An ideological structure of a computerized database is proposed, which would allow to collect and edit data on welding materials and welding modes, to systematize them, as well as to display the necessary user information on the screen by processing various requests. The complex of harmful and dangerous factors accompanying welding processes is analyzed. The method of mathematical modeling of the dependence of the intensity of welding aerosol release on the set of technological factors is given and the necessity of its improvement is argued. The urgency of creating an information-analytical system of complex sanitary assessment of welding materials for the selection of optimal, from a hygienic point of view, welding technologies is substantiated. The advantages and disadvantages of the existing developments of information-analytical systems of managerial decision-making in the welded production are given. The structure and conceptual aspects of creating a new database for the computer system of information support of complex sanitary and hygienic assessment of welding technologies and materials, in accordance with modern requirements of the standard DSTU ISO 15011- 4: 2008.
