Description

  

  Verfahren zur Verbindung verchromter Gegenstände durch Schweissen.    Es ist bisher im allgemeinen nicht möglich  gewesen, verchromte Gegenstände, einerlei ob  elektrolytisch oder auf thermischem Wege  hergestellt, durch Schweissen miteinander zu  verbinden, da einmal die Verbindung als solche  Schwierigkeiten bereitete, ferner aber auch  Mängel dadurch entstehen können, dass die  Verchromung als solche an der Schweissstelle  leidet oder hierbei Poren oder dergleichen  entstehen, so dass das Grundmaterial offen  liegt, also den Verchromungsschutz nicht  mehr besitzt.  



  Diesem Übelstand lässt sich erfindungs  gemäss dadurch abhelfen, dass man an den  vorgesehenen Verbindungsstellen die zu ver  chromenden Gegenstände mit einem korrosions  beständigen Material vorschuht. Hierzu können  beispielsweise 18 oder höher %/o ige Chrom  stähle verwendet werden, auch sind andere  ferritische oder austenitische, nicht rostende  Legierungen geeignet, die unter Umständen,  wie auch die reinen Chromstähle, Molybdän  oder Kupfer oder auch andere Legierungs-    bestandteile einzeln oder zu mehreren enthalten  können. Zweckmässigerweise wird man mit  solchen Legierungen vorschuhen, die schweiss  unempfindlich sind, also zum Beispiel Titan  oder Tantal oder Tantal und Niob enthalten.  Die Vorschuhung beschränkt sich nicht auf  Bleche oder dergleichen.

   Das Verfahren ist  auch für Rohre oder andere Gegenstände geeig  net und ermöglicht auf diese Weise auch ohne  weiteres die Stumpfschweissung in ihren ver  schiedenen     Modifikationen.  



  Process for joining chrome-plated objects by welding. So far it has generally not been possible to connect chrome-plated objects, irrespective of whether they are produced electrolytically or thermally, by welding, since the connection as such caused difficulties, but also defects can arise because the chrome-plating as such the welding point suffers or pores or the like arise, so that the base material is exposed, i.e. no longer has the chrome plating protection



  This drawback can be remedied according to the invention in that the objects to be chromium-plated are provided with a corrosion-resistant material at the intended connection points. For this purpose, for example, 18% or higher% chromium steels can be used; other ferritic or austenitic, rust-proof alloys are also suitable, which under certain circumstances, like pure chromium steels, molybdenum or copper or other alloy components, individually or in groups may contain. It is expedient to use alloys that are insensitive to sweat, for example contain titanium or tantalum or tantalum and niobium. The pre-shoeing is not limited to sheets or the like.

   The method is also suitable for pipes or other objects and in this way also easily enables the butt welding in its various modifications.

PATENTANSPRUCH: Verfahren zur Verbindung verchromter Gegenstände durch Schweissen, dadurch ge kennzeichnet, dass die Gegenstände an den durch Schweissen zu verbindenden Stellen vor der Verchromung mit einem korrosionsbestän digen Material vorgeschuht werden und nach der Verchromung die Schweissverbindung an den vorgeschuhten Stellen hergestellt wird. PATENT CLAIM: Process for connecting chrome-plated objects by welding, characterized in that the objects are pre-shoed with a corrosion-resistant material at the points to be connected by welding before chrome-plating and the welded connection is made at the pre-shod points after chrome-plating.
