Sekundarni naslov: | Effect of multi-pass weld bulid-up on weld-metal toughness |
Sekundarni povzetek: | The influence of a weld's thermal cycle on the microstructures and the impact toughness of the weld metal are experimentally analysed. For this purpose we used the SMITWELD simulator for the thermal cycle. With a simulator for the thermal cycle it is possible to simply reproduce the microstructures of a heat-affected zone and the microstructures of the weld metal. Also, it is possible to simulate the segregation proces as part of the weld's thermal cycle. For this purpose a different thermal cycle with a different peak temperature on a real single-pass weld joint produced by submerged arc welding was used. With this experimental work the simulation of the effect of weld build-up on the weld-metal toughness and the formation of a local brittle zone in laboratory conditions was performed. |
