AB The paper is aimed at the analysis of a welded band-saw blade joint. The analysis is focused on the influence of joint annealing on the microstructure and mechanical properties. The results of experimental work are focused on an assessment of a set of band-saw blades samples made of material DIN C75. The samples have been welded and evaluated in the states prior and after welding and annealing. The purpose of the experiment was to analyse the influence of different annealing temperatures on structural and mechanical properties and based on the analysis to propose optimal heating temperature that guarantees reliable operation of the band-saw blades. The results of hardness measurement and microstructure evaluation confirmed the need of annealing after welding of band-saw blades.
