfahren zum kontinuierlichen Auftragen von Schutzschichten zum Abdecken von einer Längsschweissnaht von Blechrohren wird eine Hotmelt-Masse als flexibler Hotmelt-Faden (28,58) kontinuierlich durch den Schweissarm (18) einer Schweissmaschine geführt, auf die Innenseite der Längsschweissnaht der Blechrohre umgelenkt, von einer Auftragseinrichtung (40,54) angedrückt, geschmolzen und homogen über die Breite der Längsschweissnaht (12) verteilt. Bevorzugt wird gleichzeitig mit der inneren eine äussere Schutzschicht aufgetragen, was erlaubt, Brenn- oder Trocknungsöfen für Lacke mit einem enormen Platz- und Energiebedarf zu eliminieren.
Eine besonders vorteilhafte Anwendung des Verfahrens liegt im Auftragen eines sterilisationsfesten Hotmelt-Streifens auf die Innenseite oder Innen- und Aussenseite der Längs- schweissnaht eines Weissblechdosenmantels.

摘要： To utilize electric resistance welded steel pipes as high-grade steel pipes such as oil well pipes, the qualities of the electric resistance welded steel pipes, in particular, the components of a plasma operating gas in plasma-shielded welding were fundamentally reexamined to reduce penetrator defects. As a result, an effect achieved by adding no or a minor amount of hydrogen, said effect having been ignored by conventional findings, was newly discovered and an optimum plasma operating gas composition was successfully obtained. Provided is a method for producing a plasma-shielded electric resistance welded steel pipe, said method comprising, in shaping a steel sheet into a pipe and welding end faces thereof, applying a voltage to a plasma operating gas that is supplied between a cathode and an anode of a plasma gun to generate a plasma and then shielding the vicinity of a weld part by the plasma, characterized in that the components of the plasma operating gas comprise, in terms of vol%, 70-90% inclusive of N 2 and the balance being Ar and inevitable impurities. Also provided is a method for producing a plasma-shielded electric resistance welded steel pipe, characterized in that the plasma operating gas contains 1 vol% or less of H 2 .
