The paper presents the important influence of acoustic parameter - the amplitude of ultrasonic oscillations on the quality of ultrasonic joints of materials - in a statistical study and finite element analysis. The paper show the important influence in ultrasonic joining process of ultrasonic oscillation amplitude, programmable parameter in the process, along with basic energy parameters of the ultrasonic welding process, welding time, welding force,

The paper presents the assessment of the interaction between microstructure and mechanical characteristics for polyurethane materials used in automotive industry for components production. Two types of thermoset polyurethanes with the commercial name Necuron 1020 and Necuron 1300 are investigated. The paper present issues regarding the structure and microstructural imperfections influence on the mechanical properties related to operating conditions.

The paper presents how can be integrated and evaluated the risks in industrial process. Implementation of integrated risk management system involves consideration of all risk types such as technological risk, financial risk, environmental pollution and natural hazards. To treat the risk it must be defined, identified using the group creativity techniques or structured and systematic examination techniques, analyzed and quantified in terms of risk

This paper present the damage state and remaining life assessment for a metallic structure from 16Mo5 steel, using the nondestructive method of metallographic replicas and the assessment of this replicas using the A parameter and VGB 507 standard. For results interpretations we used the expert system iRiS Power, which allowed to determinate the steel grade degradation and remanent life estimation.

The paper presents an application of risk based inspection concept on boiler components from fossil power plant. It was used the expert system RBI (Risk Based Inspection), named iRiS - Thermo, who was purchased by the ISIM. It is started with first stage which consists of application establishing. The system contains 9 components. Then it is presented the data collection and validation step. There are applied three levels of assessment (screening,
