Abstract

Przedmiotem zgłoszenia jest sposób podwyższenia wytrzymałości na rozciąganie i wytrzymałości zmęczeniowej w spawanym złączu blach ze stali wysokowytrzymałych poprzez spawanie procesami bezżużlowymi MIG/MAG, w którym spawa się doczołowo w pozycji podolnej, w gazie lub mieszance gazów osłonowych, który charakteryzuje się tym, że bezpośrednio przy układaniu ściegu spawalniczego wprowadza się głowicą spawalniczą mieszankę gazową, osłonową z zawartością 2% - 3% azotu.The subject of the application is a method of increasing the tensile strength and fatigue strength in a welded joint of high-strength steel sheets by welding with MIG/MAG slag-free processes, in which butt welding is performed in a downward position, in gas or a mixture of shielding gases, which is characterized by the fact that directly at When laying the welding bead, a shielding gas mixture containing 2% - 3% nitrogen is introduced with the welding head.
