Abstract

A method of laser beam welding of galvanic cells in the process of production of a battery module consists in physical connection and electric serial and/or parallel connection of galvanic cell electrodes via a connecting element of an electrically conducting structure under the laser beam welding method. The process of laser beam welding of the electrodes of the galvanic cells (2) is preceded by a non-contact three-dimensional measurement of the position of the connecting elements (3) which connect the electrodes of the galvanic cells (2), where the measurement is taken using a measurement taking system (8), following which, based on the said measurement the position of welds (6) is determined and the result is sent to the software controlling the welding head (7). Then, the said welding head (7) is used to carry out the process of laser beam welding of the connecting elements (3) to the electrodes of the galvanic cells (2) to achieve the pre-determined connection thereof, where during the said non-contact three-dimensional measurement of the position of the electrodes of the galvanic cells (2) and during the laser beam welding process the connecting element(s) (3) is (are) pressed to the said galvanic cells (2).

Abstract

The method of protecting the sieve wall of the combustion chamber of a fired heat exchanger is characterised in that before a fired heat exchanger (1) is started, the control unit (9) of the fired heat exchanger (1) is pre-programmed with a limit temperature Tg adopted for the sieve wall (5) of the combustion chamber (3), whereupon, during the operation of the fired heat exchanger (1) the actual temperature Ta of the sieve wall (5) of the combustion chamber (3) is measured on the side of the water chamber (4) using an additional temperature sensor (T4), the signal from which is supplied to the control unit (9) and processed, following which the value of the actual temperature Ta is compared against the limit temperature Tg, and when both values are equal, the control unit (9) generates an alarm signal off. Once the fired heat exchanger is off, the limescale accumulated on the sieve wall (5) of the combustion chamber (3) is removed in any known way. The fired heat exchanger is fitted with additional sensor of temperature (T4) fixed in the socket (12) on the sieve wall (5} of the combustion chamber (3) on the side of the water chamber (4), and connected, either via a wire or wirelessly, to the control unit (9).
