Fig. 1 Procedure of friction stir welding
Analytical Modelling Friction stir welding consists of the basic three operations of welding tool for objective materials as (1) rotate, (2) plunge and (3) move, as shown in Fig. 1.
The tool used in this experiment had a shoulder with 8mm-diameter and a probe with 3m-diameter and 1.7mm length.
On the other hand, clear differences appeared in the torque and the temperature; 3.88Nm, 454°C at the lower revolution of the tool and 2.41Nm, 479°C at the higher revolution.

The weight ratio (W) of salts/oxides was 1:1. 3mol% excess PbO was needed to compensate for PbO loss during sintering.

Experimental Part A set of experiments, which the database programme contains, were performed in Laboratory of Liquid Jet in Ostrava where a technological system created at Department of Manufacturing Processes Operation that is schematically displayed in Fig 1 was used for vibration measuring, processing and evaluating [1-4].
Fig 1 represents the technological system schematically displayed and described in a configuration for evaluation of vibrodiagnostic signals from Source A.
After choosing the corresponding parameters, a course of vibration acceleration amplitude within frequency spectrum of 1 – 4,200 Hz is displayed.
