Abstract

La présente invention : fournit une embase de poteau tubulaire en acier et une méthode pour renforcer l'embase de poteau tubulaire en acier qui ne permettent pas à la force de baisser dans le voisinage de la patte de soudure d'une arête d'exploitation même en cas d'application de flexions répétées ; et se caractérise par la formation de parties traitées par martelage 20 par vibration ultrasonique aux pattes de soudure 16 des arêtes d'exploitation tabulaires 12 soudées à l'embase de poteau tubulaire en acier 10 sous la forme d'une jointure en T ou les pattes de soudure en U inversé 13 ou des arêtes en v inversé 14, les arêtes étant courbées aux parties de l'extrémité supérieure, soudées à l'embase du poteau tubulaire en acier 10 sous la forme d'une jointure en T. Des conditions de traitement préférables sont de 20 à 50 µm d'amplitude et de 10 à 50 kHz de fréquence. En particulier, la présente invention permet d'améliorer remarquablement la propriété de fatigue parce que la concentration de contrainte est relayée par l'effet synergétique de flexion des parties de l'extrémité supérieure 16 des arêtes 13 et l'application d'un traitement par martelage.
