Celem artykułu była ocena wytrzymałości złączy wykonanych z blach z tytanu grade 3 i grade 4 o grubości 0,4 mm. Blachy łączono w sposób zakładkowy przez zgrzewanie oporowe. Złącza zgrzano pojedynczą zgrzeiną RSW. Dokonano wyboru optymalnych parametrów zgrzewania. Ocenie poddano złącza wykonane za pomocą 5 kombinacji parametrów zgrzewania, różniących się czasem zgrzewania i natężeniem prądu elektrycznego. Analizowano nośności na ścinanie złączy, rozkład odkształceń plastycznych i sposób pękania. Pomiaru odkształceń plastycznych dokonano przy użyciu bezkontaktowego systemu analizy optycznej Aramis.

Titanium and have been identified as one of the best engineering metals for application in many industrial fields such as aviation, automotive and civil engineering. This is because of properties of the material: low density and high mechanical strength. Titanium also is characterised by excellent corrosion resistance to many environments. In recent years, researchers have attached great importance to the application of titanium in resistance spot welding (RSW). In resistance spot welding, two metal sheets are placed between two copper electrodes. The purpose of the two electrodes is to supply current to the weld sheets. The production of RSW welds is finished via solidification. The paper presents a strength evaluation of welded specimens made of titanium grade 3 and grade 4 of 0.4 mm thickness. The lap joins were made by Resistance Spot Welding (RSW). The joints were welded by the single RSW weld. The optimal welding parameters were chosen. The joints welded by 5 variants of welding parameters, different of welding time and electric current. The shear load capacity, a plastic strains distribution and a method of cracking were assessed. The Plastic strains measurement was made using a non-contact optical deformation system Aramis.
