Evaluation of Load Bearing Capacity of Resistance Spot Welding (RSW) Joints Made of Titanium Gr 5 Sheets
The paper presents an analysis of load capacity for welded specimens made of titanium Grade 5 of 0.8 mm thickness. The lap joins were made by Resistance Spot Welding (RSW) The load capacity for joints with a single spot were assessed. The joints were welded with 5 variants of welding parameters. On the basis of the capacity of the joints, the best performance were selected. The best welding parameters were used to make three types of joints with different spacing of the welds: with a single weld, the two welds arranged parallel to the shearing direction and two welds arranged perpendicular to the shearing direction. The load capacity, a plastic strains distribution and a method of cracking were assessed. An example of the feasibility of a beam construction made of titanium grade 5 sheets welded by resistance spot welding were shown.
