Abstract

Woodworking industry uses in mass band-saw blades. Their material is mainly unaloyed eutectoide steel. The load characteristics are followed by the presentation of the typical failures. The first significant failure type is concentrated to the weld and the heat-affected zone, where the welding heat process causes the decreasing of toughness. The second but much frequently affected part, where cracking may apear is the gullet, because it raises the stress intensity factor. Following 15 year‘s experiences and researches it was developed an expertise system for failure analysis of band-saw blades. This expertise system is demonstrated by case studies.
