  Verfahren zur Prüfung der Warmrissigkeit von austenitischen
Stählen und Legierungen 
 EMI1.1 
 

 <Desc/Clms Page number 2> 

 sind ziemlich hohe Bestände an Vormaterial bei den Schweisselektrodenfabriken erforderlich. 



   Nach dem Verfahren gemäss der Erfindung kann die Prüfung durch Argon-arc-Punktschweissung bereits z. B. am geschmiedeten Knüppel, durchgeführt werden. Das gewährleistet die Ersparung aller nachfolgenden umfangreichen Fertigungsarbeiten an einem Stahl oder einer Legierung, die sich bei der Prüfung als rissempfindlich erweist. 



     In den Figuren sind einige Argon-arc-Schweisspunkte   an austenitischen Stählen gezeigt (bei vierfacher Vergrösserung). Die in Fig. 1 und 2 gezeigten Punkte lassen eine deutliche Rissbildung erkennen, während nach Fig. 3 Rissfreiheit vorliegt. 



   PATENTANSPRÜCHE : 
1. Verfahren zur Prüfung der Warmrissigkeit von austenitischen Stählen und Legierungen, bei welchen schon Proben punktartig angeschmolzen werden, dadurch gekennzeichnet, dass diese Proben dem Argon-arc-Punktschweissen unterworfen werden.

 <Desc / Clms Page number 2>

 the welding electrode factories require fairly high stocks of raw material.



   According to the method according to the invention, the test by argon arc point welding can already be carried out, for. B. on the forged billet. This ensures that all subsequent extensive manufacturing work on a steel or an alloy that proves to be susceptible to cracking during testing is saved.



     Some argon arc welding points on austenitic steels are shown in the figures (at four times the magnification). The points shown in FIGS. 1 and 2 show clear crack formation, while according to FIG. 3 there is no crack.



   PATENT CLAIMS:
1. A method for testing the hot cracking of austenitic steels and alloys, in which samples are already melted in a point-like manner, characterized in that these samples are subjected to argon arc point welding.
