The publications increasingly describe the support of production processes in both manufacturing and assembly areas. The support in industry is due, among other things, to the insufficient manpower, the need to improve productivity or to increase reliability of production in terms of errors. This article presents an example of an industrial implementation in the welding area. The main objective of the application of the presented example was to replace a commercial product and to speed up the manufacturing process of an axisymmetric workpiece of the sleeve type. The presented proposal was implemented in a company where welding is the main manufacturing technology.

High-frequency electromagnetic fields (EMF) can have a negative effect on both the human body and electronic devices. Monitoring and measurement of the electromagnetic field generated by devices is important from the point of view of environmental protection, the human body and electromagnetic compatibility. In this study, we tested the value of the electromagnetic field strength determined by the NHT3DL by Microrad with measurement probes during flights in the Robinson R44 helicopter. The reference point for the results obtained were the normative limits of the electromagnetic field permitted to affect the crew and passengers during flight. The maximum RMS values recorded during the measurements were E = 4.399 V/m in the 100 kHz-6.5 GHz frequency band and for the magnetic component H = 2.829 A/m in the 300 kHz-30 MHz frequency band. These results were passed to the Statistica 13.3 software for a detailed stochastic analysis of the values tested.

The working surface of lift guide rails during operation is exposed to the destructive action of catchers under emergency braking conditions. In most cases, this surface is lubricated with grease, which makes it impossible to visually assess their local wear. The comfort of cabin movement on guide rails and thus the feelings of cabin occupants depend on the condition of guide rails. Therefore, the verification of lift guide rails wear under real conditions (in situ) is quite cumbersome. In order to assess them on a monthly basis, they would have to be completely cleaned and the excessively worn areas would have to be measured with universal measuring tools and re-lubricated. Such activities would only be a waste of time and lubricant.
