The article refers to the issue of incomplete penetration in T-joints allowed by the obligatory Eurocode EN 1993-1-8. Based on it, the joint’s model was made, and then they were FEM simulated in various load combinations. As a result of this simula

The aim of the research was to analyse the processes of degradation observed in a dissimilar welded joint of T91 steel. The analysis was performed for welded joints after long-term annealing for up to 8000 hours at the temperature of 600oC. Microstru

The paper presents a comparison of simulated welding tensions and deformations created in plates designed as sealed walls. It has been shown that welding of sealed wall elements with fillet welds leads to higher tensions and defor- mations by 25÷35%

Explosion welding is one of the ways of bonding materials. This method is used to bond metals which either cannot be joined or they are difficult to bond by other methods. The study investigates the metallographic characteristics of Ni/Ti joints in t
